    Would you want that much air in the counterlungss? The meg CTL's are huge.

    I guess at least open up the OPV to the max than.

    Yours are at least 1/3rd bigger than mine. You might consider having yours sewn down (on the edges) they don't need to be that big.

    I leave my OPV basically wide open.

    Re: With dive OC buddies

    By the point in my brief where I'm talking about flicking switches on BOVs the O/C buddy already has wide eyes. If I start talking about diver lifts (not usually touched on before a rescue level course) I'm going to lose them or ruin their dive.

    I dive with my OPV fully closed. I know that, if a new diver attempts to lift me, I'm going to the surface fast. It's better than staying on the bottom. And it's usually pretty shallow if I'm with an OC buddy.

    I would never remove a DSV to try and put in a regulator (unless the DSV had already fallen out). If there is any respirations at all they will drown.
    Makes sense and the answer I was expecting.

    Who knows what their ppO2 is.
    Some units have buddy displays such as the liberty but not common.

    A dil flush on the bottom might in theory hel,p but I wouldn't plan on anyone knowing how to do it. But I wouldn't try to teach an OC diver how to do anything (new-to-them) other than switch my BOV.
    What about a CCR diver helping another CCR diver? There is a greater prevalence among CCR divers to self reliance which is understandable given the greater complexity. Still it does result in a "as long as I am conscious and in control I have a chance. Once I lose that it is all bets are off" type situation. In CCR courses are diver rescues of a non-responsive causality featured or not? I am guessing GUE's course would?

    I prefer the large CTL's, especially on ascents.\\Never open my OPV, unless doing an O2 flush.

    I had to do unconscious CCR diver rescues in my MOD1


    From about 12ft in the pool and again in open water in perhaps 50ft. Nothing like 30m but it was MOD1 and we only have one BO on and minimal wing gas.


    Tap them to see if they are conscious
    Dil flush
    Bring them up with as much control as you can venting from the loop and drysuit a bit as you go.


    I didn't find it to be all more difficult than on OC. Neither of us had BOVs in class but if they have one just turn that on instead of the dil flush.

    What did you do to vent to the loop?

    Also more thinking out loud here, what if the person has there OPV shut and uses a DSV? I am guessing the expanding gas will want to push the mouth piece out so a firm grip or gag strap could be very important with excess gas escaping past the lips.

    It just vents out the lips or nose. Most OPVs aren't at the top so being open doesn't help so much. Some units / CLs don't have an OPV at all either.


    I didn't find it all that different than an OC diver lift and I had only 2 or 3 hours on the unit when we did it in the pool, maybe 6 hrs when we did it in OW.
