Regulator Use in Cold Water

[Dustin_360]

Good info...

Also, has anyone here used the Atomics in cold water? Just wondering if anyone has any first hand experience with them in the cold water. I hear the sealed atomics are expensive to service because of the Christolube or whatever it is called.

I second the use of the Sherwood Blizzard. I have a Sherwood Magnum 2 which uses the same first stage as the Blizzard. I have dove it since 1988 many times in the cold quarries in Ohio (37 deg) with zero problems.
This is actually a positive pressure reg instead of an eviromentally sealed one.

I disagree with this statement as well, I have seen no evidence that breathing on the surface leads to free flow,

I agree with web monkey "The problem is that the amount of cooling depends on how much air you're using"

I usually reccomend my students dial down the amount of air if they have the option on their regs, and this has seemed to help reduce the number of cold water freeflows we have

When you take your ice diving cert you will be taught not to prebreath your reg. It's in the course and for good reason. But of course in ice diving your exposed to sub zero surface temps and water temps around 35F to 37F. That's truely cold stuff which will cause many expensive regs to fail, especially if it's deep water.
If you don't believe me, join me for the Pearl Harbor Day dive in Fish Creek Wisconsin. Last year we had 15F surface temps and 33F water. We'll see who's right.

I can't believe no one has mentioned Apeks. I had my Apeks DS4/XTX50 last weekend at 106FFW with 37F bottom temps, worked flawless.

I started another thread asking this same question and haven really got a good answer yet.
