Guide TR 650-A Thermal Riflescope

The Guide TR 650-A delivers 640×512 thermal resolution with ≤20mK sensitivity through a fast 50mm F1.0 lens — the same proprietary VOx detector technology that Guide manufactures for brands across the thermal industry, offered direct with a 10-year warranty and a US-based service center in Texas.

Key Features

• Proprietary 640×512 @ 12μm VOx Sensor — Guide designs and manufactures its own uncooled vanadium oxide detectors, the same core technology found in thermal optics from well-known industry brands. The TR 650-A puts this detector directly in your hands with ≤20mK NETD sensitivity — resolving fine thermal detail like bark texture, fence lines, and animal outlines that 17μm sensors and less sensitive units miss entirely.

• 50mm F1.0 Germanium Objective — The fast F1.0 aperture maximizes infrared energy collection, pushing the detection envelope to 2,600 meters. At practical hunting distances, this translates to brighter imagery and better contrast in humid or foggy conditions. The 8.8° × 7.0° field of view keeps situational awareness strong while you scan open terrain.

• 1024×768 AMOLED Display — A 0.39-inch AMOLED panel with true blacks and seven selectable color palettes (White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, Sepia). The high pixel density and AMOLED contrast make the display easy to read in any ambient light condition, from full dark to twilight.

• 3x – 23.2x Magnification Range — Start at 3x native for wide-field scanning and zoom smoothly to 23.2x for positive identification at distance. The 50Hz refresh rate maintains a fluid, lag-free image through the full zoom range — critical when tracking moving targets across open ground.

• 8-Hour Battery on Standard 18650 Cells — One replaceable 18650 battery delivers a full night of hunting. No proprietary battery packs or adapters — carry a spare in your pocket and swap in seconds. The USB-C port handles charging and data transfer when you need it.

• 32GB Onboard Recording — Capture photos and video with audio directly to internal storage. WiFi and Bluetooth connectivity stream live to the TargetIR app for shared viewing, remote zeroing assistance, and firmware updates.

• IP67 Weatherproof, .300 Win Mag Rated — Fully sealed against dust and rated for temporary water immersion. Tested for the sustained recoil of magnum rifle cartridges. The operating range of -30°C to +50°C covers every hunting condition from late-season cold snaps to summer predator calls.

Ideal For

Night hog hunters who need reliable detection at range and enough sensor resolution to distinguish targets in groups. The 50mm lens extends your detection range past most competitors in this price class, and the 640×512 sensor resolves the detail needed for confident shot placement — not just "something warm is out there."

Predator and coyote hunters working open terrain at night. The wide base magnification and smooth zoom let you scan quickly and close the loop on called animals. The 50Hz refresh keeps the image stable during fast panning across fields and senderos.

Value-conscious thermal shooters who understand the OEM landscape behind thermal branding. Guide produces the detectors inside many higher-priced thermal scopes — the TR 650-A delivers that same sensor technology with direct manufacturer support, a 10-year warranty (the longest in the category), and a US service center in Texas.
