I do all my under water work (changing props and zinks, etc) using a
"Hooki" rig. It's basically a SCUBA setup with a long hose between the
first and second stage regulators. I got the setup from Brownies Third
Lung.
That's the Cadillac version, but I happen to know one fellow who used to dive
with a Red Green apparatus similar to the one described below.
Buy a snorkel with an open top, and one-way valve (check valve) at the
mouthpiece for clearing water. You must have a one-way valve. Your breath
exhausts here, and excess air pressure is also relieved here. Fasten a
garden hose to the top of the snorkel. (Duct tape?) Connect the other end
of the hose to the air discharge of a shop vac. (More duct tape?) Don't
hold your breath. Apparently good to 4 or 5 feet, depending on the vacuum
cleaner.
A refinement is to attach a short length of hose to the exhaust from the
one-way valve, so the bubbles exhausting around your face don't drive you
nuts. Relocating the one-way valve to a tee at the top of the snorkel does
the same thing better.
I can't recommend the use of this rig underwater, but that fellow I happen to
know had fun with it.
