Comment on Making a 3d-printed Underwater Dive Helmet With A Floating Air Supply

  Oh I know, and I’m not worried about the guy trying this in his pool

  I’m worried about the idiot who thinks this too will work for a 30 meter dive, because there is always THAT guy who knows it all

    I can see someone strapping the helmet to their head, then get a leak while 1m deep. They notice when it fills up. Panic and try to get it off, can’t. Surface, it’s still full of water because the leak is at the air entry hole and they designed it to fit snugly around the neck and it won’t drain without tipping upside down. Drowns while struggling to undo the straps holding it on

      I’m assuming you didn’t watch the video, but this particular helmet design has a completely open bottom, and it needs weights attached to it to keep it from floating (he attached just enough weight to keep it neutrally buoyant). If it sprung a leak, you would easily be able to remove the helmet either by lifting it up off you, or tilting forward or to the side and sliding it off. it is not strapped to the person at all.

        Iron lung diving snorkel setup. Allows you to overcome the pressure and use a 15m long snorkel!

        And you accidentally set it to the wrong depth and blow up your lungs.
