The Guide TU635LS is a top-tier model in the Guide TU 3.0 Series, powered by the next-generation APEXVISION infrared imaging system. It features a 640x512@12μm thermal sensor with an impressive <15mK NETD sensitivity, delivering ultra-clear thermal images in challenging conditions. The powerful lens system offers a 1800m detection range, while the built-in lens laser rangefinder gives fast, accurate distance readings up to 1200m, ideal for precision targeting at extended distances.

Rugged Construction: Designed for rugged use, the TU635LS features an IP68 waterproof rating and a durable metal housing built to withstand recoil, moisture, and demanding field conditions.

Mounting: Includes a Quick Release Scope Mount for fast, repeatable attachment and removal, secured to a torque specification of less than 2.5N·m (22.13in-lbs) to protect the mount and rail.

True Shutterless Performance: Advanced Shutterless 3.0 technology eliminates image freezing and audible clicks, delivering smooth, real-time viewing without interruption in the field (a shutter module is retained to maintain optimal image quality during startup and in extreme temperatures).
