    The problem for me is I'd inhale that wee bottle in one breath first time I saw a shadow. Not being a diver, it takes me 20 minutes or 1/2 an hour to settle down just snorkelling. I mean I know they don't want us here, but I have seen some very big units with teeth over the years

    I've no doubt that used conscientiously it would be a useful thing, especially where room is an issue. Refresh the air regularly and try the unit regularly before you actually need it. If you do get one, please let us know how you find it.

    And remember the foot note that hand pumping this thing is a 45 minute job. Of course, with the right attachment, you can fill it from a tank. In which case that tank has that much less air, rather reducing the tank by whatever you think this thing's safety factor might be.

    I reckon I've heard of someone rigging up something witha plastic soda bottle. Not very high pressure obviously. Just a few breaths I guess. But that could extend your underwater time by a factor of several.

    Looks cool and if you used it for nothing more than checking your bottom (THE BOAT'S BOTTOM!) or diving on your anchor (down and back up) it would probably be okay. Last year when we were crewing in the O.W.R. the owner had a hookah which worked pretty well when we wanted to clean the bottom. Wife and I got PADI certified while we were in Vanuatu and dove there and in Indonesia. Fun, but I'd rather be sailing!
    The only difference between [where I work] and the TITANIC is... The TITANIC had a band.

    I think this gismo is simply useless.
    Hand pumping will hardly reach 7 bars (100 psi).
    This is ridiculus.
    According to the visible size of this small tank, only enough to breathe 3 or 4 times at ground pressure...
    And I wont try to inflate it at 200 bars... (3000 psi).
    This thing seems intended to internet gogos
