ATN Thor 4 640 Thermal Rifle Scope, Black Anodized, 1.5-15x, Multi-Reticle, 640x480 Resolution with Built-in Rangefinder

The ATN Thor 4 640 thermal rifle scope brings thermal imaging power to long-range hunting and precision shooting without relying on ambient light. This 1.5-15x magnification scope pairs a 640x480 thermal sensor with ATN's Obsidian IV Dual Core processor to deliver clear, detailed target acquisition in complete darkness, fog, smoke, and heavy brush—conditions where conventional scopes fall short. Built on a 30 mm standard ring mount, it integrates seamlessly into most rifle platforms and ships ready to attach.

The Thor 4 640 is built for hunters and shooters who need reliable thermal detection across variable distances. Its 1050-meter human detection range and 530-meter recognition capability let you identify targets reliably before commitment, while the integrated rangefinder calculates ballistics on the fly—critical when hunting unfamiliar terrain or switching between game. The onboard ballistic calculator factors wind, elevation, and distance, feeding data directly to your scope's reticle. Multiple reticle patterns and color options let you dial in the visual style that works best in your thermal image.

Smart features keep the Thor 4 practical in the field. WiFi and Bluetooth connectivity stream your scope view and controls to iOS and Android devices, letting you glass from behind cover or hand the phone to a spotter. The 3D gyroscope, accelerometer, electronic compass, and barometer build environmental awareness into your shot planning. Recoil-Activated Video automatically records the moment of impact, preserving your hit for later review. Up to 16+ hours of battery life from the internal lithium-ion cell covers a full hunt, and the weatherproof design handles rain and temperature swings without flinching.

The 1280x720 HD micro display gives you a sharp sight picture, while the 90 mm eye relief accommodates various shooting positions and recoil-sensitive rifle setups. You can record video at 1280x960 resolution in 30 or 60 fps to a microSD card (up to 256 GB), and the built-in microphone captures audio for hunt documentation. Backed by a 3-year warranty, the Thor 4 640 is a serious optic for serious hunters.

Specifications

Frequently Asked Questions

What calibers and rifle types is the ATN Thor 4 640 compatible with?

The Thor 4 640 mounts via 30 mm standard rings, which are included. This allows compatibility with the vast majority of rifle platforms that accept standard 30 mm ring mounts. Verify your rifle's mounting system accepts Picatinny or Weaver rails with 30 mm spacing before purchase.

How far can I accurately detect and identify targets with this thermal scope?

The Thor 4 640 can detect humans at 1050 meters, recognize human shapes at 530 meters, and identify specific features (gear, posture) at 330 meters. Detection range varies with ambient temperature contrast and atmospheric conditions; these figures represent typical performance under favorable field conditions.

Can I stream the scope view to my phone while hunting?

Yes. The Thor 4 640 features WiFi connectivity and companion apps for iOS and Android that let you stream the thermal image and control scope functions remotely. This is useful for spotting, recording, and sharing what the scope sees without repositioning yourself at the eyepiece.

How long does the battery last in the field?

The built-in lithium-ion battery delivers 16+ hours of runtime per charge, enough for a full day of hunting or range work. Battery life depends on magnification level, display brightness, and accessory use (WiFi, Bluetooth, recording).
