    Dual Shrimp BOV anyone?

    The wetmule guys have always impressed me with their ingenuity. I don't think this rig is the kind of thing anyone dives in the ocean though

    Regarding the use of a BOB:

    I have a deep mix regulator necklaced, turned on, and ready to go. There is no need to fumble with the DSV, merely open mouth, push it up with regulator as I put it in my mouth. My loop hoses have enough weight to stay right in front of me and the water ingress is minimal before finally shutting it. This gives me a moment to sort out BOB before moving to it. Please keep in mind this is only when having to bailout in anger, most bailouts can be done in a slower calmer manner, but it still needs to be practiced so it can be done when needed.

    Since I have been forced to bailout due to a CO2 hit before the days of BOB, I know exactly how difficult it can be to get a regulator in my mouth without inhaling water. Ever since that incident, I have always been totally aware of my breathing rate and the temperature of the loop. I hope to never be complacent enough to let that happen again.

    , I have always been totally aware of my breathing rate and the temperature of the loop.

    Might be missing something obvious here, but how does loop temperature warn of an impending co2 incident?
    Thanks.

    As far as the sorb is doing it's work the gás should have a warm feel. If it starts to cool down MAY mean the scrubber is losing it's function
    The CO2 absortion produces heat. It's how the temp stick on AP's show you scrubber usage

    I have found that if I am overexerting myself and thus causing my breathing rate to increase, that the temperature of the loop gas increases too.

    sort of. The AP units measure where the heat is to see where the reaction front is to gauge scrubber usage. They don't really care about the absolute temperature of the reaction front because it is based on ambient temperature and CO2 production from the body. My experience echo's @Dsix36 's where if I'm kicking hard in high flow caves the loop temp can get unbearably hot and I actually have to bail out for a few minutes to let it cool off because I start to overheat.

    Yup! I've got the point you guys are saying!
    It happened to me already, and forget to take it in account on my answer!

    Anyone seen the spec for the dual integrated BOV on this unit??
