ATN night spirit Gen 2 monocular. Is in great condition and works well under low light conditions. I have Gen 3 equipment that I have compared this to in the field and its very good. Especially with some additional IR lighting. Is hand held only, although can be mounted on tripod.Operates on a single AA battery.Has an inbuilt IR unit for close up work. I use a mag lite with IR filter for greater distance. For beginner into night vision is a great unit and I am happy to recommend it. If you live in queenstown area you are welcome to make contact to try out before you buy. Very important with Night vision equipment.
