Ultimate cold water reg?

[MasterGoa]

Ok, so I went back to Tobermory again this year with my RS-240 and experienced
the limits of this reg which is rated at 5C. So I cannot complain if it is problematic
at 1C at deep (150ft).

This would be my limit as it is the bottom part of the Forest City wreck.

So, having said this, which would you guys feel is the best performing
1st and 2nd combo at 1C and 140+ FFW?

Thanks in advance for you suggestions.

We use Aqualung Titan LX Supremes (ACD and Non-ACD), Legend LX Supremes, Apeks XTX50, 100, 200 at Toby without any problems.

heard good things about the Aqualung Glacia, though never used it personally.

The Old Blizzard works well in cold water too.

Atomics with the Enviro kits should work well too.

Love my Aqualung Legend and Glacia.

The Scubapro Mk 17 is fully sealed and when combined with a metal air barrelled reg like the G250V it is virtually bullet proof in cold water. Sp tested it at 165' with high flow rates in 35 degree water for 200 minutes and it was the only reg tested among several brands that survived the whole test without a freeflow.

Any fully sealed first stage design (Aqualung Legend Supreme, Apeks XTX200, etc) should do well in cold water.

That said, a double hose reg is the most bullet proof way to go in cold water as both the first and second stages are fully sealed. The first stage senses ambient pressure from the interior side of the second stage diaphragm. And that diaphragm and the non return valve in the mouthpiece also ensure the second stage mechanism is fully sealed from any contact with the water. Also, the large metal can itself offers an incredible amount of surface area to offset adibatic cooling in the first and second stage. Cold water reliability took a giant leap backward with the advant of the two stage, single hose regulator.

Does anyone even certify a reg down to 33F? I've had more than a few people that do ice diving and other extreme cold water diving rave about their Poseidon (I think the Cyklon). But, I have no direct knowledge of these regs.

any enviromentaly sealed first stage and a metal body second should do the trick for you. after service, as long as it is tuned properly will work like a charm.

mares also has a modular body named the NTT which has better performace then a plastic body but not as good as a metal. dont know what the cost on one is but it might be worth looking at.

also +1 to da aquamasters post

Are the Zeagle flathead 6 or even 7 any good in cold water?

sure are. i have used a FH6 in cold water, and i now have 2 FH7 on my double setup. have used them icediving and on hour long dives in 34-38 degree water with no issues
