I run game cameras year round. usually have at least 5 out at all times.
The new M80 black flash moultries will last about 4 months on a set of AA batteries and take over 4k pictures and still have a little battery life left.
I have ten thousand acres to hunt 20 minutes from home, and another five thousand a little over a hour away. IMPOSSIBLE to scout all that area if you work or have a family. I get deer on camera every year that are never taken or even seen by anyone.
I also use them for to help my with trapping. If im getting a lot of predators on camera thats where I concentrate my trapping efforts at and it saves me lots of wasted time and effort.
When you want better service from a online gun seller and someplace that actually will talk to you on the phone unlike "Duds" gun shop, try them.
