| Re: 2 computers, or ? 1 computer, 1 bottom timer. I also carry a set of constant PO2 air tables - not that useful if I'm diving mix (no cert yet). However I don't get into very much deco, keep a very close eye on how much, and am pretty confident of doing a fair approximation to the profile my VR3 would have given if it fails, or if VR3 and Rebreather both fail. May need something more as I start going deeper/longer.
