The Sightmark Wraith 2 LRF 640 is a 2-16x40 thermal riflescope built around a 640x512 Vanadium Oxide sensor with thermal sensitivity under 20mK, which can help subtle temperature differences show up as a cleaner image. A built-in Class 1, 905 nm laser rangefinder ranges targets from 5 to 1,000 yards and puts the distance on the display, so you don't need to reach for a separate device. The image runs at 60 fps, and the red dial zooms up to eight times the starting magnification. Sightmark lists a detection range of 2,730 yards on a 4.9 ft target.

An OLED eyepiece shows the thermal image along with battery level and measured distance, and the rubber eyecup blocks display light from leaking around your eye. Pressing the red control dial cycles through color palettes, and you can pick from White Hot, Black Hot, Rainbow, Green Hot and Iron Heat to suit the ground you are scanning. It runs on a removable, rechargeable 18650 lithium-ion battery that you swap by hand without tools, and two batteries and a separate charger are included. The integrated Picatinny mount attaches to a Picatinny rail, and a removable side Picatinny rail takes accessories such as a laser or an external battery pack.
