Scubapro regulators under Ice

[rhwestfall]

the S555 came paired with the MK-17. That was a plastic barreled second. Thanks to Beaver Divers, mine is now a metal barreled S600.....

The smaller size of the SXXX seconds aside, I actually like my MK-17/BA156 combination the best of my collections (though never marketed that way).

Then again, I am itching to put my Kraken into some really cold water.....:vintagediver:

I use the mares Abyss 22 Navy 1st and second stage. It is torture tested by the US Navy to incredible lang-cs what the United States Navy SEALs users so I figure it will go far beyond anything I will ever ask

I've had no issues with my Zeagle 50D and Z secondary here in the Great Lakes. Bottom temp on Aug 24 this summer was 39*f @102 feet in Lake Huron.

That's probably because if it isn't actually made by Apeks, it is pretty much a clone of a Apeks.

Great info. Does that mean that there may be a chance an Apeks service kit will fit the Zeagle Z and Zx regs?

I have dove 38°F waters with my G260/MK17. Performed impeccably.

Most of our cold/ice divers up here in Maine set up their gear, but won't turn the air on until the first stage is underwater and don't take a breath until the seconda stage is underwater. I taught a dry suit course a few weeks ago; dive 1-36 F fresh water with 37 F surface temp and dive 2-40F salt water with 24F surface temp. My student's Atomic froze up on dive 1 and I switched him to my Sherwood Blizzard back-up reg without any issues. He used an old USD Conshelf for our salt water dive and was fine. I dive a Zeagle Flathead 7 and didn't have any freeze-ups.


Around here, the older dry-bleed Blizzard is the go-to for divers who have to go out in near-ice conditions (Public safety, harvesters, etc.). They aren't the easiest breathers, but they're simple and reliable. I don't know of anyone diving the newer Blizzard, so I can't speak to their performance. After the Blizzard, Scubapro MK 17/G250 or 260, Apeks, then Zeagle.

my Poseidons, Apeks, and Hogs survived the Maine winters just fine The Blizzard bleed though is pretty spiffy though for preventing freezing. Used them a few times, but always put my second stages on them.

The dry-bleed system effectively seals the regulator. It is a much more elegant solution than packing a piston regulator with grease. From what I remember all Sherwoods have this feature from the lowly Brut to the Maximus. The Blizzard has an exhaust heatsink which I assume could be retrofitted into other Sherwood models.

What is wrong with Atomic's M1 regulator in very cold water?
