Great scanner for the money - AGM Global Vision Taipan TM10-256 Thermal Imaging Monocular

This unit is great for scanning and is a relatively small price to pay for being able to detect animals quickly and at range. Deer and hogs are pretty easy to ID out to a couple hundred yards if you have some experience and know their body shapes and movements. Even if you can't ID them at least you'll know somethings there when you might have missed them with nightvision or lights. It's also way better than trying to look around with the optic on your rifle. If you have a large property to hunt it's a big time saver or if you just wanna see what critters are in your yard at night it's good for that too.
