Interesting. >> Hi Tom, What I have been discussing is the invalidity of almost all of the reasons given for not using wrist computers for extended decompression dives. The reasons simply do not hold up under careful scrutiny. And it really bothers me when a bunch of people all say the same thing, and when I ask them why, they parrot the same refrain without having ever thought critically as to whether or not what they're saving was correct. DIR appears to be an excellent system. But I believe that any technical diver that accepts ANYTHING without questioning it and convincing him or herself that it is correct, is an accident waiting to happen. I want all of my students to question and understand the background for anything I teach. And then convince themselves that it is correct. For if they can't do that, then we need to discuss it further and just possibly I, as well as they, may learn something new from the interchange. As I have stated, I believe that almost all of the arguments given to justify not using wrist computers for decompression diving, are bogus. However there is one point with which I do agree and which causes me to not depend on them at this time. That is simply that the algorithms presently implemented in the computers with which I am familiar, take too damn long to deco me out of the water. That and the fact that I do not yet have a computer capable of handling helium. So the answer to your question of "What is the point here Scott?" is that I am trying to politely request folks to critically look at their reasons for selecting diving equipment and techniques in general and dive computers in particular. And if after careful consideration, those reasons make sense then great. But IMHO it is just plain WRONG to accept or reject anything dealing with life support situations just because it was announced by George Irvine, J. J., Michael J. Black, Tom Mount, Bret Gilliam, or anyone else. But then, of course, that's only my opinion. Thanks a lot for the note, I appreciate your caring enough to take the time to write. Take care now and safe diving, Scott -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. Send subscribe/unsubscribe requests to `techdiver-request@aquanaut.com'.
