Otter:Or perhaps your postulation about new students being dependent on DMs is incorrect. For full disclosure, I am a PADI Instructor(right in Walter's crosshairs). At least in California, dive boats don't provide in-water DMs. So divers are dependent upon themselves and their buddy.
While I won't argue that the requirements for certification have decreased over the last 20 years ( I wasn't teaching 20 years ago), perhaps the requirements then (as a carry over from the US Navy design to washout candidates) were in fact MORE than what was required for recreational diving. If the statistics show that the number of deaths/injuries vs. number of certified divers (and presumably dives) has remained constant or declined, perhaps its because current standards are sufficient, if not less than 'the old days'? I believe that for recreational diving, making the sport more inclusive than exclusive is a good thing -- as long as safety has not been compromised. Statistics seem to indicate that is the case.
I think we spend too much time looking at the number of deaths and too little looking at the number of near misses and the cause of the incidents.
I was an active instructor and a dive shop owner. In the begining I believed everything I had been taught including that diving was as safe as bowling and that just about any one could dive with a minimal amount of training. The accidents that I saw and heard about (fatal and nonfatal) changed the way I taught, the way I dive and the way I ran my dive shop. Eventually I became convinced that the agencies had no interest in addressing obvious connections between the cause of those acident and what divers are NOT taught in entry level classes. Additionally they were unwilling to address the fact that so many instructors are masters at teaching very short minimal classes that though they meet standards turn out certified divers who demonstrable can't dive. The end effect on me is that I closed the shop and eventually quit teaching because of my unwillingness to continue to deal with the agencies who are totally clueless about what it takes to dive safely, teach safe diving and don't seem to care much one way or the other. the rely on a seemingly low death rate to justify their useless standards. The fact is that a person can don scuba with no training at all, sink down, walk the bottom for a while and climb out without getting killed. That is not proof that their training was "good" or "adequate".
Apparently we're ok with the fact that 100 divers per year die in DAN's reporting area and that things like buoyancy control problems are reported in over half the fatal accidents. Of course we can visit any number of busy dive sites and witness a dozen uncontrolled ascents (fron various causes) and a like number of buddy seperations in a weekend. Which ones result in injury or death is a matter of luck but most are survived without injury and so go unnoticed all together. Still, I spent too much time helping divers out of the water, directing traffic for ambulances and searching for missing divers. How many deaths are acceptable if it's your family or your students that we're talking about especially if it was completely avoidable?
So, does it effect the industry? Not much but some. I'm not the only instructor who has seen enough to stop believing and stop repeating the party line. Most of the good instructors that I know have removed themselves from thew mainstream dive industry and no longer teach for shops because of how they are forced to teach.
