A diver should be able to move through the water using their fins as the exclusive means of propulsion to increase efficiency and minimize the impact to the environment.
TDI Diver News
Fortunately, there is a way you can discover whether CCR diving may be for you without ever having to make that investment. It’s called the TDI Rebreather Discovery experience.
There is no fluff when it comes to CCR diving. Each step has value and should be followed as prescribed. And that’s not just my opinion, it’s the best, safest and most secure way.
by Chris Richardson:
A few years ago, okay… close to a decade (I’m getting old) I got together with a friend to have him evaluate me for some new Instructor Trainer ratings for technical diving. I had a few choices of who I could get together with to be evaluated but chose this particular evaluator because he has a reputation of being tough, was a friend, and he and I hadn’t been diving together before but knew each other well from being in the dive industry. Frankly I wanted to see if I was up to it.
We met up very early over breakfast and discussed the day’s plans. After lunch, real students would be joining us and he expected me to teach the class, but first we would go over and jump in confined water where he wanted me to demonstrate drills and skills.
When we got to the confined water site I was told to bring not just one stage, but two stage 80’s and a 40. I was in twin 104’s and drysuit. In other words, fully configured (kitted for those of us from the commonwealth) for a full on multi-stage dive.
First we did a buddy check and S-drills. Then he asked me to demonstrate, while neutral in trim, at no less than 8 ft and no deeper than 10 ft, stage management and gas switching from back gas through all three of the stage/deco bottles. Anybody that has ever dived with me knows that I ALWAYS want to do a warm up dive or two before doing any teaching, big dives, or being evaluated. This day I was going in cold and to my great relief I had no great difficulty managing the skill and surfaced to an evaluator with a somewhat evil grin on his face. He informed me that that was “pretty good” made a couple small suggestion for improvement then told me to do it again… without fins on! I must have looked at him like he was crazy because he laughed and asked if I had ever tried it before. I said no, of course not. He then informed me that “all” his students have to and that was that. Well… off my fins came, I settled down to the required depth, got myself in trim and neutral with some difficulty and then started the gas switching.
Yeah that didn’t work out so well.
It was humiliating and I provided great amusement to my friend. When he stopped laughing at me he informed me that I passed. I gave him a look and asked “WTF are you talking about?” He started laughing really, really hard and informed me that he does do the no fins but does NOT expect the student to do gas switches… then started laughing again. We had hadn’t fully communicated, he expected me to simply get there and get stabilized in trim and buoyancy, I thought he wanted me to fully do the earlier skill only without fins.
I then stated that, “I think I can do it, let me try again”. He raised his eyebrows and said, “Go for it”. I did, and I did. I took my time and if it had been a real dive with gas switches done so slowly I would have had to add another deco bottle to offgas the extra ongassing from how slow I was, but I did it. He was surprised and said he wasn’t sure he could manage it, he tried and he did it after a couple tries, we laughed and then the students showed up and we enjoyed the class.
I liked the skill as watermanship development for technical divers and use it when I teach (without the gas switch) but do tell people they should try it when they get comfortable with just the trim and buoyancy no fins drill. I also demonstrate both of these to my students to show it’s possible (I do only one stage however) I have had frustrated students protest that “the skill is stupid, why would you dive without fins?!”
Fast forward to two days ago.
Myself, and Edd Sorenson from Cave Adventurers in Marianna, Florida, were doing a fun dive together. The plan was he would show me some new cave in a well known cave system he had discovered and laid line in. The plan was fairly simple, we would scooter out a couple thousand feet with a stage, drop the stage and the scooters and go swim the new passage, come back, get stages and scooters, head back and deco.
The new section Edd found is pretty tight… not crazy stupid tight but certainly snug. We had to pay careful attention as to not stir up the bottom silt. There was one spot that was quite tight, almost crazy stupid tight. We reached the end of one line, turned around and Edd headed out with me behind, coming up to the restriction Edd slipped through, I followed and in the tightest spot it happened… I felt my left fin slip off my foot. I knew what happened. It’s a prototype fin that I had been testing, the strap was a little too big but not horrible and I knew that but wanted to dive the fin anyhow. The tight spot meant that I needed to stick my head and torso down, and then arch upwards to get through. Air went up my drysuit leg and into the boot and it popped the fin strap off. I couldn’t bend to reach my foot (okay, it was crazy tight there) so backed out to look for and put said fin back on. At this point the old saying “SILT HAPPENS” came true and needless to say, I couldn’t find it. After not finding it I came out of my silt cloud, showed Edd my “issue” and he decided to go get my fin… well that didn’t happen either. The good news, it’s not hard to move through low passage with one fin on, really. But as soon as we got out of the new passage into the main cave system which was much bigger the lack of a fin was MUCH more noticeable.
Using skills developed doing a silly drill, I retrieved my stage and my scooter, performed a gas switch to my stage, and started the scooter ride back. If you’re curious, scootering with one fin is easy at slow speed, not so easy at a medium speed and downright difficult at full speed on a good scooter.
The exit was uneventful; I was alternating between slightly embarrassed and quite amused I lost the fin. Upon surfacing, Edd ‘s first words were, “You made an event a non event”
We talked it over, I told him about the no fin skill, I admitted I was stupid to keep diving a fin I knew wasn’t a perfect fit and we discussed the event in the context of how we each could use it in teaching students so hopefully they could also turn “events into non events”. We also laughed about the fact that NOBODY but Edd or I would ever find that lost fin.
I’m writing this in the hope that other divers can learn to appreciate how important those safety, watermanship, and comfort skills we practice are. The place to fail a skill or a drill is in confined water while training, don’t short change yourself. Practice hard so you can dive easier.

As I look back on the days when I first started tech diving, two things come to mind that have had significant changes – equipment and logistics. There have been such dramatic changes in equipment it is hard to highlight them all. The early tech equipment was nothing more than standard equipment that was reconfigured to meet our needs, it was not specialized, light weight, easier breathing at deeper depths or made of special metals. And we certainly did not have rebreathers, those did not come ‘til the late 90’s. Logistics, on the other hand, has gotten better but can still be a little tricky. My tech diving started in the mid-Atlantic states of the US where there were several boats that would take us to deeper wrecks and allow us to stay a little longer in the water. We also had a hard time getting the gas fills we needed for the planned dives. Things have gotten better in this aspect but here is a list of things to be aware of if you are considering getting involved in tech diving or have recently learned to tech dive.
1. Boats – not all boats are created equal. Dive boat operators as a general rule rely on the number of divers they take out per day, pretty simply math – the more divers they take out, the more money they make. When boat operators take out tech divers they will usually reduce the number of divers on their boat (space for additional equipment) and stay out a little longer to allow for decompression or rebreather divers – this means you may pay a little more to do tech dives off of boats. This also means you need to speak with the boat operator and make sure you can do the dives you want to do off their boats. Mixing tech divers with sport divers normally does not produce good results.
2. I have to go! – tech dives are not always deep but they are almost always longer than your average sport dive. Longer dives means better exposure protection (even in warmer water) read: dry suit, which means no peeing in the water, or does it. TDI recently released two good articles on this:
The short version of these articles is, it is important to stay hydrated while diving and with hydration comes nature’s call. Lots of options to manage this situation so do your research before your next long dive.
3. I’m hungry – anybody that knows me knows I love my food and after a few hours in the water, I surface ready to eat! Diving burns calories and the colder the water the more calories burned. Tech diving from boats in many places also means longer boat rides, so getting back to the dock is not going to happen as fast as it does on sport dive boats. Bring along some good snacks or a sandwich to get you back to the dock. If you have a good snack on the boat ride back, you will be able to get started on the monster nap sooner.
4. Bring on the gadgets – not so fast. Tech divers are certainly gear geeks but they also tend to be minimalists and only bring what they need. A big part of what allows us to tech dive and stay underwater longer is minimizing air consumption; carrying more gadgets means not being as streamlined and increases air consumption. As you select gear, think about what kind of diving you will be doing, cave divers don’t need what wreck divers do and cold water wreck divers don’t need what warm water ocean wreck divers do. Also think about where it is going to go on your body or configuration. Too many things stacked on top of each other means you may not be able to access it when you need it.
If you are a planner or someone that likes to work through scenarios, technical diving is right up your alley. Plan out your dives, call the boat operators or local stores (if you can do the dives from shore) and find out what sort of support they can provide. If you will be diving from a boat, make sure you are clear with the operator what kind of dive you want to do and see if they will do it. Planning ahead is critical when it comes to rebreathers and traveling, not all locations support all rebreathers. Make an equipment check list and go through it before every dive/trip, with tech diving comes more equipment which equals more things to forget. Make sure that check also includes a save-a-dive kit, and that the spare parts now include the ones you need for tech diving. Plan ahead and have fun. A spontaneous tech dive can result in a spontaneous disaster. If you have not yet taken a tech diving course, consider signing up for the TDI Intro to Tech Course. This course will give a great overview of what to expect and what you will need.

The “What’s Your Life Worth?” series is not intended to scare people; it is intended to provoke thought and some introspective viewing as well as self analysis. The intended end goal is to increase safety and reduce the likelihood of an accident. Keep this in mind as you read the series because while specifics could be pointed out (there is an unlimited number of examples unfortunately) the illustrations are written in a broad swipe and I have been careful not to write them in such a way as to combine accidents as if they were one occurrence. In this piece I am going to get back to the very beginning of the decision making process, the first step, if you will. What are you willing to pay for a course?
Course costs and what is included in those costs run the gamut, but one element that does not is what it takes to make a proficient and competent diver at any given level. To create a proficient diver at any level four key areas have to be covered: the basics of learning which involve knowledge development, applied skills, repetition, and muscle memory. Sounds easy right? Well it is, but it does not happen fast.
Everybody learns at a different pace and in different ways, meaning: time is required for the instructor to figure how the student learns and to ensure short term and long term comprehension. Unlike some learning events, scuba diving also requires skill performances which add another layer to the learning process – muscle memory. Muscle memory is so critical to diving that it should be considered life threatening if it is not achieved. Here is a basic example of what I mean by life threatening. If a diver has not practiced releasing their weight system to a point where it becomes instinctive in an emergency situation, they could drown because they cannot stay on the surface or even get to the surface. Why do I use this as an example? Because it happens time and time again, divers are found lifeless on the bottom with their weight system still in place.
Like muscle memory, knowledge retention is needed in emergency situations as well. It may not seem important when you are learning but when you need the information to make a split second decision, that’s not the time to realize “I don’t remember my instructor teaching me what to do in this situation”. Chances are good your instructor taught it or that it was covered in the materials for the course but… was enough time spent on it?
So you may be asking yourself, what does all this have to do with the cost of a course? You have heard the old saying “time is money”, well the longer it takes to achieve and ensure academic understanding and muscle memory, the more money it will cost. See, unlike many other activities you will do in your life, scuba is based on physics and physiology, two things you can never escape or defy. A few other activities also come to mind: sky diving, high altitude climbing, and rock climbing. Here is the thing with physics and physiology, you don’t need to have a complete and comprehensive understanding of them but you do need to understand the basics because every time you get into the water you enter a new realm unlike the one our bodies are adjusted to on land.
Moral of the story, don’t look for the cheapest class, it could cost you dearly later on, look for the course that is going to give you everything you need to be a competent diver at whatever level you are working towards and that includes if you are just taking your basic Open Water Diver course. Talk to the dive center or instructor and ask them: how much time do I get in the pool? How much classroom time do I get? If the answer that comes back is, “We do as little classroom and pool time as possible to keep the cost down”, find another dive center or instructor. Find the place that tells you exactly what is included in the course and gives you the response, “As much time as you need to feel comfortable”.
Diving is an amazing sport that takes you to places that some people only dream about and you get to see things that few people have seen, but it is not without its risks and that’s what makes it exciting. Do yourself and your loved ones a favor – take a quality course which comes with a slightly higher price tag. Keep in mind though that higher price tags don’t always mean quality so make sure you communicate to the dive center or instructor exactly how you feel. If you are not comfortable or feel you are not getting the training you need… let someone know.
When the first “Technical Divers” started to evolve and climb out of the primordial soup of the sport realm, some would argue they were light years ahead of the modern day sport divers of today who desire to make the same journey. Without getting into a great debate on the evolution of diver education, the modern day student does lack something of the days of old. The lacking factor is the relentless requirements of skill set repetition until those skills evolve into muscle memory that develops into a diver’s ability to have “Recognition Prime Decision Making Skill Sets.” “Recognition Prime Decision Making Skill Sets” is simply a model of how people make quick, effective decisions when faced with complex situations. One must ask, what happens to the tech divers who have demonstrated basic skill sets in training where they meet the requirements of certifications but do not seem to be very fluid or competent later in the execution of the same skill sets in future training dives or when needed? One thing we must ponder is, what is the culture within the “Tech Diving Community” when it comes to currency and proficiency of basic tech diving skill sets? English Anthropologist Edward B. Tylor defined culture as “the full range of learned human behavior patterns.” “This may be the most intuitive principle of learning, traceable to ancient Egyptian and Chinese education.” Aristotle once commented that repetition in learning “is frequent repetition that produces a natural tendency” and “the more frequently two things are experienced together, the more likely it will be that the experience or recall of one will stimulate the recall of the other”.
“Our humanity rests upon a series of learned behaviors, woven together into patterns that are infinitely fragile and never directly inherited.” – Margaret Mead
Diving culture is a very powerful influence within our community that is constantly evolving due to technology changes, the better understanding of science when it comes to diving physics and physiology, and the educational/philosophical differences among divers/training agencies. The hard and fast influences of diving peers, traditions, and the trials and tribulations of the pioneers before us are also factors that affect the evolution of learned behavior. So in the diving community we have the cultural traditions of the past, sub-cultures (separated ideology), and the cultural universals (ideologies that everyone accepts as the norm).
“The effects of repetition on a single association of stimulus and response with the effects of practice on the development of skill, which is something quite different. In learning any skill, what must be acquired is not an association or any series of associations, but many thousands of associations that will connect specific movements with specific situations.”
So whether you are “Tech Diver of Old” or a “Newbie Wet Behind Ears,” there are skill sets we all can, need, and do desire to improve/refresh upon or hone into a better mastery of. These actions take repetitive practice. Whether it is learning to deploy an SMB, performing a valve isolation and shut down, or working through managing a diving emergency, there are four stages one must swim through in skill development:
- The Novice – Mastering a craft does not happen overnight.
- The Apprentice – Realize your personal limitations.
- The Journeyman – Where the real work begins. Practice makes perfect.
- The Master – Unconsciously competent
“To become a master at any skill, it takes the total effort of your: heart, mind, and soul working together in tandem.” – Maurice Young
The law of 10,000 hours
Author Malcolm Gladwell, in his book Outliers: The Story of Success, states that “you need to have practiced for 10,000 hours, or roughly ten years, to become a genius at something. It means ‘success’ isn’t necessarily genetic, socioeconomic or generational.” So if you find yourself as the “Novice” standing on the shore dreaming of the water, or on a boat sailing down the road to “Mastery,” it can be concluded that it is not always an easy journey to log the 10,000 hours needed for obtaining mastery of a skill set. Similarly, there is another inherent problem that must be discovered and understood. Once you master a skill set it can be a very fragile learned behavior and it requires a lifelong dedication to maintain or one may slip from “Master” to “Journeyman” in an easy fashion. A famous quote by Confucius, says, “I hear and I forget. I see and I remember. I do and I understand.” Research agrees, and shows that we retain in memory “10% of what we read, 20% of what we hear, 30% of what we see, 50% of what we hear and see, 70% of what we say, and 90% of what we say and do.”
So what skill sets do we tend to get lazy on as tech divers? One of the first we have to look at is equipment configuration. All too often we find ourselves getting complacent and dependent upon the diving gear we have grown to love and trust. After all, we have the best BCD that has a dual bladder, tons of “D” rings, and it is very rugged and durable so we can load it up with weights and the biggest steel tanks (so air management is never an issue either). All jokes aside we cannot cookie cut our dive gear due to the individuality of every diver. So on every dive a “Tech Diver” should put in some dry time preparation on the dive gear to make sure the integrity, functionality, and dependability is there. During gear prep it should be determined that the equipment will perform proper when needed. Similarly, the routing and placement of regulators/hoses, cylinders, and the attached accessories should be ergonomically appropriate for yourself and easily accessible for use and deployment.
Second is tech dive planning – pen and paper time are still a must if want to try and keep “Murphy’s Law” at bay. A lot of divers tend to fall farce to believing “I have a dive computer and it will tell me everything I need to know.” Knowing run times, dive & gas management profiles, the objective, and problem contingencies for a dive is still imperative. Complacency can be unforgiving. Another part of planning is gas analysis. As a diver at any level you should know what is in your cylinder because people do make mistakes. Analyze your own gas mixtures so you know!
Third is weighting and buoyancy. These topics are subjects that “Tech Divers” tend to get complacent about. After all we said we have the best BCD and it can handle it right? Remember, “When the crap hits the fan – there are no time outs.” Knowing the buoyancy characteristics of your diving ensemble is imperative because it does have a direct reflection upon you trim and air consumption, which can affect other aspects of the dive. Being able to control your ascent rate and adjusting buoyancy to neutral during deco stops are directly related to proper weighting and is something one can always strive to improve upon. Some other skillsets that tend to become rusty without practice are:
- Gas switching drills
- Valve isolation or shut downs
- SMB deployments
- Different finning techniques (frog, backwards kick, scissor)
- Equipment removal and replacement (stage cylinders)
- Navigation techniques
- Line reel management (tie offs, line retraction, entanglements)
- Loss/disoriented – especially in overhead environments
- Light failure
- Silt outs
- Drysuit emergencies (over inflation and flooding)
- Hand signals used by tech divers
- Dive rescue/prevention techniques (dive buddy monitoring, management of an unconscious diver)
An honest self-evaluation of yourself should be done, asking how you can become a better tech diver and member of a tech diving team. You should be open to evaluations by your peers because they may see things you do not notice about yourself. Finally, these actions as well as working with a TDI professional are all avenues one can employ in the journey toward the mastery “Tech Diver” skills. So how many hours do you have invested?

If, like me, you have read the last couple of TDI Newsletters you will have been following the discussion on the use of P-valves for Dry Suits, with two great articles, each written from a different perspective. The first was the domain of the male diver, with the usual highlights on size, strength and “stick-ability” (yep… us boys never change!), whilst the second was a fascinating insight from the female perspective. As an older male diver I never cease to be amazed at the lengths ladies seem to have to go to… to… literally, “go”. For guys it’s easy… we are traditionally like dogs – the world’s our toilet! But girls, in some aspects – you got the short straw.
Now, whilst both these points of view have been humorous and educational, they both took the position that there is really no acceptable alternative than to rip open a hole in your expensive, brand-new dry suit, have some creative and sometimes painful methodology of cementing a plastic tube from an intimate and sensitive part of your anatomy to some sort of valve, and spend hours in the water happily swimming around relieving yourself into the mighty blue within which you are floating (sort of like peeing into a very big bath if you ask me). Believe me… I, like probably most, enjoyed the imagery! However, and this may come as a surprise to many, there was an alternative long before p-valves, and there will be one long after you have hung up your last dry suit. It’s one of those “D” words divers don’t really like talking about… Decompression, Dehydration, and Diapers!
When we talk about Diapers, let’s make sure we understand a few things. Firstly, we are not talking about swimming around wearing elasticized plastic pants sloshing around in a bath of our own wee! If you want to do that please keep that in the privacy of your own home. Secondly, we are not talking about wrap around nappies with huge plastic safety pins and regulators that look like dummies (pacifiers) with honey on them. If you want THAT then you need to go back to an early issue of that great 90’s tech diving magazine AquaCorps (some images just will never go away!). We are talking about wearing Adult Diapers for comfort.
Okay… I appreciate that many people go “Yuck” and “Eeww” and suchlike when they think about using Diapers, or Adult Nappies if you wish. But, let’s be honest… not every man is built like Dumbo and most don’t improve in the cold. And as for you ladies, not everyone wants to share all their glory with a minimum wage beautician, most don’t like hot wax and pain down there and, to be real… how many of you really want to go through life looking like a pre-pubescent 8 year old (we won’t all be in our 20’s & 30’s forever and many European girls don’t even shave under their arms). So, let’s have an honest look at the alternative and some of the pros & cons!
Firstly, ”No-one wears those”! I am sure most of you have come across the Adult Diaper section of the Supermarket or Pharmacy. But have you ever wondered why they are on the shelves and not hidden away in some private unmarked cupboard? Simply… there are lots of people that use them. The global market is worth over $8 billion and it is growing at 8%, higher than any other toiletry market (including toilet paper!). Over 25 million Americans buy them every year.
Secondly, ”I’m not going to wear them”! HA! Boy do I have news for you! One in 3 women over the age of 18 suffers from some sort of sensitive bladder or incontinence. 50% of Seniors have some form of “urinary weakness” whilst 80% of people who wear adult diapers are female, mostly caused by the joys of childbirth. That means that unless you are either going to be childless, have babies only by Caesarean or be a grumpy old man with wet pants, then odds are that you are going to be visiting the Adult Diaper section of the Supermarket long before your days are through. So get over it!
Thirdly, ”I don’t want to sit in my own waste for hours”. Let’s break this one up shall we!
“…for hours”…! Not all of you are going to be Explorer Club Divers spending 3 hours decompressing from a 250’ cave exploration dive in the middle of Guatemala! Most of us are doing this for fun! Most of your students are going to be doing this for fun! Yes, we all want to channel our own inner Sheck Exley or Lloyd Bridges, but the reality is most boat trips, most cave dives, and most shore dives are a couple of hours max.
“…my own waste…”! Okay, Nappies/Diapers are there to absorb and contain our waste. (yes, you can get diapers for “number twos”, but as a p-valve doesn’t go there then we don’t need to either!). I am not too sure how many of you have ever picked up a baby with a wet nappy, however it doesn’t shower wee down its legs or have a pool of liquid inside. Diapers are designed to take the liquid away from the body and have it absorbed in gel type pads, leaving the body relatively dry. And if nappies weren’t a clean and sanitary option for their baby, do you really think so many moms would use them? And babies will use them a lot more than we ever will (well…for a few years anyway!).
Fourthly, ”But I pee SO much after just 30 minutes!”. My goodness… how much are you drinking before you go diving? It amazes me the number of people I see who are literally guzzling down drinks before a dive! What’s worse, half of it is either a Grande (or Venti) coffee or super-sized Coke! Have you people never heard of diuretics? These things make you go to the toilet! Add to that the high sugar drinks I see being drunk and you have to wonder whether they have ever heard of diabetes, let alone blood glucose levels!
So we need to talk about hydration. You pee because your body has produced excess fluid waste… the darker it is the more dehydrated you are becoming. We used to say 64 US fluid ounces per day, or just under 2 litres, equated to about a recommended 6-8 tall glasses of water a day. Now days, it is considered more appropriate to consider 6-8 cups per day, or just under 1.5 litres, in addition to a balanced healthy food intake. Your kidneys process about 4 cups an hour, so when you drink more what do you think happens to it? Right… hello bladder! The best method to hydrate your body is a constant intake of small quantities of water. Yes… WATER! Slowly! ALL THE TIME! Sip it! Don’t guzzle. This will keep your body hydrated and avoid excess fluid being directed immediately to your bladder! You will still wee… but your wees will be regular and smaller.
Yes, we dehydrate more when we dive… we all know this! Anecdotally it is said we dehydrate just over 1 litre of the body’s water (33 US fluid ounces) for every 88 cuft of dry compressed air we breathe. How precise that is who knows, but the principle is pretty right. Our rate of dehydration increases when we dive for many reasons, the dry air being one. So we need to compensate for this. The best method is of course by fluids while we dive (water filled camel packs anyone?), but having a well hydrated body before we dive is the most practical. This means being hydrated before we dive, not guzzling a gallon of caffeine before we hop in our dry suit and apply that nice tight weight belt or harness strap over our bladder! And if you are diving a CCR… what on earth did your instructor teach you about one of the benefits of “the warm moist air” anyway?
The net result is that if we are well balanced and hydrated before the dive, have gone to the toilet regularly and have not drunk copious diuretics, our wee requirements will be smaller. Now there is no problem with doing a huge wee in a diaper. Most babies don’t “control the flow”… they just let it go when they need to go! Well, using an Adult Diaper we need to learn the same. Don’t hold it in… just relax. The first time you feel like you need to go… go! This is how babies and all those incontinent mothers and seniors go… all the time!
Now, I know many of you are sitting there going “No Way”, “Not Me” and “It’ll spill into my dry suit”! So, don’t take my word for it… test it! Get hydrated, limit the coffee and sodas and go try it out in the shower! That’s how I was taught to get used to them… and that’s how I tell my students to try. If at first you don’t succeed, then just relax… and tackle it slowly. Oh, and if your partner asks why you are dressed in the shower in a nappy just smile and invite them in… their reaction will be priceless!
Let’s be honest, Adult Diapers are not for everyone. But neither are sticky condoms, lasered genitals and waxing! It is a discussion many divers need to have, and regardless of which side of the fence you sit on, it is one that every instructor needs to have a balanced look at. Of the many technical divers I have taught over the years, most of the ladies have tried them and many of the instructors now discuss this subject equally along with p-valves. As professionals, we have an obligation to be able to discuss both sides fairly. It is, after all, the diver’s choice!
Ohh… and lastly… don’t forget the benefits.
One – they are simple to use and require little “personal preparation” (and just because you wear them doesn’t mean you’ve used them)!
Two – they are available in most Supermarkets or Pharmacies around the globe!
Three – odds are you will have to use them one day so you may as well get used to them now!
And number Four – think of the potential of enjoying the Super Bowl without having to get up and lose your prime spot in front of the TV or having to move from your seat at the game! (Though, to be honest, I still haven’t convinced my wife on letting me test these applications!).
Safe diving… and a dry and comfortable one too!

There is no way to tell what your reaction will be during an emergency until you actually go through it. For all of you out there who believe that knowing CPR and going through a three day rescue course has you prepared to face some of the horrible things that could go wrong in scuba diving, you are incorrect. Let us be honest for a moment. The rules of CPR seem to change more often than some of us change our shirts. Many people believe that giving rescue breathes in the water while dragging someone out is simply a waste of time, and there will be someone there to tell you all about the things you did wrong even if you pull someone to safety. Despite the many opinions out there, there is no way to predict when something will go bad. The only thing we can do as divers is try to be as prepared as possible for when they do. Believe it or not, under the water is not a natural place for human beings to play around. So how do you keep your cool and stay calm during an emergency situation?
Man the Hell Up!!
There are certain moments in life where you realize the universe is giving you an opportunity to prove yourself. Seeing a loved one, or regular dive buddy, trying to hold onto life while you desperately attempt to help them could be just the opportunity for you to step up and knock it out of the park. While this is obviously not an ideal scenario, the world is simply not an ideal place. After all, no one made you get in the water to begin with. The adrenaline rush and sense of adventure is what drove many of us into diving in the first place. Without that basic need to push further and further, there would be no use in wreck diving or all of cave country. We could all be satisfied by seeing the pretty reefs at 40 feet. However, no one actually watches a NASCAR race to see people drive in circles. The wrecks make it worth it right? Just like no one wants to watch a soccer match for nine hours just to see people faking knee injuries every twenty seconds. The point is that because we push further into caves/wrecks and because we dive deeper and deeper, the chance for some really bad stuff to happen increases exponentially. Finding the inner beast to do what needs to be done may just mean the difference to someone. Dragging someone out of the water half dead may be better than pulling them out a few days later and trying to collect from your dive insurance.
Do Not Hesitate!
Once you make the decision to intervene with someone to help, you better not stop until that individual is safe, killing you, or dead. There is no room for a half measure when it comes to emergencies. Wrapping your head around this notion is necessary in staying calm in the midst of something chaotic. Once you make the conscious decision that you will not stop, everything else becomes easy. Either you will succeed or you will die trying right? Either way, no one has time for you to second guess yourself. If you were wrong and misinterpreted the actions of your dive buddy as a sign of distress, then fight it out on the surface or at the bar. Maybe they should not have been acting erratically while diving to begin with. When it comes to dive professionals, there is a big line in the sand it seems. When should a pro get involved with someone? What if that person is not my student? What if the other Instructor ends up hating me? Who cares? If someone is in trouble, or you think they are in trouble, then you should probably go ahead and help out. If someone sees me stroking out in the water, please send me to the surface and help me get out of the water. I promise that I will not hate you for ruining my dive. All of that said, DO NOT be the guy who has to stick their nose into everyone else’s business at every turn. There is still a learning curve in diving and some take a bit more time to learn than others.
What is the Worst that Could Happen?
So you may have found yourself in an emergency situation, and your mind is racing with all of the information you could possibly remember. Take a moment and think about this though; what is the absolute worst case scenario for you? I always tell my students, in a very matter of fact way, that “Josh is gonna be alright.” In essence, I will go through hell trying to save you but if it comes down to it; I will walk away and be just fine. Any time there is a diving incident, there are so many people who want to point to the Instructor or dive operation and scream that it is their fault. Whatever happened to bad things just happening sometimes? No one expects for a high pressure hose to explode under water 200 feet down or 7,000 feet into a cave, but it happens sometimes. Good luck trying to sue the Chinese guy who made it. Sometimes bad things just happen. Ironically, bad things seem to happen to the nicest of people. So when you are handed the chance to help out, think about how bad it could possibly be. Try to do the right thing and everything will be alright.
So basically, there is no magic answer to staying calm during an emergency. I would say that all you need to do is pop a couple of Xanax before your dive and you will be calm no matter what. However, there are so many things wrong with that. As long as you understand that the longer you stay in diving, the more likely you are to run into a bad situation; you will become more and more prepared. That does not mean that you should bust out the red cape and start a new superhero scuba trend. All it means is that no matter what, you should have a basic understanding of what is right and what is wrong. As long as you stay on the “what is right” side of things, a bad situation will work out one way or another.
