Giving people scuba equipment and telling them no training is necessary.....I don’t see what could possibly go wrong......
while you’re likely hood of getting bent is pretty low.....there are still a myriad of other ways to hurt yourself..... ascension rates, clearing and equalizing, out of air emergencies, lung expansion.
someone is going to take this, go diving, run out of air, and because they weren’t trained they are going to hold their breath and make a dash for the surface and pop a lung.
and god forbid someone who doesn’t know any better pump this thing up next to the tailpipe of their running car...
