Atn Corp Thor 4 640 4-40x Thermal Riflescope

ATN Thor 4 640 Thermal Riflescope

The ATN Thor 4 640 is a smart HD thermal digital riflescope built for hunters and shooters who need reliable target detection in total darkness or adverse weather. It combines a 640x480 thermal sensor with the Obsidian IV dual core processor to deliver clear imagery across a 4-40x magnification range. Integrated video recording saves footage directly to an internal micro SD card for later review.

Hunters needing long-range thermal detection

This riflescope suits hunters who require variable magnification up to 40x for identifying targets at extended distances. The Spin to Zoom wheel and glove-friendly tactile buttons allow quick adjustments in the field. Buyers who need a traditional optical daytime scope or a lighter handheld thermal monocular for scanning should consider other device types.

640x480 thermal sensor resolution

The 640x480 sensor resolution determines the level of thermal detail available for target identification and recognition at range. Higher resolution provides clearer outlines of heat signatures compared to lower-resolution cores. This specification is the primary factor in deciding whether the Thor 4 640 meets the detection requirements for a specific hunting application.
