ATN Thor 4 640 Thermal Rifle Scope - 2.5-25x Multi Reticle, 640x480 Resolution, Rangefinder, Black Anodized (Model: TIWST4643A)

The ATN Thor 4 640 thermal rifle scope brings next-generation thermal imaging to serious hunters, tactical shooters, and predator callers who need to see what others can't—especially in low-light, no-light, or obscured conditions. Built around ATN's Obsidian IV Dual Core processor, this 2.5-25x thermal scope delivers a 640x480 thermal resolution sensor paired with a 1280x720 HD micro display, giving you crisp target acquisition and reliable performance in the field from dusk to well after dark.

What sets the Thor 4 apart is engineering built for the rigors of centerfire rifles. The housing uses hardened aluminum alloy construction with impact-resistant electronics designed to handle recoil from serious calibers. The Obsidian IV Dual Core processor runs fast and stays cool, and the scope will run for over 16 hours on a single charge—real all-day to all-night endurance. Recoil Activated Video (RAV) automatically records footage directly to your SD card when the gun fires, capturing every moment of your hunt or range session without fuss. You get a rangefinder, ballistic calculator, 3D gyroscope, 3D accelerometer, electronic compass, barometer, and smooth digital zoom to dial in shots at any distance.

The package includes an eyecup, standard scope rings, an L-shaped ring for alternative mounting, scope cover, USB-C cable, and lens tissue. The black anodized finish resists corrosion and glare. Whether you're hunting hogs in Texas, coyotes under the stars, or running low-light tactical drills, the Thor 4 640 thermal scope is purpose-built to perform when hunting seasons turn cold and daylight fades.

Frequently Asked Questions

What makes thermal imaging useful for hunting and shooting?

Thermal imaging detects heat signatures from animals and targets, making it effective in complete darkness, fog, rain, brush, and other conditions where visible-light optics fail. The ATN Thor 4 640's 640x480 thermal sensor lets you locate game and track movement regardless of light, time of day, or weather—a real advantage for night hunts, predator calling, and tactical range work.

How long does the battery last on the Thor 4 640 thermal scope?

The Obsidian IV Dual Core processor enables over 16 hours of continuous runtime on a single charge, meaning you can hunt an entire evening or run a full training day without swapping batteries. This is genuine all-day endurance for a thermal scope.

Will the Recoil Activated Video (RAV) feature work with my centerfire rifle?

Yes. RAV automatically records video to your SD card when the scope detects recoil from firing, capturing your shot without requiring manual start/stop. The Thor 4 is built with hardened aluminum and impact-resistant electronics specifically designed to handle the recoil pressures of centerfire weapons.

What rings and mounting options are included?

The scope ships with standard scope rings and an L-shaped ring, giving you flexibility in how you mount the Thor 4 to your rifle platform. A protective scope cover is also included.
