Just another take on "what's a deep dive":
I've been working my way through the UHMS 1997 workshop report on "Near Drowning" that was recommended by Jon Kranhouse in post #69 of this thread:
http://www.scubaboard.com/forums/accidents-incidents/331412-diver-dies-islamorada-2.html Interesting reading, a little slow because I'm not medically trained so I'm looking up terms in Wikipedia almost every paragraph. But back on point for this thread:
From page 28, discussing "Depth of Incident" among contributing factors [Bolding is mine]:
... This demonstrates that it is not so much the environment that is the problem, but the diver's experience of that environment. The danger of "diving deeper" without extra prudence and supervision is apparent. Any dive deeper than that previously experienced should be classified and treated as a "deep dive", irrespective of the actual depth.
I think the Bonaire guidebook is referring to the PADI threshhold of 60 feet for OW certs that others mentioned above, but considering the distribution of experience of resort divers, the Hilma Hooker is likeliest the deepest dive attempted for many, if not most, that dive it. I know it's within a few feet of mine.
My point in posting here is that the advice of this quote from the near-drowning workshop emphasizes that any scorn expressed at calling that "deep" in a guidebook leads, at least somewhat, to the sort of peer pressure that gets divers in trouble. Not helpful.
So all you guys that do 200 ft on air, great. Enjoy it. You aren't the guidebook's primary target audience, and there's nothing wrong with that.
