I call it this because the final two foundational skills are related to movement. Breathing and buoyancy are in play at all times when we dive. If we are stationary, these two pillars of Precision Diving have the largest impact. Diving being active, we do not sit still all that often and when we do it tends to be for short periods.
The final two pillars of Precision Diving are all about movement. This is why I present them together. Swimming and trim are the cornerstones of our movement as divers. Swimming is how we actually create the movement. Trim is how we control how the water moves past us. Or how we move the water out of the way when we move through it. Of course, breathing and buoyancy need to be ideal and are in play as well. But, the choices we make in how we move, position ourselves, and configure our gear has big impacts on our performance while we dive.
Most divers learn to flutter kick. There is nothing wrong with that. I do wonder why it stops there with most new divers. There is nothing preventing an instructor from working on more than one way to use the fins. Well, perhaps motivation and a bit more time. But, if you are a new diver or about to become one, demand to learn more than one way to kick/propel yourself. It is important and it will serve you well to learn this early and have the choices be automated early for you.
Precision Diving is not about one type of gear or one style of anything. This holds true for fins. A good diver should be able to use any fin. The choice of what is good is a very individual thing and should be done through trying many out and then making the choice for which fin best suits your needs and diving. You may find that you choose more than one pair of fins for different activities.
I use different fins for daily diving then I do for cave diving. I use another type of fins when I freedive and even sometimes use a monofin. So, select fins that work best for the performance you need out of that tool when and where you need it.
Of course, when you are new, you need to start with something. So, this is where is pays to have a good relationship with your instructor. Make sure you have a good conversation about what type of diving you plan on doing and where you plan to dive. Once your instructor fully understands your needs, then you can consider their recommendation.
Fins are important. They are the engines by which we create our movement underwater. Invest in something good. Fins tend to last a very long time and most people do not buy new ones because they wear their fins out. Usually new fins are purchased because there is a new feature someone wants. It is important to make sure the fins suit you and your diving. In spite of what some say, no one pair of fins works for everyone in all applications. Those that disagree, I am very happy that you have found something that works so well for you personally. However, this is not true for all.
A fin that is too stiff can cost you more energy and create more work for you if you are not prepared to use them. This will take bottom time away and you will consume more breathing gas. This is not optimized performance and not Precision Diving.
Some fins may be too negatively buoyant for your body composition. This will cause your feet to sink and you will need to make other compensations to counteract that shift in buoyancy. This is possible to accomplish, but at what cost? It might be simpler and better just to consider another fin. One that is less negative. Perhaps simply made of another material in the same style you like.
The same holds true if your feet tend to float. A more negatively buoyant fin may be the best solution rather than adding ankle weights or making some other compensation. Make sure if you do adjust for floating feet, that you do not go too far the other direction causing you to have to fight negative buoyancy in your feet now.
It is important to consider the kicking style and learn the correct one for the fin you use. This means it would be wise if you change fin style and that new fin requires a different technique that you request some time with an instructor comfortable in tutoring you in the finer points of this new technique. At least get good input on what those differences in technique are.
Split fins are very different from straight bladed fins. Other fins have very unique kick styles needed to optimize their performance. It is important to understand what your fins require. If you go on to use more than one style of fin, you will need to make sure you master each style’s required techniques and also create a ritual around each fins’ use to help you be able to seamlessly move from one to the other with minimal workup in between.
Just as we do not assume that breathing is something we know how to do as Precision Divers. We do not want to assume that we should “just know” how to optimize performance in any fin. I hear it all the time, “It is just fins.” Um, no it is not. Most divers that began with straight bladed fins who switch to split fins tend over kick them with far too great a length of kick. This only blows water through the split defeating the purpose of the design. Similar issues are faced by those making the switch the other way with under kicking. Other designs can be equally difficult.
Fins are the engines of our diving. So, make sure you understand how to get the best performance from your engine before you assume you “just know”. We generally do not jump into a car we have never driven without first “figuring out where everything is”. Make sure you do the same with your fins. If you get resistance from your instructor about a demand to work on use of fins, then find a new instructor. Same for a retailer. If the shop you use does not want to help you learn how to better use the gear they sold you, then it is likely time to find one that will. They should charge you for this service as well. You want to make sure that the service is provided fully and not blown off. Pay peanuts, you get monkeys.
Most shops would be surprised at the request, but more than happy to provide the education. I find that resistance to such requests is more a reflection on the possible lack of knowledge and/or understanding of the person you are talking with rather than a lack of necessity. Any major change in gear should automatically be followed up by time in a pool. More on this in a future post.
So, fins are the engines. With such a good engine on our feet, it means we should not need to use our hands to dive. If you are diver, this is the one thing, once you are aware, that will have you looking at divers very differently. You will begin to notice just how much even some highly experienced divers use their hands for all sorts of movements. Newer divers tend to use their hands a lot. Well, new divers that are not trained to not use them. But, the use of hands for controlling our diving is a crutch and should not be happening.
I am well known for asking people in my talks, “What are your hands used for in diving?” My answer is usually a less polite version of “for holding stuff”. Here is the problem if you rely on your hands in any form to control yourself while diving. The second you need to use your hands from something else; you just handcuffed your ability to dive. So, when you need to actually hold something, now you cannot dive as well as you did before having to hold something. Precision Diving is about being able to dive just as well either way, in fact all the time.
Let’s go back to our first post example of handing a diver a camera. Yes, there is the distraction factor. But, you very quickly realize that the diver with the camera had better be able to control their diving without the use of their hands. Because they just tied them up. It is easy to see. Those that have good skills and have learned to not use their hands make out better than those that have not, often in dramatic fashion.
This is true of dogmatic arm and hand positions as well. Most of which come about because the diver simply does not know what to do with their hands. So, they ritual a swimming position that locks them up. Well, this can work in the short term to have them looking better, but the same problem remains, when they need to perform in another way it throws the whole system into a tailspin. Performance suffers.
Try not to get locked into any one way of where your hands should be. In fact, get good at being able to dive the same way no matter where your hands are and in lots of places being used for lots of things. Just not used to control our diving in any way.
I will speak about the hands in front swimming style and other issues later in this post.
We have dialed in our fins and we are not using our hands. The next thing to do is make sure you understand swimming. Propulsion through the water is a lot of work. So, we want to make sure we do this as efficiently as possible with the choices in swimming we make.
I ask people all the time, “what is the most important part of swimming when we dive?” A lot of answers come flying back. My answer surprises most. The glide. Gliding is why we swim. Not the movement of swimming, but the motion we gain after we kick. You see a lot of divers just always finning. They clearly do not understand this concept.
The next time you dive, ask yourself, “Self, how much glide am I getting out of my kick?” The glide is the space between the notes on the sheet of music. It is to swimming what breathing is to all of diving.
This is why we need to talk about movement as a whole. Our glide is a function of swimming, but also a function of how much water we need to move out of our way as we swim and resistance as well. More of this is a sec.
As a diver, there are four finning styles we should know: Flutter, Modified Flutter, Frog Kick, and Modified Frog Kick. The modified version of each is simply a way to prevent the fin wash from going down to the bottom when you want to make that decision. Which is most of the time. Reach out to your instructor for help and if not them find one that is happy to help.
There are many other finning styles and it is fine to learn all of them. Just make sure you master these four first. Really, you want to get very good at each one before you add a new one to the mix even for these four. Until you are sure your kick is the best it can be it is going to be pretty difficult to figure out if other factors are affecting your ability to glide between your kicks.
Once you are feeling good with the kick, it is good to get some video footage of you doing it. Video analysis is the best tool to work on improving your performance. Also, it is much easier to see what you are doing and understand than trying to hear someone’s explanation of what they think you are doing. It is best to have both. With the advent of inexpensive high quality video systems, this is pretty easy to accomplish without needing someone dedicated to doing the video.
Now, kick and get moving. Once you get a few kicks in, see how long you can glide after each kick. Begin to play with how you kick and how often you kick. Which ways maximize your glide? This will change with your kit, your conditions, what the water is doing, and several other factors. Optimize and maximize your glide. The easiest and best place for this work is in a pool. The pool tends to minimize the impact of any factors outside of your performance.
Once you get good at moving forward, you can begin to work on flat turning. Flat turning is a fancy way to say turning using your fins to do so without any forward movement. If you get good at Modified Frog Kick first, then turning yourself with just the use of fins is easier. This helps provide that control that most feel they gain with the use of their hands. The fins will always do it better and more efficiently than your hands. Plus, you are more likely to have control of where the wash of that movement goes.
We work on flat turns because it is more difficult to do stationary. Once we get good at these, we can easily add slight movement in as we swim and glide to create turns. The layers of subtly grow as you get more refined in your control. Greater ability to control our diving is what gives us confidence. The faster that happens the more likely we will enjoy our diving more.
Eventually, you can learn to use your fins to move backwards. Yes, even with split fins. Moving backward is helpful when you are unable to turn around easily and often used by photographers when they are head down and looking under reefs or ledges.
All of this is connected with breathing and buoyancy. How and when we breathe and where our buoyancy is has profound impacts on our swimming. As Precision Divers, we use our control over all of this to optimize our performance. It is important we understand and have automated all our foundational skills so we can build to this level of integrating them together. If that integration is difficult for you, then go back to the individual foundational skills and work on them. The better the foundational skills are in basic applications the more likely it will be easy to use them in an integrated fashion. More in a future post on this topic.
If you begin to watch divers, which you will now, you will see that often swimming is used to compensate for other issues in the foundational skills. It is pretty common to see divers try to swim out of bad buoyancy. Swimming creates lift and that forward movement can have it appear to the diver that they are neutral because of the forward movement creating water flow over the divers body at a different speed above the diver than below. However, when the diver stops they immediately sink. Not to mention what the hard kicking does to their visibility and the environment, always fun for your fellow divers as well.
We know from the post on breathing that we can use our breathing control to compensate for this in the short term. Often, most divers try to swim out of it. Stop being that diver. If you feel you need to move to be neutral, do not swim more, fix the issue then swim.
Clearly, you are not going to get as much glide if you are swimming all the time because you are trying to fix the issue with your buoyancy. In fact, I doubt glide is any where near being on your mind at that point.
When we swim we should be able to stop at any point and not move at all. Well, unless we want to create that movement with our breathing control. Hopefully, with some forward glide at the end of the last kick. That is control and that should be our decision. Not a happy accident. So, make sure it is you making that happen at all times.
Other things like swimming backwards or backing out after looking under a ledge can be made easier by thinking about how we use our breathing as we do it. We know if we choose to cycle our lung volume near full our head tends to raise. So, if we cycle lung volume lower in the lung we can help to create a rise in our feet. Or perhaps our feet are already slightly elevated. Either way, we can use our breathing to help the backward movement out a bit. A bit of positive buoyancy controlled by our breathing as we create some backward movement is going to help our up and away movement. This reduces the amount of finning we need to do in order to create the desired backward movement. Also, it allows us to use less backward kicks to make the desired movement happen. This is a good use of lift to help desired movement.
Hands locked in front is being seen more and more these days. For most, it is just compensation from being uncomfortable with their hands and trying to lock them up so they will not use them. But, it also generates lift. For most, it is compensated for slight negative buoyancy. Subconsciously, this could have come about from feeling better about not losing control via positive buoyancy when they were newer or perhaps just a bad habit.
It is not necessarily a bad habit to have the hands locked in front, but you should be able to dive exactly the same with your hands in any other position as well. It creates the same problem as we discussed earlier in this post. What happens when you need to actually use your hands for something else, like holding something? If the answer is nothing happens, perfect. Then, this truly is a choice. If the answer is you do not dive as well, it needs to be fixed.
Use of lift in our swimming is a very important idea. As you progress, you are going to realize that you can use lift and buoyancy to move without swimming or to aid our swimming. You might even be told you move too fast and you respond with I was barely kicking at all. We can use negative lift on descents to literally fly on a down slope. Our fins then become rutters helping to change direction. If we want to flatten out we simply inhale a bit more, drop the tips of our fins a touch, and cycle our breathing there to stop the descent and exhale to restart it.
We can do the same on ascents, using our lung volumes and how we cycle our breathing to ascend without ever having to swim. This minimizes work and provides a great sense of control and confidence. All we have to do then is breathe and let bits of gas out of our BCD. Super easy to slow the ascent when it is our breathing and lung volume doing it. There are submarines that use changes in ballast and where it is held to move through the water without the use of propellers.
Refining finning skills and adding new tools to your performance toolkit is important. We also need to look at how trim and hydrodynamics impacts our movement as well.
Water is heavy. I will try to keep the math to a minimum. If we are moving through the water, we are moving water because we are forcing it to flow around us. Even small changes in how we make contact with that water can have real impact in the amount of work we need to do to move it.
Ideal positioning is how we optimize that. If we are not moving, then ideal positioning is not so important. If we are hanging out on a safety stop in blue water, it is not so important to be in any position. There is some research that shows some positions may benefit off gassing better than others, but there is still not much data either way. The point is; if we are not moving, how we move is not going to be in play at that time.
Ideal position is a flat position that minimizes the surface area that interacts with the water as we move. Generally, the torso is parallel to the bottom with a slight arch in your back. This helps you to see forward without having to crank your neck and/or not having to elevate your head, which would create more drag. Legs inline with the torso with a slight or more bend in the knee. This will depend on the kick you are selecting. This position is your default position when near or close to the bottom. It will be comfortable and easy once you get used to it.
One easy technique to help you “feel” it is to go to the bottom of the shallow end of the pool and be a bit negatively buoyant. You should feel the pool bottom from you knees to your shoulders for the most part with a slight arch to your back. Inhale and create some positive buoyancy and then drift back down and see if you can land in the same way feeling the same things. It is a good exercise to help you feel it. I find video really helps here. Project it on to a white board and draw your horizontal line inline with where you should be. If you match the line you are doing great. Assuming that is the goal at the time.
If you are going to put this much work into your positioning, you want to make sure you streamline your kit to match your work in streamlining you. So, watch your accessories. Clip them in tight to your body. If you are a fan of retractors, figure out how to use them without having them have what is attached to them dangle down. Consoles and SPGs should be brought in tight to the body and clipped up. No sense in having them create drag when they are not being looked at. Optimize your kit by routing hoses down and in. One small thing is not likely to make or break you, but lots of little things can add up to more than you think.
Water is heavy and having to move more of it requires more work. More work means more gas used and less time underwater. The goal is to minimize anything that is unnecessary work. Seawater is 64 pounds per cubic foot. For our metric friends, that is about a kilogram per liter. In theory, if I present one square foot of surface to the water and I swim one foot forward, I would need 64 pounds of thrust to make that happen. If I move the same foot with only somewhat poorer streamlining and present three square feet of surface to the water, I now have to provide 192 pounds of thrust to move a foot forward. For our metric friends, the numbers do not matter, the message is clear, bigger surface area, much more work.
So, small things like elbows sticking out, or a console and hose, or poor swimming technique that stops glide, or a combination of all or more can quickly add up to a lot more work. This means more gas consumed and less bottom time available. Several small improvements in streamlining will add up.
Drag also matters. Drag punishes speed. You need to move a lot of water out of your way as you swim. This takes work as we have seen. If you want to do that while going fast, it takes a lot more work.
FD is the force of drag, which is by definition the force component in the direction of the flow velocity,
ρ is the mass density of the fluid, 
v is the velocity of the object relative to the fluid,
A is the reference area, and
Drag is calculated with velocity being squared. The important take home message is that the faster you go, the more you have to work in a function of how fast you go multiplied by itself.
I like to say with diving you need to slow down to speed up. If we move slower in the water, it requires less work. If you have good trim and streamlining, that is even less work. We want to give time for the heavy water to move past us. Ironically, when we move slower we get more glide, we get more out of our glide as it is more of our movement per kick. Also, it is likely that our technique is better when we are not rushing. Plus, our technique does not have to be as good when we more slower. Of course, we want to optimize our performance at all times, but there is a tipping point with work and speed where you will move faster and further by slowing down than if you try to go faster. You want to find that point and refine even more.
Technique matters. I have asked students to swim lane lines on the bottom of the pool and to get to the other end as fast as they can. They go screaming out and forget all technique, gas pumping through their lungs with a stream of bubble arching up behind them. I time the effort of course. When they are done, I ask, “What happened to your technique?” Oh yah. I then tell them to repeat the swim again, this time as fast as possible, but with the very best technique you can perform and maximizing glide. Which one do you think is faster?
The result is dramatic. Often, the results are 20 to 30% faster even though they feel they were going much slower the second time through. Thus, proving to them that slowing down actually speeds you up. Literally.
If you are not able to stop at any time in your diving and stay in the position you want to be in, then you want to work on these techniques. You can move weight higher or lower on your body to help, but it might be a better answer to look at potentially other choices in fins or other gear if the stuff you have is creating a problem that other kit will fix easily.
If you are diving dry, then learn to manage your bubble in your suit. Trim is much easier in a drysuit because your buoyancy is spread out over your whole body. But, you want to make sure you become intuitive with managing and breaking that bubble up into smaller pieces allowing you to feel in control of where your buoyancy is in the suit. Bubble management, if you will.
As you progress, you will refine your awareness and techniques. With this growth in your ability to dive well, you will work on subtler and subtler areas. Also, you will become much more sophisticated in the techniques you can use to control your diving and have a lot more tools to do the same thing in different ways. I will post about more subtle aspects in smaller posts in the future.
Be better this dive than the last one and better next dive than this one.
As I have promised, the first post on Buoyancy has arrived. Pretty much everyone would agree that buoyancy is one of the critical skills in diving. What does that actually mean? We spend a lot of time discussing the topic in pretty much every course, but do we ever do a good job truly getting the diver to understand what this means and what it looks like when we are good at it.
It is impossible to discuss buoyancy without discussing breathing. It is why that post came first. Buoyancy is so critically linked to how we breathe and how we change our breathing that really the two are very much linked. It is also why we need to master and understand ideal breathing for scuba prior to trying to improve our buoyancy and the control of it. Or use lung volume and where we build volume in our lungs to further refine buoyancy.
That is what caring about and paying attention to this results in, control. With control comes confidence. Ideally, each diver should be confident in their diving within appropriate development for their level of progress in training and experience. If you do not feel confident in your diving at any level, get back to the basics. It is the foundational skills discussed in my first post that will bring you the confidence and execution you desire.
So, now that you are working on ideal breathing, we can look at how we can dial in our buoyancy control. Working position is tied to buoyancy, but pure buoyancy control is what needs to be mastered first. This means that we should be able to stop at any time in our diving and not move without a change in lung volume. So, we are neutral at all times. Unless we choose not to be. It should be a choice.
There are times when you will choose not to be neutral. On the surface, we usually choose to be positively buoyant so we can rest or swim to the boat or dive site. I find I have to remind new divers and sometimes not so new divers to use their BCD on the surface to not work once their head breaks the surface of the water. It is all about minimizing work and making diving easier where we can.
We may choose to be negative on the bottom to stabilize ourself in a nonimpactable environment while taking pictures or during an experience that requires us to stay on the bottom. If I am working in a strong current and hand pulling on the bottom, I usually like to be a bit negatively buoyant as well. Most professionals while teaching use negative buoyancy to help if a new diver has a problem and the instructor needs to arrest an assent.
For the most part, as divers we want to be neutrally buoyant at all times once we leave the surface. Being neutral is the weightless inner space experience that we all as divers crave and speak to non divers about as being magic. It is one thing to know what is feels like. It is another to have such possession of it that we are able to use its control to appear to be magic.
Buoyancy changes take time to happen when we dive. This delay can be different at different times depending on depth, gear configuration and other factors. But, for the most part when we make a change in buoyancy it takes two to four seconds to really take affect. This means we can use our control of buoyancy to compensate for wave action, picking up a weight, or wanting to use ballast to drive movement along with so many other things.
It also means we have to be patient and plan for this delay in action. So, we have time to work with it, but also if we do not pay attention issues can get worse over time. This is all assuming diving open circuit scuba. Buoyancy on a rebreather is very different and not so tied to changes in lung volume as open circuit scuba. I will discuss rebreathers in future posts.
In our beginning scuba courses we are told on descent to equalize the pressure in our ears and sinuses. This is a very important thing to do as it is the most common injury for most divers if not done properly. Easily avoided if we do it early and often and before we feel anything. More on this in a future post.
However, the corrective action prescribed if there is an issue is to kick up a bit and if negative add some air to the BCD. Conversely, if someone begins to drift up a bit becoming slightly positively buoyant we say let some air out of your BCD as the first action to take.
Why not suggest that the rising diver first exhale and then emphasize breathing with a reduced lung volume or on the bottom of the breathing cycle first and then make the adjustment to the gear? Additionally, on the negatively buoyant descending diver, why not tell them to inhale and then emphasize the upper portion of the lung volume and then take corrective action with their gear?
Of course, ideal breathing needs to be mastered in order to be able to chose to deviate from it in this way. But, is it not more controllable and more intimate to use our control over our breathing first than train people to go to their gear? Going to the gear first, as almost any instructor knows in newer divers, is not quick nor familiar. I would bet that any new diver knows where their lungs are.
If we all build a strong connection between our breathing and our buoyancy we can effectively add five pounds of negative or positive buoyancy or more at will within seconds simply by how we choose to change our breathing and emphasize cycling breathing at the lower or upper end of lung volume. I am suggesting this is going to help divers feel that they have more control and I think we can all agree is more accessible, intimate and quicker than fumbling for a deflation method only to have the wrong end of the BCD facing up.
Choosing to change breathing may not solve the problem completely, but it slows everything down. It provides time for a calmer approach to finding the right item to make more adjustments to buoyancy and the perspective to think about being in the correct position to do so. Most of us have seen the newer diver facing head down trying to dump air from their BCD while swimming down fighting positive buoyancy only to have the air in the wrong place in their BCD for their attempts to be able to do anything.
If this diver were to exhale and choose to deviate from ideal breathing by cycling on the bottom of their lung volume, they would take most of that positive buoyancy out of the situation. It could bring them back to neutral or even slight negative buoyancy or at least immediately drop the urgency of the situation down several notches. This gives the diver more time to think through why what they are trying to do is not working as they had hoped it to. More time, generally means less stress and more likelihood of success in correcting the situation rather than drifting backward toward the surface.
This is only one example of how much more layered the subject of buoyancy is. It is easier to see the results in an obvious situation with a newer diver. As you get better, you will see that subtle changes in where you emphasize lung volume can play a role in trim and swimming. How you release lung volume or add it can change lift and your center of buoyancy. We can begin to use our breathing to actually help us move better through the water and also allow us to work less.
I will speak to movement and trim in future posts. Buoyancy control and working with your breathing can allow you to change how you ascend. We are taught to reach up, look up, and come up, swimming to help the movement.
What if we were to ascend by using our breathing to emphasize different areas of lung volume on average to create rises toward the surface or to drop down a bit on a safety stop or to slow our ascent and adjust our BCD? When mastered, ascents can become literally almost no work. They are also highly controlled and slow because we are intimately in touch with the movements because it all comes from our control of our breathing and our lungs. Of course, we still need to vent excess gas from our BCD or drysuit and we do not want to hold our breath.
So, buoyancy is often talked about in diving and I know that we could fill a room with instructor trainers where “good buoyancy” would make everyone’s list of important skills to master. We need to expand our understanding of what this means. We need to tie the discussion intimately to breathing and how we find ideal breathing and how we choose to change from ideal breathing if we need to do so in order to affect our control over our buoyancy.
Buoyancy control is extremely important to good diving and certainly is foundational to the Precision Diver. It just does not live in as much isolation as we have been used to dealing with it in. In the near future, I will explore how breathing and buoyancy work together in how we swim and our trim in the water as well.
The foundational skills all work together built on top of our performance mindset to hold up the roof that is performance. With performance comes confidence in our diving.
I am back in the US after being in the Bahamas at Stuart Cove’s working with Joi Ito on his PADI Instructor course. See his post. Instructor training is not so much about teaching skills or knowledge, but more about helping the candidate become comfortable with presenting what they already know in an engaging and educationally valid fashion. Joi is already a seasoned public speaker, it was more formatting than great effort. But, it is fun to see even very experienced people create new connections and evolve into new roles. He did very well, by the way.
While we were there, Joi had the opportunity to also work on Instructor level specialties. One of these specialty areas was shark awareness. I will let his post speak for the experience. It is something that needs to be experienced to fully understand. I have been working with sharks for over 25 years and it is always amazing to be honored with their company.
Sharks have had the same appearance of today for over 100 million years. Generally, this means their body shape and function is pretty good for what they do. It is one of the coolest things about watching them, they are almost perfect at what they do. It was fun to get to share this with Joi.
Diving at the resort is quite good, especially off the beaten path. It has some of the most pristine wall diving I have found in the Caribbean. They also have tons of wrecks and many of which are very shallow, which allows for longer dive times and better conditions to practice penetration technics. Plus, everything is a quick boat ride. It makes for a very easy field to play in.
We also took a trip further afield to visit with Silky Sharks (Carcharhinus falciformis). They reside out in the blue and one of the best areas to find them is around the sounding buoy off of the island. The buoy is moored in 6000 feet / 1829 meters of water. When we pulled up and tied off there were two Silkies already there to greet us. I love being out in the blue with bottomless water and incredible visibility. Then, to get to enjoy pelagic sharks is even better.
The resort has a robust photo and video department where all of the shooters were quite skilled. It was very helpful to have their assistance from time to time to help document the trip and allow me to focus on teaching and grab some GoPro footage now and again.
I would have to say I was pleasantly surprised by my visit and would go back any time. It is worth the short flight from Miami to check it out. For teaching, you cannot ask for more choices in dive sites and almost any specialty area can be conducted there. Plus, the staff were very helpful and understanding of the needs for teaching.
Life has been busy as can be. I promised more on the performance mindset. I will have ongoing posts related to this topic, but I wanted to make sure that I get a post out specifically about it now.
The last two weeks I went from busy in Australia to a thirty-six hour turn around in LA to come to the Bahamas to work nonstop. I know, rough life. But, it reminded me of all the things that diving helps us do and actually not do. When we are underwater, diving allows us to escape mobile phones, commutes, daily grinds, E-mails, and so much more. It is part of why I do it and likely all of us. It is also why how we think when we go diving can be as important as how we dive. In fact, it may be how we think that is how we dive. At least to some extent. Or perhaps mostly.
Diving has changed my life for the better and forever. The best friends I have met relate to and are around diving. It has changed me as a human being and how I see and interact with the world. It is part of what makes diving so beautiful, that immersion in water brings us places that almost nothing else can. Even if we dive the same location again and again, it is never the same dive twice even if we were to staple the fish to the reef, because we are never the same person as the dive before changes us forever. So, we cannot have the same dive twice, no matter what. We are never the same person the next time through.
Diving is so special because it touches us so deeply. All of us who dive understand this to our core whether we “get it” consciously or at a subconscious level. For those who are contemplating beginning to dive, I would just say enjoy every moment as diving brings many of them. Big transformations are part of it, but often it is the littlest of ones that ripple through our lives too.
This is why what and how we think about diving while we are diving is powerful and needs to be considered. More than being considered, we owe it to ourselves to make sure we do the best we can with our thoughts because diving is so powerful. We have a duty to make sure that something so important and powerful is respected.
More importantly, it is just more fun to be good.
So, how do we begin our work?
The performance mindset begins with us. One of the things I love about diving is that we cannot hide from ourselves in the water. We all find our moments of truth in the water. Great circumstances bring big pleasures and change us, challenges and difficult situations tells us volumes about ourselves and further bring to our immediate awareness areas that we may have tried to hide from in ourselves. These can also change us for the better expanding our awareness and allowing us to be more adaptable after.
If we do not train how we think about diving, the effort to learn more about diving and being better is hampered. What I am suggesting is that our mental training is as important if not more important than skill mastery or taking another course. How we do these things matters as much as actually doing them. Execution is as important as accomplishment.
As I presented in my first post, we need to make sure we have a picture in our mind of what it means to be a great diver, an elite diver. We have not been presented with a simple well thought out snapshot of what this means.
This elite diver concept is so important because we will rise to the level of the vision we have for ourselves. If we do not have a clear picture of what is means to be good at diving, how can we have a hope to arrive at a point of something we do not understand or can easily picture? We can put 100 of the best instructors in the world in a room and we would likely have some common threads presented as to what it means to be good at diving, but it is unlikely we even share a common language about it. The diving industry does not paint a clear picture either. It is not about blaming anyone. It is about providing something that almost all other activities can easily provide. A clear, easy, simple sound bite style quick answer or someone to point to for a clear visual.
So, lacking any clear, simple, or easy answer, let’s take a look at what might be this undefined mystery diver, the elite diver. I think we can all agree that an elite diver should be in control of their diving at all times. This would include all that their actions impact or do not impact with all that is around them. So, it is not just performance, but how that performance creates or does not create issues or impacts on all other factors around them. For the most part, this level of control is automated or unconscious. Or you might call it intuitive.
This means that the diver is able to adjust for wave action, or current, or motion acting on them and yet still appear there is no impact on their diving. It might feel very different internally, but the outside shows no changes. An elite diver only deviates from ideal performance because they choose to. Rather that be because there is a need to affect control for other purposes, or to have impact on the diving environment, or to compensate for actions in the environment that will take the diver out of ideal performance.
The diver is in control as much as is possible while diving and nothing happens without a decision by the diver to do so. So, unideal performances are a choice on the divers behalf or a mistake. The mistake is immediately and naturally registered in the mind as out of ideal. This is looked at and address that dive or the very next one.
If we can build a simple picture of what we would look like as an elite diver and be very candid and honest with ourselves as to where we are or how far away we are from that picture, it is the base that will help us improve rapidly.
If we can see it, we will rise to our vision of what it is we are shooting for. That “end goal” becomes the guide and foundational image we carry forward to build our skill mastery upon. Rather than work on skill mastery and just hope we have a “happy accident” that helps us find our way to how to make it all work together.
It is a cart before the horse problem.
So, we need to work on how we think and the vision we carry forward with our diving. If we can internalize and clearly see what it means to be an elite diver, it will provide a road map of where we need to go next.
This can be easier to see than do, but that is the beauty of diving, you must do the milage to master the craft. You have to dive your way into the thinking and out of bad habits. It is the rituals and way we view where we are supposed to end up that create our diving habits. These need to be guided with this clear vision of how it all fits together.
So, how we think matters when we dive. We need to make sure that we establish that piece of video or vision in our head about where it is we are headed with our diving. Once we establish that, we need to make sure we stay aware when we dive to this vision we have established. The feedback loop continues forever, but becomes more automated with each moment of application.
I want to get into more detail about the breathing we should be doing when we scuba dive. As I mentioned in my first post, it is our first and most important foundational skill. Well, not that they are not all important, but pretty much everything in Precision Diving is based and results from how we breathe and the choices we make around that.
I mentioned the foundation of the performance mindset as well. I will be coming back to that in a future post very soon. I thought it would be a good idea to begin this more specific discussion related to breathing sooner rather than later. This relates to open circuit scuba breathing. Rebreathers I will address later. A few slight and not so slight differences there.
At my presentation at OZTek 2011 the vast majority of participants when I asked how we are told to breathe said slowly and deeply. When I asked, “Have any of you ever actually been shown what that truly means or been taught it or had it demonstrated to you, ever?” That moment is a good moment, perhaps many of you had that when you read the first post or you are having it now. That realization of hey wait a minute, really, yes, wait, HEY, it never happened. Fun to see that lightbulb go on for people.
If you are highly experienced you might find you are feeling a bit of resistance about now. Don’t worry it is fine. This too shall pass. It is not to indite the industry or wave my finger at it. I am part of it. I simply point this out because if we are not aware of it we cannot be open to talking about it. We think we know, we assume that since we have been breathing, for the most part since the day we were born and it is automatic, that surely we must know how to breathe properly. Well, we don’t, well unless you were trained how somewhere usually. If you already get it, great. Perhaps after this there will be some common language or structure to at least be able to more easily talk about it in the future. At worst, you might pick up a few new details. For the rest, you should see a decrease in how much gas you use while diving almost immediately.
I am not pretending that I am inventing most of this. I am just bringing a language and a structure to it that we can use to talk about it more easily. So much of this stuff I struggled with trying to make it come to life in my clients until I understood we were missing the common framework and language to speak from. It was like not being fluent in the same language and carrying on a conversation when there was no obvious common references to work with.
So, I bring this concept forward early in the discussion because it is so critical. Breathing is the metronome and cadence of our diving. I will bet that if you have ever had a not so happy dive, that when you think back to it, it is very likely that your breathing was not ideal. In fact, I bet that your breathing was all messed up. So, if our breathing is messed up, it is likely that the diving is not too far behind it.
Diving is a powerful thing. It changes you forever. Do we ever want to risk having such a powerful thing be a negative in our lives?
If we are aware of breathing and gain full access to all the confidence and control it can bring for our diving, you will look back and wonder how you ever managed to enjoy it as much as you do now. It is the most intimate and quickest way to make small and large adjustments in buoyancy, trim and help or hurt how we move through the water.
Think back to your open water course (beginning) and remember that we are told to move up a bit if we have difficulty equalizing our ears or sinuses. Generally, we are told to add some air to the BCD or swim up a bit. We are not told to use our breathing to focus on cycling through a more full lung volume. Or we are told if we begin to move toward the surface without wanting to because of a bit of positive buoyancy, we should let some air out of our BCD. Why not tell the diver to cycle breathing momentarily on the lower part of their lung volume? Of course, it is important to make the adjustments eventually with the gear. But, what is more accessible to the diver, their external kit or their lungs?
Effectively, if we learn to use our full lung volume and can control it, it can be like adding or removing five pounds (2 kg) of buoyancy far more quickly and controllably than waiting to find and fix the kit. With the lag in changes in buoyancy there is time to find and fix the kit if we can mitigate the issue with how we breathe. Rather than, especially the new diver or student diver who might not be automated with where to find and adjust their kit, having to make sure they are in correct position and have the correct bit in the right place. This more immediate control and ability to make more major adjustments will allow you more control and that brings with it confidence. There are of course limitations to how much we can affect change with how we breathe, but it is certainly more than most of us are aware of or has ever been actively mentioned to us.
The nice thing is that these types of minor corrections and getting the hang of things becomes easier because we can be less quick about it potentially. Instead of worrying that if we miss the correction a few times we will have more and more difficulty. We can use how we breathe to create that space where we can take a pause to think through what needs to be done correctly. We can mitigate the issue and with it be more likely to be able to address it the first time.
Breathing is critical and will be discussed many more times. Once you begin to master your breathing you will begin to see just how many ways it has impacts on your diving. As it becomes more automated, you will not have to think about it as much and the adjustments will also come without having to think about it.
This is when you have the appearance that things do not affect you like it does other divers. They will be thrown a bit by some surge or waves above and you don’t really move. They might find it is a bit of a struggle and feel like they have less control. We will talk about it in a future post, but as you evolve with the skill the levels of detail gets deeper and deeper. Like so many of the others things in diving, we are training new default responses. This is one of them, just like the rest.
Below is a piece I wrote for instructors about teaching breathing for scuba over six years ago. It never ran with the publication that asked me for it. While it is not geared toward the diver, it gets the details across and I think you will find it an informational resource.
Breathing for Scuba:
Lessons from those who only have one breath to do what they have to do.
Freedivers do their dives relying only on the breath they carry with them. So, you can bet they make the breaths leading up to a dive really good ones. In fact, freedivers actively work on how they breathe. The old adage in scuba of deep slow breathing is true, but only scratches the surface of what is involved. It is almost universal that breathing is not really taught in a scuba course.
Freedivers use deep breathing techniques prior to a dive to optimize the gas exchange in their lungs. They use their physiology to its full advantage to insure they have the maximum use of their last breath. Scuba divers benefit from these techniques while diving gaining maximum breathing efficiency and extending the duration of their gas supply. Unfortunately, the vast majority of scuba divers are never learning how to breathe properly. This becomes very apparent when diving with virtually any group of divers. Breathing remains one of the great under utilized tools of diving.
Simply put, the visual image used for proper breathing is to fill your lungs from the bottom and empty them from the top. Seems simple enough, however very few ever seem to master the technique or more appropriately are never taught the technique.
The proper technique is known as diaphragmatically initiated breathing. It takes advantage of lung physiology. It is important to understand a bit about the lungs to understand why how you breath is as important as breathing at all. All parts of the lungs are not created equal when it comes to gas exchange. Most divers breathe primarily in the top of their lungs. This technique reverses that. The bottom one third of the lungs is responsible for seventy percent of gas exchange in the lungs. This is why it is critical to keep the lower third of the lungs occupied with gas for as much of the breathing cycle as possible.
So, the next time you teach an open water course, spend some time teaching your clients to do something they think they already know how to do, teach them to breathe properly.
Have your clients begin to fill their lungs from the bottom first by actively extending their diaphragm out while not using the chest at all. Now, this is not the sexiest way to look, but it does allow the lungs to fill from the bottom up. Have them concentrate on just using their diaphragm to breathe with. This looks like a pooch in the belly moving in and out. Once they are able to just breathe from their diaphragm, have them add their chest to the inhalation about half way through the expansion of their diaphragm. Once they have a comfortable full breath they should pause in a relaxed way for a second or two.
The number one rule in scuba is to never hold your breath. This is not a forced hold of their breath, but rather a pause in a relaxed way. If a depth change were to occur the air would simply be exhaled. It is important to emphasize to your clients that they should never forcefully hold at the top of the breath. It should be relaxed enough to allow for any expansion of gas in the lungs to easily pass and be exhaled.
The next step is to extend their exhalation. This can be done using the tongue on the roof of their mouth. Freedivers use pursed lips, but that is tough with a regulator in your mouth to do. The diver should feel as if the gas is leaving their lungs from the top to the bottom. The ideal is to keep the lower lung inflated for as much of the breathing cycle as possible. Once mastered this new breathing technique will take anywhere from ten to fifteen seconds to complete.
When done properly, the diver begins to develop a breathing parameter. The concept of a breathing parameter is an important concept to introduce at all levels of training. A breathing parameter is the rate, depth and way you breathe while you dive. We need to optimize our BPs at all times when we dive.
When diaphragmatically initiated breathing is used in scuba, the diver does not need to change breathing parameter when experiencing changing workloads as there is no more efficient way to exchange gas in their lungs. Considerable work, time and effort should be used during all training to correct the diver’s psychological urge to lose ideal breathing when experiencing exertion. There is no reason to go back to rapid shallow breathing when faced with increased workloads as that is only going to use gas faster and make the diver feel worse and more starved for gas. This is mental training as much as it is physical training. We need to reverse the tendency of divers under stress to consume gas rapidly with the least efficient way of breathing possible.
This is a foundation of becoming a good scuba diver. There is no better place to introduce foundational skills than at the very beginning. It is important to establish this foundation and emphasize that your clients should go back to this as soon as they realize they are out of ideal breathing. There are times when all divers leave ideal BP. Teaching divers to correct bad performance is often more valuable to them than just learning the ideal performance. The easiest way for someone to regain ideal breathing when breathing rapidly is to extend exhalation.
The active component of our breathing is the inhalation phase, exhalation is actually the relaxation phase of breathing. So, it is very important to minimize any effort while exhaling. Regulator quality has a great deal to do with exhalation resistance more so than inhalation effort. So, to regain proper BP, it is better to begin to relax exhalation. Teach your clients to begin to extend their exhalation on each breathing cycle. As they begin to relax, they will regain their ability to use ideal breathing. It is generally a good idea to have them stop their activity while they regain their BP.
Now, there are times when scuba divers want to not be in their ideal BP. This occurs when adjusting buoyancy and controlling tight hovers. Extending inhalation or exhalation is still fine. Just make sure that your clients do this still filling from the bottom and emptying from the top. Teach them to not hold their breath to hold position but to maintain a tighter range of lung volume while doing so by inhaling sooner and/or not exhaling completely.
As divers gain experience and rise in the ranks, proper breathing becomes even more paramount. At advanced technical diving levels the maintenance of BP can mean the difference between life and death. So, work with clients from the beginning to help them establish the breathing foundation needed for them to be confident and effective. Freediving provides a great training ground to continue to work on ideal breathing.
I hope that helps shed some light on using breathing to improve your diving. It helps a great deal to work with someone that can help you to learn to control your breathing muscles and work with you on breathing. There are many activities that utilize proper breathing techniques and will lend to improving your breathing for diving.
I spent the two days after Ag’s service being hosted by John Dalla-Zuanna and his family. They live on the edge of a reserve and that reserve had kangaroos in it. Being from elsewhere, that was pretty cool. I am savvy enough to know that Australians do not usually have kangaroos in their backyard, but John does. Cute looking, but I knew if I got too close I would get my butt kicked.
Turns out John has been cave diving for a very long time. So, it was fun to get to hear some of the old stories about his pilgrimages from Australia to Florida to dive back in the day. Evenings were filled with stories of Sheck, Woody, Wes, and countless other founders of the Florida cave diving scene. His first trip went long enough for him to buy a car that Sheck set him up with. Only problem was that he needed a US license to get the car insured. Adventures at the DMV were almost as rich as the cave diving.
John has not stopped doing big dives since. He has continued to work and push some of the biggest projects in history both in cave diving and wreck diving. He was part of the dives on the RMS Niagara. He also has dived deeper into a cave than almost any anyone as part of the dives at the Pearse Resurgence.
He is also one of those engineer types that gets an idea and will actually build it. He is also quite a cartographer. With some of the coolest computer aided cave mapping I have ever seen. It was good times to get to know him better. Our paths had almost crossed over a decade ago when it looked like I was supposed to go to Australia to run some training. That course never happened. But, we finally met at the last OZTek in 2009.
We talked late into the evening sharing stories and comparing notes. I have to thank John for the hospitality he and his family provided me. It made the trip better.
It got me thinking about why we cave dive. That was brought up a lot at Ag’s service. Why would someone do such a thing? The reason is individual and no one answer will due. It is for each explorer their own motives that drives them to push forward or not. It is something very different than most people experience. For me, it is cool to see or be where no one has been before. But, that is not the main thing. It is really where I go in myself when I am doing it that is the thing. Those moments that are hard to explain except to say it is just you and your own decisions. Where the journey takes you inside is almost more important than where you go on the journey.
In 2000, I was diving as part of the Cambrian Foundation expedition where we found a system we named Sistema Camilo. We named it after an elderly gentleman that owned the land across the street. He was well into his 80s when he joined us in the jungle to help us find a hole in the ground. With machete in hand, no less. He has since passed away.
Map of Sistema_Camilo
After a particularly eventful day of diving on the 2000 expedition, I wrote the following piece. In the moment, it was where my mind was and part of why I cave dive and explore.
Moments of Discovery
It is moments like this when those who live it can only understand what is experienced. But, I shall try to make it come to life here.
So few are lucky enough to be friends with people where you literally place your life in their hands. As cave divers we have that privilege. As with any privilege, there is a cost. The reverse holds true. For if my life is in another’s hands, their life rests squarely in mine. Someone else’s mistake can kill me, but just as easily mine can kill both of us. A tangled web that binds people together like so few other experiences can. I have heard that going to war can bring about similar circumstances. Not that cave diving can compare on the strategic level. However, I think on an emotional one the two are very comparable.
For some, the cave diving as war mentality holds truer than seems clear. They lay siege to the cave. Doing battle with every inch of passage. Fighting to gain ground and retreating to gain advantage or reassess plans and perspectives. This may work for some, but it seems to counter the deeper connection that comes from this baptism by water.
The earth is open. Passage laid down by water tens of thousands of years ago, decorated and sculpted. Now packaged under a veil of the very water that created it. The passage is not an enemy to be concurred or seized. Rather, the passage is given to us by the very earth and water that created it.
The gift is not given freely. Almost as if the gift itself grants permission to the receiver. The cave makes the terms of the exchange. Really, the cave could care less. As humans we have a need, an almost habitual obsession to attribute human character to things we find hard to understand. We cannot grasp the totality of something where changes occur in thousands of years rather than in months. The cave does not have an emotional attachment to the outcome of exploration. It, the cave, simply is. The cave continues to do what it does. Uninterrupted and unnoticing of our activity.
We, humans, are the ones with emotional attachments to the outcome of exploration. In our emotional state we do receive great joys and great heartaches at the hands of a very unemotional master.
Many choose to avoid such mind-bending thoughts by simply staying home. This forms an artificial world by which people can introduce an element of control into their life. A cocoon of sorts. But by hiding from the world are we really living or truly successful in life? We try to feel powerful. When faced by something (the cave) that literally carves holes in solid rock and decorates it in the process, most people lose any false sense of power they may have. We are powerless on that level. Oh sure we can drill, dig, carve and blow holes into the ground, but we will never be able to match this splendor.
When faced with such an awesome perspective, you can put forth the delusion that you have a hope to lay siege to such a creation. But when we do we build a glass house. The magnitude of the truth overwhelms us. The true nature of the gift is not in the cave, rather it is in what it allows us to experience in ourselves. The gift is perspective, appreciation, the freezing of time, scope of the universe and our short time here.
Do you think a fruit fly would worry about whether it would get a vacation next year (assuming, of course, a fruit fly was able to think)? Probably not. They only live for about a month. In terms of the cave, we do not even match the life of a fruit fly.
In sharing with us this experience of the cave, we get a rare glimpse into time itself. We are here for such a very short time. The gift is that realization. You do not have to cave dive to receive that gift. It lives in all of us. Just paying attention is the only price. As cave divers we just get reminded more often.
I guess perspective is not easily molded. Advertisers would have a much easier time of it if it were. But, this crazy activity would not be possible without other people. The exploration process requires people. From talking to local landowners, to searching through jungle, to huffing equipment in for a dive, to diving in teams, to plotting data, to publishing the map, it all requires the cooperation of many people.
We miss human connection in the modern world. In fact, we are really bad at it. That is why most marriages end in divorce. When we place so much into the hands of so many we learn how to make it work. The prize for all involved and all gain equally is a connection with other people.
I think that is what makes this and war so powerful for so many. Because by its nature, they both force us to relate and connect with other people from a gut level. Which only issues of survival seem to instill in people.
Connected to all of these benefits is one that is connected to the cave. That is the water. For us water is life. While, we are not adapted to breathe it, water is necessary for our existence. With that necessity comes a certain excitement with trying to figure out where it wants to go. That path is critical to our continued access to this necessity for our life.
Having the privilege to try to chase that is an awesome one. Because the chase can be so exciting. The discovery is nice but the process of reaching it so much sweeter. For it is not the final connection, it is the passage we swim to get there.
That passage is laid out before us. Often times we make many wrong turns before we find the right one. That connection simply leads to more passage. Perspective of how it all fits together is helpful, but the strongest joy lies in that moment. The moment of connection or discovery or both. When it all comes together, it can only be called magic.
Like the explorers of old, we do not know what will come next. There was a time when the map stopped and beyond what was known was filled with ideas of fanciful creatures.
From here there be dragons.

Temperance: moderation or self-restraint in action, statement, etc.; self-control. Dictionary.com
I flew down from Sydney to Melbourne today to attend the service for my friend Agnes Milowka who died cave diving a few weeks ago. She had been one of the up and coming stars of the sport. She was very accomplished in a short time. She was one of the more enthusiastic and driven divers I have known. You can visit her site here.
Agnes, or Ag as many of us knew her, I met in passing at some show or conference a few years ago. It was two years ago at OZTek 2009 where I really got a chance to meet her. We were both speaking, her about her latest cave diving adventures in Florida (I enjoyed that she would present on her diving in Florida or the Bahamas in Australia and on her diving in Australia in the US) and me on freediving and lessons from technical diving for recreational divers. Neither of us had our presentations completed. Not such a surprise for me as I tend to get these things together late. I can speak on really anything, so it is easy for me to wait so I can decide what directions I want to go for the audience I have. For Ag it seemed kind of the same.
We happened to be sitting next to each other in the speakers room that day. Each of us wanting to make a dent in our slides. We would get bored and begin to chat. Any distraction is a good distraction when it comes to these things. She had seemed a bit nervous when she sat down next to me. Tough not to notice the energy from that girl and it was clear the nerves were related to her talk. Me being me, I asked her what she was nervous about. She wanted to get her talk just right for her adopted homeland audience.
When divers get together there are always stories. It is pat of what makes diving so cool. Generally, when divers are around cave divers the conversation relates heavily to what can possibly have us desire to do this or have you ever been scared and the like. The conversation is different when both divers are cave divers. There is an understanding of all that already. So, in a strange way that mutual understanding leads to picking up conversations more immediately and generally go places with those conversation more rapidly than you would with others.
The day progressed, one of us would pop out to see a speaker or grab some food while still working away on our presentations. Throughout the day we discussed many topics and how we dealt with many of the things faced while diving. I will save the details of the conversation to myself. But, I found she was a deeply driven and motivated woman with a strong desire to learn as much as she could at every chance she could. She was good. Perhaps almost too good.
Ironically, my last conversation with her was over lunch at another meeting last year. She had told me about the cave she was working in Australia and what she had been finding there. This would turn out to be the same cave she died in. Also at this meeting, I spent a lot of time speaking with Wes Skiles. He was a mentor to Ag. Both are now dead. Perhaps I need to check my karma.
I am not going to try to judge her actions on the day of her death nor do I really even have that right. She knew what she was doing and was experienced. I will defend the right of anyone to make almost any decision for themselves, especially if they are qualified and experienced to do so. How her life ended is not what matters, the life that was lived is what is important and what should be remembered.
But, I am going to use her memory to drive home a very important aspect of Precision Diving. That of temperance. Temperance of time. It is not for me to try to figure out if Ag went too far too fast. She was driven and wanted to have an impact. She did have impact on everyone she met or knew. That was very clear from everyone at the service. What her psychology was on that eventful day is only known to her.
Psychological aspects of Precision Diving are for a future post.
Trying to relate exploration diving to the average recreational diving is like trying to compare Formula One racing to a drive to your corner store. The experiences and the risks are completely different and the necessary components to make either possible just cannot be related to each other. But, it is not to say that we do not learn a lot from Formula One racing that helps car manufacturers make better cars for us to drive everyday. So it goes for diving as well.
Wanting to get better or go a bit deeper or take the next course in recreational diving is not likely to end poorly as training and experience are great things. Diving is a milage game. You have to actually get out and do it to be better. Improvement comes with time and respecting that time is critical to being a precision diver. Temperance to know you need to walk before you run and get the dives in, in a progressive and thought out way is a corner stone of our efforts. Milage matters. We just want to make sure they are good miles.
The great thing about diving is you cannot hide form yourself in the water. So, you learn to face your anxiety and fears as you go. You also find your greatest passions and joys in the experiences along the way.
Temperance is also about respecting that you need to work on the mindset of a precision diver for it to become an automated thing. When we train for diving in the beginning, we are spending a lot of time on skills, but we are also retraining the brain in new default responses. If something were to happen while we dive, we stop, breathe, think and act. This is in contrast to the engrained response most of us are born with when faced with a problem while underwater. The engrained response is hold your breathe and fight for the surface. That old response is replaced with a new one of not panicking and not bolting for the surface while we hold our breath.
It is very important that we respect that it takes time to achieve this change in our default responses.
Precision Diving has its origins in technical diving, but applies to all diving. It is much easier to approach diving in the best way possible from the first opportunity than to wait only to have to fix bad habits. It is a system that can be introduced at any level in diving because its foundations are universal and apply to all levels of diving.
I like to say that if you want it to become habitual, you must create a ritual. Or create a ritual for it to become habitual. This also takes time. A habit, good or bad, is just a behavior we have repeated over and over again. These patterns lead us to our habits or what we tend to do. It also helps us become automated in our motor responses. Like driving that car or like being able to use diving for other things. Perhaps have a camera in your hands and still be able to dive with ideal performance. Time and repeated experiences are what do this.
Precision Diving requires temperance and patience to make sure that the correct rituals and pattern are established early to ensure good performance. The nice thing is, even if you have no agenda on the bottom, it is always more fun to be better. It is why we say be better this dive than the last, better the next dive than this one. Practice temperance while you dive and evolve as a diver. Gain experience in measured steps and when you change something, work up those changes from the pool to the ocean and then and only then take them deeper or further. The pool is your best friend and is the playground where we work up any significant changes to our diving or kit, not something that is only for new divers at all.
Execution is always more important than ambition. In the end, we dive to have fun and it is more fun to be better and feel confident in our diving. Precision Diving will take time to take hold in you and it could be a year or two before you “fully get it”. But, you will if you stick with it and pretty quickly you will not need to actively think about all of it. Respect that it takes time for us to reach unconscious competency and for new responses to become automated. Temperance.
