Mares PI?

I've had my MR22 Abyss down to 38 deg in fresh water several times. It is not sealed, and has had no freeflows.

Here the ocean is 38-45 most of the winter & spring. I have not seen anyone using a sealed first (Apex excluded).

What is your defintion of COLD


Anywhere from 50f down to 40f (so far) but we are going to be doing ice recovery of vehicles this winter and the ambient temp hovers around zero f. I don't know what the water temp will be, but i'm sure it's going to be c-c-c-cold.

Not a huge deal. The design of diaphragm regs generally resists freeflowing and the metal second stage will make a huge difference. As longas you (I mean your first stage) is not in and out of the water on a windy day where there is a wind chill you should be ok. But for the ice I would be considering it. Depending onhow often you do it of course.
