Bailout

[Inspirationdiver]

Planning bailout for trimix rebreather dives is not a straightforward concept. There are some very different views on what is appropriate. Anybody want to share their opinions on what should be carried?
Assuming that you are going to carry 2 stage bottles, it is accepted that one should be a trimix bailout gas for at depth, and the other should be nitrox, deco gas, or oxygen.
The problem is that the ideal content of your second stage bottle is not universal to all diving depths. Adjusting the FO2 of your second stage bottle can greatly alter the amount of gas you consume out of each stage bottle.
