Recent double hose reg training?

[rx7diver]

@rx7diver : I just run an independent (pony), also with a spare QD for DS.

Yes, your approach seems solid--provided you follow the "rule" emphasized when I first began diving the Great Lakes (using a single tank with a single 1st stage): Don't inhale, inflate your BC, and inflate your drysuit simultaneously! And don't inhale and inflate your DSMB/liftbag simultaneously. Moreover, your approach allows the DH can to be located optimally, too.

(One distinct advantage of the two Poseidon's on a Y-valve is, they can be moved from the single cylinder directly to manifolded doubles or back-mounted independent doubles without having to change anything around whatsoever--except maybe add a second SPG in the case of independent doubles. Of course, hose lengths optimized for doubles won't be optimum for a single, but they'll still work well enough.)

I just get more regs...

Two older books that I have in my library are:

Barada, Bill, "Let's Go Diving, Illustrated Diving Manual," U.S. Divers Company, 1962 (fourth printing, 1965).

Cross, E.R., "Underwater Safety, Instruction Manual," printed by Healthways, 1954, 1955, 1956.

Both are excellent manuals. But, remember that the diving tables in all these manuals are pretty old, and that you should use the newest U.S. Navy diving tables for all your actual diving if you don't use a dive computer.

Wait! I thought you absolutely had to use the old tables, and the old rules, if you use classic gear. No?

No. There's been a lot of research in the last 50 years.

Vintage divers became vintage by accepting good ideas and eschewing bad ones.
