Mr.X:I do think written, or multimedia-based learning tools would be very, very useful to fledgling divers who tackle NE diving. Some of the divers that I see on shallow day boats in the NE aren't ready for the currents, limited visibility, variety of surface conditions, protocols and overall harshness that the Atlantic sometimes reaps on divers who are expecting something a tad more pleasureable.
Without commenting on this accident, since I dont know the experience or training of the victim, I wholeheartedly agree with this. When they say you are certified for diving in "similar or better conditions to those in which you were trained," they're serious. It goes both ways - cold, dark, rough North Atlantic is several quantum steps away from clear, warm Caribbean reef, but at the same time I've watched ripping South Florida Gulf Stream current - in clear, warm water - play hell with Northeast divers too.
We need to emphasize to divers that skills and protocols like lost buddy, safe ascent, and weight belt removal must be maintained with regular diving and practice, and that experience with conditions other than those in which they trained built slowly, step by step.
As for this accident, I feel very sorry for the victim and his family. I have been trying to get my own brother into diving and I would be devestated were something like this to happen to him.
