ATN TIWST4641A Thor 4 640 Thermal Rifle Scope - Black Anodized, 1-10x Multi Reticle, 640x480 Resolution with Built-in Rangefinder

The ATN Thor 4 640 thermal rifle scope brings thermal imaging firepower to hunters, tactical shooters, and low-light hunters who demand a true hands-on thermal solution. Built around ATN's Obsidian IV dual-core processor, this 1-10x magnification thermal scope pairs 640x480 thermal resolution with smart rangefinding and an embedded ballistic calculator to take the guesswork out of distant shots in darkness or poor visibility. Weighing just under two pounds and constructed from hardened aluminum alloy with impact-resistant internals, the Thor 4 is engineered to handle the recoil and environmental stress of serious hunting and sport shooting.

What sets this thermal scope apart is its real working battery life—over 16 hours of continuous operation on a single charge—and its video recording capability. Connect an SD card (up to 64 GB), and you can capture hunts, training sessions, and field footage directly to the scope. The recoil-activated video (RAV) feature means you never miss documenting a moment of action. Pair the scope with your smartphone via WiFi or Bluetooth to stream a live feed, adjust settings, or pull video and images without removing the scope from your rifle. A built-in microphone, 3D gyroscope, 3D accelerometer, e-barometer, and electronic compass add tactical awareness and data logging to every mission.

The Thor 4's 1-10x zoom and multi-reticle options keep you flexible across hunting ranges and scenarios. At 830 meters, you can detect human-sized heat signatures; at 350 meters, recognize them; and at 225 meters, identify them with confidence. It mounts on any rifle using standard 30 mm rings (included), and the eyecup, lens cover, USB-C cable, and tissue round out what you get in the box. Weather-resistant construction and a 3-year warranty back your investment. This is serious thermal imaging for serious shooters—no compromise, no fluff.
