vicky once bubbled...
You can't really use it for subsequent dives, and you don't see any N2 tissue-lading graphs neither. I'm not sure it is wise to go deco using RGBM/Abyss.
It seems to work okay with a heliox load in the Inspiration, but I now have the latest and greatest from Dr. Bruce to compare it to. I'll let you know what I find! Thank you, though, for the cautionary comment!
