What's better than canned air?

The dive shops also sell some smaller and more convenient size tanks
for portability. A 30 cubic foot tank is really easy to handle. They charge
the same to fill a 30 as an 80 though. There are even smaller tanks too.
Some day I plan to make a fill adapter to fill my 30 myself from my 80's.
I'll have to be careful with that though. Fill very slowly to avoid heating
which is one of the reasons they set the tanks in water when they fill
them. Perhaps if the fill rig had a couple of small orifices by each tank,
that would restrict the fill rate for safety. One of the dive supply catalogs
used to list a tank transfer rig, but I could never actually find it. High
pressure
gasses can be very dangerous, so they may have stopped selling them.
