The EDRP2-R650R is a multifunctional thermal imaging sight engineered for long-range observation and precision targeting. It combines a 640×512 / 12 μm VOx uncooled detector, 50 mm F1.0 optics and a 1024×768 OLED display with a built-in 1000 m laser rangefinder, ballistic calculator and electronic compass — giving the operator target detection, range data and firing solutions in a single device.
With a detection range of up to 2600 m and thermal sensitivity of ≤20 mK, the EDRP2-R650R performs in complete darkness, through smoke and in adverse weather, making it suitable for observation, security and precision shooting applications.
Key Features

Ballistic Calculation and Rangefinding
The integrated ballistic calculator turns measured distance into a firing solution. Operators configure a profile with ballistic coefficient, bullet weight, muzzle velocity, bullet diameter and length, zero distance, sight height, rifling direction and twist, plus current temperature, pressure and humidity. Combined with the 1000 m laser rangefinder, the sight provides fast, repeatable holds at extended range.
Display and Interface
A 1024×768 OLED display delivers high-contrast imagery. The on-screen menu provides profile management, reticle selection, image brightness, image contrast, DDE digital detail enhancement, OLED brightness, ballistic calculation, electronic compass and advanced settings. Units can be switched between metres and yards.
Controls and Layout
The device uses a four-button panel plus an encoder: power, recording, mode and laser ranging, with a focusing handwheel, diopter adjustment and a rubber eyecup. A standard mount is supplied and the unit runs on a single field-replaceable 18650 battery accessed through the battery compartment.
