Question, who is stopping me from downloading VPlanner, sling mounting a couple of AL80s and diving to 200+ feet off Monastary Beach (depth 100yds off shore is over 2000fsw, on the west coast you don't need a boat to get really deep).
You guessed it -- I do. The same persion that keeps me from skiing black diamond runs (I am a horrible skier, I would have a better chance surviving a 200' dive then I would a black diamond run).
My point, and I believe we are in agreement on this, is that training is about passing skills and knowledge from one person to another. One of the most important pieces of knowledge that a scuba instructor "should" pass along to their student is a clear understanding that this sport has a level of danger involved and that their training had limits and that they need to practice within those limits until they receive more training (regardless of certification level).
There is more than one way to progress in any sport.
You can buy more training, yes. Or you can learn on your own.
The latter is often more rewarding, it is always more personal, and it usually leads to better comprehension of what works and what doesn't. It can also get you killed or hurt, of course - but then so can "instruction" where it doesn't "sink in" because of style differences or other issues.
It is entirely possible to teach yourself how to dive. People have done it for a LONG time. "Certification" is relatively new. As I've noted here, one of my regular spearfishing dive buddies is self-taught, and while he may be kinda ugly underwater, he sure as hell brings home the fish. He has no logbook - I suspect the reason being that he has no idea how many thousands of dives (literally) he has under his belt. He does deco too, sometimes, when the chase is worth it and the gas plentiful. I've yet to see him have a problem underwater.
Now would I grab some 'Mix and head to the Doria? No. I know that I'm not ready. I may never be ready. But should I be prevented from doing so, if I'm insane enough to want to?
No once again.
What worries me is people who take an AOW class and suddenly they're a "deep diver." Narcosis is real. Not being able to stop, think and then act underwater is real.
Not being able to deal with the FACT that underwater there is only one real emergency - being out of breathing gas - when the water turns brown will get you hurt or killed. The "big deal" about truly learning to dive is realizing that all other issues are not reasons to have a freak attack underwater; they are all issues to work, but are not emergencies. There is only one emergency - OOA. Everything else is a situation. Once you truly understand this and get past the "fight or flight" reflex, the rest is logic. The environment you intend to dive in defines the rest of the game - what you must take with you, how you must dive, when you must turn - all in pursuit of insuring that the one true emergency - an OOA - does not occur.
So far, other than my OW class, which actually taught me a few things, every other certification card I hold has been a joke. AOW and even Rescue. The only useful part of Rescue was the requirement to retake my CPR/EFR class, which has changed somewhat since the last time I had it (a long time ago!) - specifically, I got to play with an AED - not that I couldn't have figured it out (the silly thing TALKS to you!) without the class.
I don't claim to be an "uberdiver" or an "expert." I never will - I'm not the type of person that a Sheck Exley was, and never will be. I have no need to see "the end of the line", or to see how deep I can go and return still breathing.
I do know how to dive a drysuit, and do so. I taught myself; I know how to recover from a runaway ascent, a feet-up profile, and the emergency means of stopping both - hint: you'll get COLD! I do decompression diving - again, taught myself. I studied a lot, started with very, very light exposures, and still, by many people's standards, do "weenie" deco - so far, so good. I taught myself how to dive doubles, how to rig the hog harness, how to route and deploy a 7' hose and WHY you want one, how to rig my own bungied backup, neutral buoyancy, proper trim, and how to kick so as not to roil the water - including backing up, which I can kinda do. I learned along the way that there are places where you'd like to back up
but can't due to limited leg room too! (guess how I found THAT out!
)
I also taught myself how to spearfish, where to shoot, how to string 'em and what NOT to do in that sport. Some of those lessons were taught underwater by the fish.
I taught myself how to penetrate wrecks and get back out. I read much material on penetration diving, the cardinal rules, and why they're important. Did a lot of thinking about all that. Did a lot of "weenie" penetration dives where I still could see light, and knew where the exit was. Going 300' back into a cave - or ship - doesn't bother me now. I'm well aware that if I screw up I'm dead - so I endeavor not to screw up. So far, so good - but I've taken it SLOWLY rather than quickly, and don't break the rules. The rules are all designed to do one thing, really - insure that you don't have the dreaded OOA.
I've taught myself how to blend mixed gas, how to O2 clean my own gear, how to rebuild a regulator, and how to run my own fill station. I have neither blown myself up or had a failure (yet), so I must be doing SOMETHING right.
It isn't that hard, IF you pay attention, study the available material, do things gradually rather than tackling them head-on all at once and take your time.
After all, you DO like to dive a lot, right?
So what use are the cards?
None at all, really, other than "buying" admission to some places I'd like to go. Its a tax system, its corrupt, and it needs to go away.
