The Burris BTC35 V3 Thermal Clip-On is a perfect addition to any hardcore predator or hog hunter’s arsenal. This easy to use device can be used to convert a traditional riflescope into a thermal optic or be used as a handheld monocular. The heart of the BTC35 V3 is an advanced 400x300 VOX Sensor with a 50HZ Refresh Rate and a 12µM Pixel Pitch. The powerful sensor is perfectly paired with a high performance 35mm F1.0 lens. This combination allows the BTC35 V3 to pick up heat signatures from 750 yards away. Heat signatures are projected onto a 1024x768 OLED display and are viewable in nine distinct color pallets – white hot, black hot, red hot, green hot, blue hot, amber, sepia, inferno, iron – allowing the BTC35 V3 to adapt to changing conditions or user preferences. The BTC35 V3 attaches to the host optic with either a M33.5 x 0.75 threaded eyepiece or a 1/4-20 interface for M1913 QD Mount. In addition, the BTC35 V3 uses 2x CR123 batteries that deliver 2+ hours of runtime, and can be quickly swapped in the field.
