Hi Christopher,

Last week we spent quite a bit of time working out a surface decompression
routine for Abyss to be used by commercial divers.
The gist of it is that a diver can ascend from 40ft, regardless of deco
obligation, to the surface.
We allow him 5 minutes (MAX, 3 min is much better) to get out of his gear,
and get into a surface recompression chamber.
We then blow him back down to his last depth + a factor, and then decompress
him back to the surface as though he were making an altitude dive (suface
pressure < 14.7psi).
end quote.

Is this a surDO2 or air?  If it is air (which is what it sounds like) then
I expect that you will meet a *strong* resistance to this system. Surface
air has been just about shitcanned by the whole industry.  If it is O2 then;
*HUH??*  It sounds really wierd, where did you get the idea from?
Cheers Jason :)
PS will the sur D be in the Abyss that the punters buy?
