    Scooter gas management

    Yeah, we had talked about it prior to my taking Edd's class. I got from Edd that there isn't a hardened fast rule and we went over calcualtions for gas needed for complete failures from max...

    Lost Shearwater Perdix at Jug or Manatee

    Didn't realize it was missing until I got back home to TX and unpacked. It's on an arm slate and I have the SN.

    Are cannister lights still necessary?

    I got a chance to try a Halcyon Focus LED light in our local turbid water last year. I wasn't impressed, and wished I had been able to use even my 24W HID instead. The HID can be focused so that the...

    Scooter gas management

    Halfs is the way to go.

    Imagine you had something seriously go sideways on your dive. You're scootering out on a stage bottle and when you hit the next stage (the one you dropped on the way in,...

    Scooter gas management

    so Edd's class has limited discussion on gas management because no one rule solves all, you need to calculate on every dive what that gas management plan is going to be based on your factors, and...

    Scooter gas management

    As for "breathing the stage" I have heard several different definitions. I have heard breathe half in and other half out (not going below 500psi), 1/3s on stage, and half plus 200. I would think that...

    Scooter gas management

    Generally speaking breath the stages and keep backgas in reserve. If you want to swim somewhere it's cool IMO to use backgas so long as you reserve enough to get out of your scooter breaks. Having a...

    Solo Sidemount Gas Management

    This makes sense, I've read about at least two accidents where someone drowned within sight of the stages they were swimming to, and at least one where *just one* stage or safety put where it should...

    Scooter gas management

    The "off the trigger" part is the bigger issue. IF you can use stages while off the trigger, then that is probably best. If your off the trigger passage is small, you need to save enough gas for...

    OOG during Deco

    if you unclip and donate the long hose you're going to have a CF of tangled hoses to deal with. donate what you're breathing and move that diver onto a long hose if you need to (for some reason he's...

    Donate what your breathing immediately, you know it works and it's quickest to deploy. Sort it out after

    Scooter gas management

    I've been hesitant to ask this since passing Edd's scooter class, but FW's comment in another thread made me decide to go ahead. As I've said, I passed the class and I know many people are afraid to...
