Hummingbirds seem to be cold sensative. When I use mine it stays in the cab of the truck on the ride there and back. I keep it in a small little cooler to keep it a little warmer. A ice tent w/ a heater going is a plus to keep it operating good. If you dont have a tent keep it in the direct sunlight to keep it from freezing up. A cover w/ hand warmers is a good idea from tubedude. I use a Lowerance now and dont have to worry about the cold messing up the finder. Good luck!!
