Just read "Lessons From The Last Dive", an account of two deep wreck diving fatalities that occured in 1992 by two very experienced East Coast "wreckers", Winter 2000 issue of IMMERSED, page 27. Although trimix trained and experienced both father and son elected to dive 21%. Shit happened and they both died from decompression sickness. Apparently they became victims of the economics of high tech diving: not enough money to pay for the proper deep mix. I post this because there seems to be a growing belief that ALL divers should dive heliox or tri to any depth and avoid breathing nitrogen. 21% diving is expensive enough without the added cost of helium and the difficulty to get it. As it is, I pay twice as much for EANx fills. So where's this headed: a sport only for the wealthy?
