Modern Doublehose Regulators???

[rstofer]

There is a lot of discussion re: cold water diving for modern regs and there are environmental kits and such to prevent freeze-up.

What is the status for the Phoenix DA AquaMaster in terms of cold water diving? I realize 'cold' is relative and I'm not talking about ice diving. I'm think in terms of Monterey; high 40's to mid 50's. As a complete guess, I would think that freeze-up shouldn't be an issue with the Phoenix but I don't know that.

One of the major advantages of most double hose is that both the first and second stages are environmentally sealed.

The Royal Aqua Master was the regulator f choice in Antarctica up around 1992, almost ten years after they stop producing them.

The design of most double hose regulators make it one of the best ice diving regulators, due to its resistance to freezing and the advantage that air expansion occurs behind you and there it has a chance to warp up a bit before you actually inhale it.

If you push all the limits and with some malfunctions it is possible to get a freeze flow in a double hose (it happened once to me), but it takes multiple malfunctions for that to happen.


Notice that many single hose have environmentally sealed first stages, but there is no practical way of environmentally sealing the second stage. Moisture from the exhaled air can always reach some of the moving parts in a single hose second stage.

As long as the air source is dry A PRAM will not freeze. Set the IP to 135 psi or lower for extreme conditions.

I am aware that the Phoenix Ram has been the answer to most doublehose divers dreams......however, I understand that using it with a DIN adapter is difficult to do for the length of the Phoenix nozzle........

Is there any interest, especially in England and Europe, for a diver useable multi LP/HP ported yoke/DIN RAM?

Here I am last Sunday with my PRAM. Air temp 15, water temp 32. Bottom time was 30 minutes. When I surfaced my head broke through a quarter inch of ice. All the wet gear froze instantly when we came out. Even the water on the face plate of my mask. I'd ice dive that reg anytime.

SwimJim don't need no stink'n wetsuit, everybody was shivering, not SwimJim, nope, he was getting warm and had to strip down to his shorts!

This is gonna sound really retarded to anyone who has not done it...but I miss dives like that. The other day they were whining about the extreme cold here - it got all the way down to 22 degrees.

Hey.....watch it Mr.

We got snow down here in Houston yesterday....had a few cars go ice diving.

Snowed over here in Louisiana also. White stuff everywhere! Tim
