MikeFerrara:I'll give you a direct association. Two of the deaths at Giboa this year are thought to have been caused by free flowing regs. Many of the rapid ascents/injuries/ems responses there in the past have started with free flows also.
Now lets look at how that relates to agency standards. Some agencies don't teach free flow management at all. PADI is actully one of the ones that does require it. Hhowever, it isn't required that it ever be done in a diving context. I think that if you go watch a bunch of classes you'll see that students usually practice it while solidly planted to the bottom on their knees.
When it happens on a real dive we're usually midwater and controling your position while managing a free flowing reg is a completely different ball game. Very often the result is an uncontroled/rapid ascent. Some of those rapid ascents result in injury.
I'll give you another direct association. Several incidents at Gilboa over the years have involved AOW students diving with an instructor on a "deep dive". We've been all over the minimal requirements in the OW standards especially as they relate to actually having to dive midwater, buoyancy control, trim ect. Now lets look at the fact that the AOW deep dive may be the students 5th lifetime dive. The point is, we demonstrably have a student who has never been required to demonstrate that they can dive well shallow and they can be doing a 100 ft training dive in 40 deg water. Lets throw one more point in there and that is that you can become an instructor only having done one dive below 60 ft (the instructors own AOW deep dive). So HOT DOG, the instructor and his/her student can do their first 100 ft dive together. Now, should we be surprised that we DO see AOW students getting hurt?
Lets not stop there though. The AOW deep dive usually consists of kneeling on the bottom and doing a puzzle and then maybe a shallow tour. No real deep diving going on here but now the student has this AOW card. That AOW card and filling out a "deep dive plan" gets them a ticket to the deep side. They may actually even think they are qualified and prepared. According to the text they are right. That AOW deep dive (and it's prerequisites) has to be the biggest travesty in all the diving world.
Now we've sort of gone full circle and lets ask what the training background was of the two divers who got killed when they're regs free flowed. I don't really know the answer but I'd be willing to put up a modest amount of money that says my first guess wouldn't be very far off.
I am speaking solely about this incident, no others. I'll give it to you that the first 2 incidents were a result of poor judgement facilitated by inadequate equpiment.
I'm a product of PADI and have gone past that scene now, I see where things can go wrong when people dive beyond their training. It's horrible to watch people in singles go over to the deep side in Gilboa.
