CCR Myth #1

I gave a presentation at OZTeK 2015 entitled " Is Our Training Failing Us? Developing a Culture of Sustainable Safety Practices for CCR"
Since OZTeK, I have been contacted by quite a few people requesting that I post a copy of my presentation here on CCRX. Because the presentation is about an hour long, I thought it might make more sense to post a different segment of the presentation every two or three days. That way, people can bat around the ideas, discuss the validity of my various points, and offer any contrasting points of view. Each segment of my presentation starts with what I consider to be a specific myth within the CCR industry and community. I have identified 22 different myths.

Let me also mention, that the material in this presentation is simply my opinion and does not necessarily reflect the views or protocols of any particular training agency or manufacturer, nor are my observations intended to be critical of any particular agency or manufacturer.


Myth #1 - TRAINING IS PRACTICE

*I want to start off by saying that I’m a huge proponent of consistent training at every level. Find the best, most qualified instructor you can find at each level and make sure that you enroll in a class to learn the basic concepts and skills. However training does not ensure mastery. Practice ensures mastery.



The Great American football coach Vince Lombardi once said: "Practice does not make perfect. Perfect practice makes perfect!"
*
Too many times I’ve had students show up to take advanced CCR classes only to demonstrate a lack of understanding of basic skills and virtually no ability to complete the skills. Skills like dil flushes, bailout procedures, manual operation and so on and so forth. Basic mod one type stuff. Believe it or not, this is more often the case than not! Do I blame their instructors for this lack of mastery? Perhaps in some cases, but in many cases, the students have simply forgotten the skills or become so unpracticed at them that they are virtually worthless to the diver. I often read divers discussing complex CCR rescue scenarios on the on-line forums in heated debate, to solve extremely rare and almost non-existent problems, yet they have virtually no real life skills when it comes to the basics. I have to assume that they were trained on them at one time, yet due to short class schedules, or one-off parroted demonstrations to their instructors, they are deemed to be fully ready for the next level! What a load of crap!

Mastery comes through repetition. Perfect practice makes perfect performance. Slow down, repeat, evaluate, adjust. Repeat, evaluate, adjust, Repeat, evaluate, adjust. This is how a trained professional musician or a professional athlete has acquired mastery of a skill. And just like a musician or athlete, if the practicing stops, the skills degrade and at some point, the musician, the athlete or the diver is no longer able to perform at peak performance.

John Stockton, one of the most famous and most prolific point guards in NBA history was purported to have shot a minimum of 1000 free throw shots per day, year round in order to stay at his high level of excellence. John Coltrane, the famous Jazz Saxophonists, spent 8 hours per day practicing scales! Not playing jazz, but practicing fundamentals!

In my opinion, a student should not progress on to the next class level until he has mastered the skills at his current level. Mastery comes through repetition. Repetition does not come through more training. We train so that we understand what is expected of us and for further evaluation so that we can gain the skills for self-evaluation.

Training:* Where a student is taught how to do something by an instructor.
Practice:* Where a student repeats what they’ve been trained to do until they can do it automatically, or without thought.* It becomes a conditioned response that bypasses the parts of the brain that are most paralyzed in extreme stress situations.

Training*is when you watch proper technique and try to duplicate it until the instructor says, “you’ve got it” and you move to learning the next technique.
Practice*is when you repeat that perfect form at various speeds, consciously paying attention to every detail, until one day you wake up and realize that you can do it perfectly, automatically, and FAST, without having to think about it.

Myth #2 coming in a couple of days!

I agree with everything up to the fast part. If cave training and cave diving taught me anything its that fast is never: a) needed and b) its almost always counterproductive. I don't think there's anything about CCR diving that requires speed either honestly. Proficient divers tend to be efficient and naturally quick. But speed should never be stressed in classes or practice IMHO.
 
Great myth buster Randy, as I state in my Survival Guide To Rebreather Diving (www.haynesmarine.co.uk / downloads):

Behavioural researchers have determined that it generally takes twenty repetitious days to turn a skill into habit, you absorb only 25% of what you are taught, an additional 25% of the information provided is assimilated through later reading and review during the instructional period and the remaining 50% of what you are taught must be rediscovered through your own experience. Place this into the context of a typical five-day rebreather course and you can begin to appreciate the limitations of such a course and the end product, i.e. the newly certified rebreather diver. Rebreather training curriculums provide the knowledge and skills needed to get you safely into, and more importantly out of the water when faced with a variety of emergency scenarios. However by the end of a five-day rebreather training course, that typically incorporates eight to ten hours of dive time, no skill has yet had time to become a habit and only 50% of the instruction has been assimilated. This leaves a large competency gap that must be bridged by the newly certified rebreather diver post training. To limit exposure to potential harm, this must be undertaken in controlled stages and may be considered an apprenticeship. When everything is going well, rebreathers are easy to use, deceivingly easy, not so however when they fail. Post-training over confidence is typical often leading to diving beyond current ability. Therefore grow your experience gradually and continue to practice emergency response skills. However, regardless of your rebreather experience, personal development is important to all rebreather divers, new and old, so continually study and in particular learn from others mistakes. Unfortunately many an experienced open circuit diver during the early stages of rebreather diving have confused confidence with current ability and as a result never survived long enough to serve out their rebreather apprenticeship. Don't fall into the over confidence trap.
 
Thanks for the post.
What would you say to a diver showing up to a MOD2 class and lacking the proper skill? (TDI had a great blog post on this recently: Are you ready for Trimix?)
"Sorry, can't go on with the class until you show up with a Fundies cert"?
Or would you require in some way or another (how?) that the student shows proof of the minimum skill set?
I am lacking those skills mentioned in your post and the blog above, and even though my MOD1 instructor mentioned to me classes he was teaching, I know I am not ready (as clearly demonstrated during a fundies class I took recently) and I told him so.
But then, I know a diver who rarely dives and is already MOD2 and planning to go MOD3.

There is some instructor responsibility, but there is also personal responsibility.

Looking forward to read the next installment.
 
My point with this is that by performing repetitions at a high level (perfect practice) the diver is able to respond quickly and efficiently to various issues without confusion and delay. This is not to imply that the diver shouldn't approach things methodically. Think about how it works when you are driving a car. If another car pulls into your lane, you efficiently and quickly respond because first of all know what the correct response is and secondly you are able to respond efficiently because you have driven a car every day for years and the repetition has given you a high level of skill.

I agree with everything up to the fast part. If cave training and cave diving taught me anything its that fast is never: a) needed and b) its almost always counterproductive.

Right on the money Paul!

Randy,

Thank you for starting this thread, I'm looking forward to the next segments as well as the discussion that it brings :)
 
These are great questions.

First of all, I would never allow a student to enroll in a class who does not hold the prerequisite training levels. In other words, if someone desires to enroll in a Mod 3 class, the prerequisite among other things is Mod 2 cert. The problem is that in many cases, the prerequisite training level does not in and of itself accurately indicate the level of competency of the student. This is in no small part due to the lack of "perfect practice". We have way too many students who feel no responsibility to practice and repeat skills on their own until they have mastered the skills at that level and are ready to move onto the next level. Additionally, we have way too many instructors who for numerous reasons are reticent to send a student home for remedial practice or alternatively work with the student to help prepare them for the next level. I will address this further in one of my next CCR Myths! Stay tuned!

Kudos to you for having the personal integrity to so some soul searching, self evaluation, and self discipline to not want to jump from course to course without the proper preparation.

Thanks for the post.

Hi Randy,

Thanks for posting. Great post. Cross training with different instructors has helped me become safer in the water.

Best regards,
Chett
 
Thanks for posting Randy! Great reminder to get back to diving basics .... check/practice skils on every dive...

My only "merit" is to keep reminding myself about the ultimate consequence of unknowingly putting myself in a situation outside of my competence.
You would think everyone would have this self-preservation instinct. But the fact is that each dive survived without any problem or even warning breeds complacency. I wouldn't call that overconfidence, simply ignorance or withdrawal in the background of a lurking danger, a blind spot in our conscience.
I have to force myself to remember this each and every time I jump in the water, as well as debrief myself as well as I can after each day of diving.
It's a learning curve but testimonies and discussions such as those found on this forum are a great resource to keep focused.
