I am seeking advice from anyone who has done any ice diving with their photographic equipment. This weekend I am signed up for an ice diving ceritfication course and would like to take some pictures. Specifically I have a canon 20d with an ikelite housing, dual 125s etc. Is there anything I need to be aware of with this housing to prepare it for below freezing air temps and mid 30's water temp. My concerns center around the seals and how they will respond to these kinds of temps and whether or not they are more likely to fail.
The equipment will be sealed at home prior to going to the dive site, with special attention taken to insure as little humidity as possible is present within the housing prior to closing it up. I will not open the housing again until it is safely at home and it is once again at room temperature. (common sense in my neck of the woods).
Thanks for your time!
Sincerely,
