Marcelo, The only use of neon I know of is as a deep gas to avoid helium problems. The surface supplied guys use it quite often and there is a legend of one OC dive made with NeOx off the Outer Banks somewhere. It hardly seems practical as an OC gas due to the tremendous volumes required for the depths where neon will do any good. Argon in a deco mix sounds good at first, but once you run the numbers, you'll see that it only has advantages for very long stops at 30-60 feet or so. Such dives normally use a chamber for deco since any time the 30 foot stop is very long, the shallower stops are even longer. We're pretty much into a saturation dive at that point. ArgOx has been used for medical research and I imagine that there may be therapeutic uses. Argon is much more narcotic than nitrogen, so breathing it under pressure can be counted on for problems in that regard.

Like Trimix as bottom gas, nitrox during the deepest deco stops and argox (or neox) in the two swallow deco stops. best wishes Moorea --------------------------------------------------------------- NetZero Platinum Only $9.95 per month!
