My ICD management is simple, Never use Air as a deco gas[1]. Its just a awful deco gas. Joking aside, I use the pp graph's in subsurface for inert gas pp management. Just make sure they don't rise above what you are saturated on. A comment on the IANTD rule of thumb, is that another one I've seen is to never raise the inert gas pressure by more than 0.5 on a gas change. From what I've read V-planner uses this rule. Ex. on a 100m dive, on 10/70 , I wouldn't have any problem using 21/35 as the first deco gas, but I would probably throw in some extra he, making it a 21/45 or something. //Anton 1. Unless I'm doing a air dive, and mange to build up some deco time, and don't have anything better around... -- Anton Lundin +46702-161604 _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
