Snorkel

I second the advice given by other posters. No diving with compressed gas
is entirely safe and you need to get training to do such diving safely.

There are several other companies that sell units similar to Brownies. Do a
search for hookah.

Point taken--However many mining incidents from those times seldom go
reported.The length of hose that you trail in a hookah situation also
presents its own specific set of problems--in a comercial situation each
diver is on a seperate supply and also has backup air resource, which
he(she) can swop to instantly without thought.A multiple hookah system as
described is no more than a "t" piece from the supply--what happens if a reg
goes free flow/hose gets cut? I doubt if the compressor has enough
redundancy in supply to cope.

Commercial, yes. Those guys, no. Usually a small tank is placed between the
compressor and diver so they don't have to worry about overbreathing the
thing and have time to surface if the compressor stops - and they hear it.
