Rich: I don't mind your 5 kb responses. I have learned a great deal from them, and I thought your last one answering the "Why deep air before mix?" was a good response, however. I'm a little confused. You said the following regarding the mixed gas thread. >And I don't agree with the statement "you cant >be a good deep mixed gas diver until your a good deep air diver". >However,I *DO* believe that a diver should have a LOT of experience >operating under conditions with narrow margins for error before s/he >even considers a trimix dive to 250 feet. I think that a lot of air diving >in the 150-200 foot range is at least ONE WAY to acquire this sort >of experience" They seem to conflict. That is, in order to be a good, or qualified deep trimix diver, you need experience with a narror margin. (Deep exeperience) and yet you say you don't agree about the deep air statement. "being a good deep air diver to be a good trimix diver." I read Bill's comment about being a good drunk driver to be a good sober driver. I don't think the analogy fits. If your diving deep, (130+?) you need to understand the logistics you and John Crea mentioned about deco, gas management, and the narrow margin associated with deepth. Plus the effects of narcosis on air or mix. Drunk driving is not a result of driving -- it's a choice. Narcosis is a result of diving deep (even with mix, your still must consider the potential effects) As one who is slowly working on deep air experience, what else can be done to help prepare for future gas training?
