    I check the valves before and after submerging.......just because it makes me feel better about things. I know, compulsive...

    Good thinking scared silly. I have an SPG on the left cylinder and I have my dive computer's air integration on the right cylinder/ This could be a goer

    Good one divad, now I know which was to turn the isolation valve to make sure it is open, I will do this too

    This usually works for me, but I sometimes find 'righty' and 'lefty' can become confused at strange angles or when reaching around/over/through things.

    For example, with a standard single tank on my back, I can't think 'righty' or 'lefty'. Instead of I think of the direction it would 'roll off' if I was in a cave, and then I can easily know the direction to turn.

    Vindicator knob might be something to look into. Just a visual tool for an extra check, after you physically make sure the isolator is open.

    You can't can't see the Vindicator on back mounted doubles when you're under water. You simply Must be able work the valves underwater without being able to see them. It's non-negotiable. If you "need" Da Vindicator, you need to NOT be diving back mounted doubles. I'm always solo fwiw.

    Why?.... I'm going to check them, or turn them on, without being able to see them before I get in the water......is it something to do with "the redundancy of redundancy department?"

    Why not? How does it hurt?
    As nice as it is to say "no one touches my tanks or valves" if I'm on a boat full of poeeple, especially if they are not all tech dives, stuff happens. Nothing wrong with a visual check in addition to all the other things you do...but it surely ought to be secondary to an actual hands on check.
