Full warranty demo unit – QUEST H35R Rangefinding Thermal Binocular 640×512 35 mm Copy

All new for 2025, QUEST binoculars deliver a comfortable and intuitive viewing experience. Unlike thermal monoculars, the QUEST binoculars allow users to use both hands and both eyes while scanning – providing a smooth and comfortable feel, just like traditional daylight binoculars. A 12 μm ≤15mK 640×512 thermal sensor captures every detail, while the Reality+ image processing algorithm delivers a vivid picture to the 1920×1200 displays (full resolution per each eyepiece). Each display has a dedicated diopter and position adjustment.

QUEST binoculars also include an easy-to-use 1,000 yard laser rangefinder that can run in either single-firing or continuous modes to show target distance on the display. The combination of an internal USB-C rechargeable battery and an auxiliary IRB-2 (18650 style) rechargeable battery allows users to hot-swap the power source and keep running all night long. The QUEST is available with a 50 mm objective lens (model H50R) or a 35 mm germanium objective lens (H35R). Each comes with everything you would expect from high-end binoculars, including a comfortable and fully adjustable binocular harness.
