well try contacting the company and see what suggestions they tell you
you can try putting in near a warm place , like a heater vent to help dry it real good, just NOT on top of a heat source, just close by
electronic's are funny things when they get wet!

good luck
and last, if you only use for bow hnting a smaller one will work just as well, and now a days lots of decent one's out there on sale from time to time for under a 100 bucks too!
