So, my standard cheap Suunto A-30 compass dried out... and I'm just starting to get into NH winter hiking. I've found limited information in a quick Google search. Do compasses freeze in the winter? It's a bit fuzzy what fluid they fill them with, some sort of alcohol or anti-freeze, and they only give very general information about the actual temperature range they operate in.

Seems the same cold conditions that could damage my cell phone could damage a compass? Any suggestions? Do I need to actually carry it around my neck and share body warmth with it? Is there some brand or model that performs better in the winter? Am I worrying over nothing, and can I just keep a cheap one where I can easily get to it?

Thanks.
