The Burris BTC35 v2 Thermal Clip-On (Burris part no. 300622) is a thermal imager that works as a handheld tracker or clips in front of a traditional riflescope to turn it into a thermal optic. A 400 x 300 sensor behind a 35mm F1.0 lens gives a 7.8 by 5.9 degree field of view, and 1x, 2x and 4x zoom let you scan wide and then punch in on a target. Burris says it can identify thermal signatures out to 750 yards, which is the kind of reach night hunting calls for. Five color palettes let you pick the look that reads best in the conditions you are working. At 16.2 ounces it stays manageable on a rifle or in the hand.

Key Specifications

• The sensor resolution is 400 x 300, a 12-micron VOx sensor with a 50 Hz refresh rate for a smooth image on moving targets.
• The lens is a 35mm F1.0 with manual focus, a fast aperture that gathers heat signature detail with a compact objective.
• Zoom steps are 1x, 2x and 4x, so you can scan at low power and then magnify a target without changing optics.
• Five palettes are built in: black hot, white hot, red hot, green hot and blue hot, so you can match the display to the terrain.
• The field of view is 7.8 x 5.9 degrees, wide enough to sweep a field at 1x.
• Power comes from two CR123 / 16340 batteries for a rated run time of at least 2 hours at 25 degrees C.
• The eyepiece is a M33.5 x 0.75 thread for the SmartClip system, with a 1/4-20 interface for an M1913 QD mount, so it attaches in front of a riflescope.
