DECO the Dark site in recreational Diving

Without knowing the percent of divers using the 88, the statement may or may not be relevant.

There could be 10 times more with x than with y. But if 100 times more use x than y, then x is the safer.

Very true.

this is an informative thread that (hopefully) highlights one of the very clear gray lines in scuba diving: there is no such thing as "simple" deco diving.

It is indeed an informative thread, and it's just the latest of many that have raised the issue of "light deco diving." As someone very succinctly explained it either earlier in this thread or in a previous thread, at some point in what is already a gray area the risk increases non-linearly. In this area, just a little more bottom time leads to a LOT more risk.

A lot of novice divers seem to be in love with depth, and frustrated by the fact that deep dives are necessarily short, if you want to avoid deco. Of course, deep dives for novice divers are often EXTREMELY short, if they are paying attention to their gas supply, because the high consumption of new divers is even more frightening at depth.

In addition, divers whose primarily attraction to diving is wrecks, often find that the well-preserved wrecks sit deep enough to make bottom time brief, which is particularly annoying if you have paid a hefty charter fee to go out and see them.

I'm lucky. Depth has never held any appeal for me in and of itself, and I like critters, which are more abundant in shallow water

critters and bottom time for me.

why are people more focussed on depth and not on bottom time. anything less than 60 minutes is a non starter for me.

I'm not sure "a little bit deco" is analogous to "a little bit pregnant," since every dive involves decompression in one manner or another, but I did like your "clear gray line."

Is there an emoticon for "oxymoron"?

I feel the same way, but getting someone to sit around while I deco for 4+ hours can be tricky

I think this is a point that most non-deco-trained divers don't appreciate, especially the "light deco" recreational diver. After five years of crewing on a dive boat I can't tell you how many times I've heard some diver complain that his computer is effed up saying something along the lines of "My computer was showing me 4min of deco when I went after that lobster/scallop/porthole/fish... when I looked down five minutes later it was giving me 21 minutes! Piece of crap..."

As long as you do it while everyone else is doing their SI, eating lunch, and doing a SECOND dive... no problem.

:d

I love when the wind is picking up as diver's are going in for their second dive and some RB diver tells me his runtime will be 180min. "Um, yeah. No. Unless you think that's enough time for you to swim back to shore and meet us at the dock."
