This will be for those who live in the great white north, or hunt when it's real cold. Few weeks ago when the wife and I went hunting right after the last thaw we had our ProPointers started acting up. I would turn it on and make one sweep to find the target and it would go bonkers. Sounded like a police siren till I turned it off and back on, and then it would do it again. I changed to new batteries, still did it. I haven't had the chance to go out again. I was just wondering if any of ya'll had this happen.
