ATN ThOR 320 4.5x Fast Thermal Imaging Weapon Sight Product Info

The ATN ThOR 320 4.5x Thermal Tactical Sight is an advanced thermal optic designed for use by law enforcement professionals and the military, equipped with state of the art imaging features and an intuitive digital interface. These powerful ATN ThOR 320 4.5x Thermal Imaging Sights are completely digital, with no springs or screws to create a loss of zero. The 800 x 600 OLED color display combines with the fast, 30hz frame rate to give you impeccable night and thermal vision that completely disregards darkness, camouflage, and even fog to bring you real-time intel in high definition. Since the display of the Advanced Technologies Network ThOR 320 4.5x 30hz Thermal Imaging Scope is in full color, you can select four different reticle shapes in black, green, white, or red for a high contrast aiming point. In addition, these thermal imaging devices let you adjust polarity with a single button press; all these settings are controlled by the intuitive digital menu, which also controls windage and elevation for the ATN ThOR 320 800x600 OLED Digital Thermal Imaging Sight.

The Advanced Technology Network ThOR 320 Digital 4.5x Thermal Weapon Sight packs a powerful 4.5x optical E-zoom function that is ideal for night hunting and surveillance under the cover of darkness. ATN has made the ThOR 320 incredibly responsive and efficient: the device can boot up in approximately five seconds, and it can run for up to eight hours on three 3v CR123A batteries. Compact and lightweight (less than a kilogram, even with batteries installed), the ATN ThOR thermal sight is completely waterproof and made with mil-spec lenses for rugged durability. The ATN ThOR 320 4.5x Thermal Imaging Device works equally well as a handheld thermal sight and as a weapon-mounted thermal scope, and it comes with a Picatinny quick release mount for secure mounting to a variety of firearms and accessories. A professional-grade digital thermal device that's always accurate and always bright, the ATN ThOR 320 Digital OLED 4.5x Thermal Sight w/ Picatinny Mount gives you the advanced technology that ATN is known for in a compact but tough package.
