I really do not like the idea of diving a rebreather without a HUD to watch my PPO2. My Shearwater HUD gives me all sort of warm fuzzy feelings while diving my KISS.

I agree Kevin. A HUD, especially in a cave, is one of THE most indispensable pieces of equipment you can have on a Rebreather. Short of sticking your head physically in the mud, a HUD can be seen in all sorts of low/no vis situations.
