If the outside air is below or near the freezing mark, before the dive, do not exhale into the regulator until both the first and second stages are submerged. The moisture in your exhaled breath can collect in the second stage and cause freezing before you even get in the water. This means when you test breathe your regulator, only inhale through it; do not exhale back into it. It is also advisable to even minimize breathing from the regulator at all until it is submerged.

Plan your dive with the assumption that gear will leak and regulators will freeflow.

THIS IS SO VERY TRUE!!! EVERY DIVER NORTH OF CHICAGO TAKE NOTE!!!!!!!

Hey Soggy:
Great write up. And I thought only my fellow PSD's knew about adibiatic effects on tanks. LOL!! Considering my last ice training dive was conducted at -45 degrees temp. and a wind speed of 20 kmh. I'd say that you guys in the NorthEast are doing tropical diving!! LMAO!! And if reg freeze up and free flowing are a concern there's nothing like an old double hose regulator, those work horses keep on ticking!! Just getting harder and harder to find parts these days.

Thanks for this, very useful information.
It's made me realize it's not a straight forward decision to dive or not to dive, it's not about how tough you are or how much diving you have done but how prepared you are and how aware you are of all the associated factors. I am certainly reconsidering all my future sub-zero diving.

Thanks for this forum

Would you like to try a heat exchanger on one of your dives (we call it Mark M)? Have a look here:

Let me know if you'd be interested and I'll give you more details. Given your understanding of the temperature drop in the procedures section of your blog, you should also inderstand the physics behind this device (and this one has very large heat exchange area).
