I borrowed this from a friend to try on a gopher digging in my yard at night. Seems pretty cool. Has adjustable cross hairs and mounts like a Red Dot on a picatinny. In the picture you can see the motor on my band saw that had been run a hour earlier still lit up. Taking pics of the screen does not work so good. Seems like the camera pics up some waves that you eye does not see? Should be good for small vermin out to 30-40 yards I think. Will update soon.
