Subject: Jetstreams freezing (was Re[2]: Freezing Scubapro regs.)



Hi Clifford,

Do you have any experience with Poseidon Jetstreams (Odins) with their 
upstream servo 2nd stage freezing?

I have heard a couple of unsubstantiated tales of them freezing shut.

On the general subject of 1st stage freezing, is it not possible for the
ambient spring chamber to freeze solid, clamping the main spring, preventing
the 1st stage from shutting?
Is this not why we put environmental seals on and fill the chamber with
anti-freeze solution?
