Enhance your covert and intelligence operations using the Newcon Optik SENTINEL LRF 640 Thermal Rangefinder Bi-Ocular. This versatile device combines high-resolution thermal imaging and laser range-finding capabilities. Designed as a bi-ocular optic, it reduces fatigue by allowing you to conduct observations with both eyes. Its 640 x 512 uncooled sensor, combined with wide field optics, allows you to view a thermal profile of the scene at a 9 Hz refresh rate, and detect and recognize targets and their activity at ranges up to 1.86 miles. This infrared camera is enhanced with a built-in 1.55µm eye-safe laser rangefinder and a compass, delivering precise target distance, azimuth, and elevation to the internal display. In addition, the bi-ocular generates a video output in NTSC or PAL formats that can be delivered to an external monitor or a recording device. To provide years of service and to withstand challenging conditions and adverse weather, this thermal rangefinder is outfitted with a durable, waterproof housing that is ergonomic and provides a standard 1/4"-20 socket for mounting on a tripod for long-term observations. It also offers eyepieces with diopter adjustments and rubberized eyecups.
