How do the digital cams hold up to the cold? Our hunting crew has had 3 35mm go bad after the temps drop down to 0 deg.F. They are a stealth cam,moultrie,and Trailtimer.On some the camera wont take picks even when they are out of the cam(with new batts.) and on others the internal electronics are messed up.The all worked good untill they got cold. How do the digitals handle the cold? I dont want to spend $ on digital if the electronics cant take the cold.Thank you.
