    Doing a review of of my rescue stuff and working on my dive master there are times when you have to remove your reg to do some rescue breaths while in water. Removing your mask in the water would cause it do hang and given the size it would create drag. Would it be hard to have a loose or safety strap that could connect from the back of the full face mask to the safety strap on the BCD that goes around the tank valve? that way if you had to remove your mask in an emergency it would hold it out of the way and still close to you preventing entaglement and reducing drag.

    Just a though..

    What difference do you forsee an additional strap / tag make though compared to it being connected to you still by the low pressure hose / reg that feeds the full face mask? struggling to visualise the difference in water of a full face mask hanging by the hose compared to hanging by a strap?

    I will occasionally switch from my full-face mask to a conventional one, on a dive. I simply carry a decent-sized carabiner on my BC; and can easily attach it to the mask's "spider" harness, so that it can lay against my chest.

    Some FFMs also feature a neck harness option . . .

    For rescue situations it would pull the full face mask out of chest area to allow greater ease for rescue breaths, also it would prevent damage to the mask when exiting the water.

    Like i said, just a thought,

    I don't even know what "allow greater ease for rescue breaths," means. We did rescue drills with that set-up years ago . . .

    I'm not sure if this is something you are considering for actual rescues, or specifically four your divemaster training / activities.

    For actual rescue scenarios I don't think it would add much:
    - drag is lower when the FFM is connected with only a hose as opposed to connected with a hose and a strap
    - FFM drag really isn't that interesting overall, remove tank and bcd altogether and have the victim float naturally, combined with added buoyancy from exposure suit (if used) in order to remove drag and get the victim out of the water asap
    - damaging kit when getting out of the water is not a consideration. If it is in the way, it goes. If it sinks, it sinks. If the situation allows for it, retrieve the kit (especially tank, bcd, regs) for any future accident investigation, but if it gets in the way of treating the victim asap, leave it. This includes expensive stuff
    - If you design and produce something special, rescue training has to adept to it as well. Just compare a rescue with a jacket BCD with a rescue involving bp + harness. Different technology requires different rescue technique. Luckily, the universal technique of using a proper line cutter works really well...

    If it is for your DM course (or during rescue courses you might assist with in the future) you might want to consider switching to a normal mask, as it will take more of a beating during activities like that. Students who get excited and pull to hard on straps, drop stuff etc. Safe the FFM for when you are actually diving. Also check with your instructor on his / her philosophy about using kit that is as comparable to your students as possible. Cases can be made for diversity (broader experience) but also for standardization (familiarity), so keep that in mind when selecting kit you use during dives like that. It can be really good fun to play the victim, but unfortunately equipment will be abused..
