Tom, Glad to see your paying attention to us little guys. The instructor I was quoting will have to remain nameless, because he has a nasty habit of beefing a good friend for taking him to task for sticking his nose where it doesn't belong. Never a word to me or to my face, just behind the back bullshit. Nuff said. It has been my experience that the things I said are indeed true. I was told these thing were *required* not *may* be required. I am quite sure these statements were made simply to increase income, and to some extent, we can all understand that. But, what I have been told, and what you say are two different things. The reasons for this disparity may have several basis', I maintain its basically to make money. The triox issue, I stand on. Triox should be taught and used during very basic dive training, especially in the recreational arena for some very good reasons, reduced narcosis being the primary issue. IMHO, it should be taught and used during the very early stages of nitrox diving. As I am sure you know, mixes in the range of 25/35 and 32/35 can be dove just like normal air or nitrox, without incurring extended decompression obligations. Indeed, when diving a single tank, it would be darn difficult to get into a decompression situation with the available gas supply. I am not saying it cant be done, I am saying that most recreational divers have rmv's that wouldn't allow a decompression dive to occur on the available gas supply. At this point, no one, including IANTD is addressing the triox issue, except to say that it is useful for diving to 200 fsw. Some of us "guerilla" divers have embraced and are diving the gas with predictably excellent results. No shingle, no class, just a little common sense and working knowledge of diving. before ever even buying a bottle of He, we ran the stuff through every dive software available, and we get profiles that closely parallel air. The only thing left to do is blend it up, and go dive it. I would *almost* lay money on the fact that PADI will be adopting the use of triox very soon, and will be offering courses and shingle in its use, recreationally.
