I'll be starting to modify my Pelican 1120 soon and was considering making some sort of shutter hood to keep rain and snow off of the shutter lens. I've been noticing that probably most completed cam units that I've seen pics of don't use one. I don't want to make more work for myself if it's not necessary and was wondering what the general feeling is of having or not having them is. I could see using one as being a problem depending on how/where it was mounted as snow could accumulate and hang down off of it but I can also see it benefiting as well. Not sure what to do. Suggestions/opinions?
