Cave Diver ...remember one thing the three other divers were certified ...which in my book makes them culpible for their own actions ...apparently they had the ability, poise and skill to preform a shared air ascent and then recover with ample air for a safety stop ...albeit reckless by todays standards but hardly not out of the pale of skilled certified divers. No worse than having a little too much christmas cheer and driving home on a freeway @ 75 mph in a 2 ton vehicle...which I suspect most of us are guilty of at one time or another -eh?
I fully agree that they were certified and thus responsible for their own actions. But just because they were certified does not necessarily mean they were
aware of all the risks associated with this dive, although I'm sure they signed the standard "diving is dangerous, you could be killed yada yada yada" waiver.
I have asked questions to ascertain the precautions and skill levels of the divers who went on this excursion. All of which have gone unanswered, even though the OP has returned to this thread several times.
I'm still curious what his "screening" process is. Did he do several shallow dives first to ascertain their skill level and ability? Certainly they didn't flash a c-card to be allowed on this dive, because that depth (even 150') would require more than just an advanced certification. So, if they were only "advanced divers" why would a dive op assume liability of taking them on a dive that is outside his agency standards?
I'd also like to know why since by his own admission this is a "dangerous" dive, the clients were not provided redundant gear. I see posts on here all the time by divers with much less experience who at least carry a pony bottle.
While they may have the
skill to perform air sharing, do they have the experience or skill to do it while narked at 150'? And what did the guide do to ensure they did? Checkout dives? Air sharing drills? Emergency ascents?
The clients carry their own share of responsibility for their actions, but I question how well they understood the potential dangers from their "guide." Complacency kills. If divers are complacent with who they put their trust in, they might get hurt. If those entrusted with their safety become complacent, people may get hurt. If this thread does nothing but bring awareness to "what if" then it has served a purpose.
In response to your "holiday cheer." I can honestly say that I never have. I lost a close family member to the actions of another careless individual at a young age. While he was responsible for his own actions, he couldn't control what the driver in the other lane was doing and as a result, he paid with his life. So I advocate that even less than I advocate diving recklessly.
