Hi Case, (snips) > Either I'm high while reading this thread (an impossibility, and I've > got the drug tests WEEKLY to prove it) Ummmm, why? No, forget it, it's entirely immaterial. > or you're the one mis-reading. Misreading what? I doubt that I misread anything, but see below. > I > did in fact get the impression that the doubles in question were > manifolded, Indeed, but the person I criticised alleged that they were NOT manifolded, which was the first part of my argument with him (and only him). Did you misread this in my post? :) and that the gas management rule was quite absurd. But the gas management rule is NOT absurd when you can't read an SPG in most of the situations that these people dive in. This was the second part of my argument. I wrote: > The reason is that they often (mostly?) dive in such crud that they wouldn't be > able to see their SPG's anyway. Therefore, decanting their bottles in this > fashion is, I would think, the only form of gas management available to them. > I would have thought that, in this type of situation, even taking an SPG is "absurd". > While you are correct that these guys have been doing some of this > diving much longer than most on this list, the logic does not follow > through. How many Oz Navy divers (or any Navy, SAR, or professional > teams with large budgets) have you seen 18,000 feet back in a cave > lately? I would suggest that this is entirely immaterial. The bodies we are here discussing do it professionally, as I carefully pointed out. They are not interested in caves, as in the WKPP, they are interested in pulling bodies out of the water in extremely turgid conditions, often in inaccessible places, often with strong water flow (streams, tides), sometimes in places where you and I could get extremely sick because of pollution. They are interested in searching for things which the courts would find valuable as evidence. They are interested in things I probably haven't even thought of and (mostly I would think but I don't know) they are paid to do these things. You and I are not paid, but you and I therefore have the choice to abort the dive. They are NOT interested in going into holes in the wall (as in the WKPP), not unless there's a job to do at 'tother end. > The fact is, most governmentally funded agencies are very slow to change > techniques and technologies.

Absolutely, I totally agree, just don't confuse civilian divers (like the WKPP and their 18,000 ft and their agenda which is just that) with official agencies with an entirely different agenda. That is entirely the point. > I personally HAVE tried mounting my doubles upside down. Plain simple > fact: after many hours of experimenting and re-configuring, IT JUST > DIDN'T WORK!!! I don't care that other, more professional groups do it > this way. For the diving that I do, upside down cylinders is WRONG! Well said and well tried. In my post which engendered the response from that other party I also said: > This is not, however, an excuse not to mount tanks "right way up" in today's more > enlightened times.

That person has not responded, possibly he has decided that what I said was correct, maybe not. Until any other development on that front, AFAIAC, that particular matter is closed.
