The liquid inside the head of the 360 is not anti freeze and will freeze if it gets too cold and kill the whole unit. I was told that right from the head of R&D for Humminbird. I worked for a company that was owned by humminbird a few years ago and we brought that question up and that was the response. Basically were told it would be a good way to destroy the 360 unit.
360 for ice fishing

Rigged up a 360 bow mount unit for ice fishing; similar to an article in In Fisherman a year or so ago. Tried it this past weekend and couldn't get it to work. It seemed like the control head would not recognize that the 360 transducer was attached, because it kept telling me it could not detect the 360, and asked if I wanted to switch to F37E or something like that. Out on the ice I told it "no." In the living room now I tried it again and it gave me the same message. When I told it to connect to the F37E it read the bow mount transducer. Apparently the control head only identifies the stern mount, retractable transducer, as the 360, and calls the bow mount unit by another name. Its a shame, because I was on Green Bay and the fishing was very slow. Would have been nice to search with the 360. Live and learn.
