I put out two Truth Cam 35's last year. They took thousands of pics. Then when it got cold around ML season, they both quit taking pics.
I just put them out again this past Friday. The batteries said 70 percent yet so I left them in. I will see if they are working one night this week. If they are not, I will try fresh batteries. If that don't work, a call to Primo's may be in order.
