| Re: Diving deaths in The Red Sea?
Having been pretty whacked out at 150' on air and having had one bad "dark narc" experience around the 130' range (which I likely precipitated with a "bomb the bottom" descent into relatively bad conditions - low vis, bad current, etc) I've learned from the error of my ways.
On OC its always a trade-off in the "intermediate" ranges where air "can" be used, because the cost is quite high (outrageously so in some parts of the world.) But on a CCR, this argument melts away - there's simply no reason not to use Helium on anything below 100' - there sure isn't a cost issue!
I think its entirely reasonable to cite narcosis as a contributing factor at minimum.
