The AGM Secutor LRF-C 75-640 Thermal Clip-On (AGM part no. SECU75-640C-LRF) is a compact thermal imaging system with a built-in laser rangefinder. It clips in front of a rifle scope with up to 10x magnification, turning a day optic into a thermal setup without special tools. A 12-micron thermal detector and a 1024×768 OLED display give a clear image through darkness, fog, smoke, rain, snow and brush. The rangefinder shows the exact distance to the target on the monitor. The 75 mm lens suits medium-range work, and AGM Global Vision rates detection at 3,800 meters.
