If you can't see your gauges then why does it matter?
Go to your bail out tables (you do have a bail out table, don't you?
) and modify based on what you think happened.
I never imagined this scecario occurring to me, because even though I have done some cave training on oc, I exclusively dive in high visibility beautiful South Florida waters and always at lease two computers that are capable of being switched to oc mode at anytime. I always run a bailout plan online to ensure that I have enough gas for a reasonable worst case scenario, but I do not carry it with me, because I never assumed I would not have enough visibility to switch my handsets to oc mode or see my PO2. However, in the future, and especially after reading this thread, I will carry bailout tables if I intend on diving anywhere involving serious penetration and the potential for zero viz conditions, just incase this situation rears it's ugly face. But then again, I dive an eccr, so a little extra sh_t would have to hit the fan for this scenario to occur and really screw me!
Good discussion - Thanks for the heads up!
