    Re: Inline shut off valves- thoughts please?

    This is a very interesting discussion. Actually, exactly what I was hoping to hear. I still don't have a yes or no on my thoughts on shut of valves but my gut is (as a v DIR compliant diver 'open circuit') keep it simple and not add stuff that can lead to additional failure points and added complexity to your equipment.. but I do wonder if that at some point not having a shut off valve on bailout could bite me in the ass.

    Good point, divingabe.

    If you're using shutoffs maybe part of your regular drills should include not only popping the valve as you switch to that reg, but also popping the valve when you donate.

    If you are a DIR diver, then why even bring this subject up? Its counter DIR principles and you wont change anyways.

    A bit of a disclaimer: I dive a bunch of twenty year old Poseidon regs that have a switch to turn down the sensitivity of the second stage.

    While they work just fine, they have there own issues. Puting them aside, I am able to scooter in relative comfort knowing that they are unlikely to dribble.

    Last night on a OC dive one of my second stages started to crap out. It took me a few minuets to work out where the racket was coming from, but then I was able to throw the switch and still have a rev I could breathe from.

    A feature I have not see. On other regs, but one that has served me well.

    Cool Re: Inline shut off valves- thoughts please?

    NO shutoffs on bailouts. Valves open ready for a full breath FROM BEGINNING TO END OF DIVE WITHOUT GAS LOSS. I have been on both sides of the regs in an emergency.you should have your gear together, no dribbles from leaking seats overdue or bad servicing or misadjustments,if you scooter have it adjusted accordingly. I also use posiedons which have their own opv i try to keep failure points down and keep things clean and simple without adding 1 more thing to do under stress. If you are staging in a cave its acceptable to charge a reg then turn the valve off again there should be no gas leaks,but that is not a bailout tank it will be for planned usage.

    Having had to clean salt infested first stages after forgetting to turn the bailout on before, and after having a dive where bubble check was fine but I must have knocked the 2nd stage in a wreck, got back to the surface and noticed my bailout tin was empty, I will respectfully disagree. For me, anyway.

    Totally disagree with you. You don't know me and you have simply made an assumption. I, on the other hand know myself reasonably well and can say whilst on OC I am pretty DIR compliant I am also not a fanatic. I have trained with GUE and dive with GUE divers but mostly IANTD and have adopted pros from various agency and diving philosophies.
