ATN's Thor HD Thermal Scope is powered by Obsidian Core T II technology. It features a MicroSD card with 64GB's which you can record videos and photos, built in Wi-Fi, bluetooth, smooth zoom, and GPS Geotag. Included is an E-compass that lets you know exactly what direction you need to go, a built-in Gyroscope and Image Stabilization which helps steady your view. The smart range finder uses only two clicks to help get your reticle on target, while Profile Manager saves all the ballistic and zeroing-in data.
