Pay the extra 300 bucks and get the rattler v2 - AGM Global Vision Taipan TM10-256 Thermal Imaging Monocular

Monocular works decent inside of 100 yards but it only shows animals. It doesn’t show any of the background of what’s around the animal or heat that it’s picking up. Honestly just pay a couple extra hundred bucks and get the rattler v2 scope. It works well as a spotter and you have the option of putting it on a rifle.
