The Trijicon EO Hunter 353 IR-Hunter thermal riflescope is a compact, rugged thermal optic engineered to acquire targets in complete darkness, fog, smoke, and harsh weather—conditions where conventional scopes fail. Built in the USA to MIL-STD-810G standards, this 35mm thermal scope combines a high-resolution 640x480 12-micron thermal sensor with intuitive turret-style controls designed for gloved operation in the field. Whether you're hunting predators at night, conducting thermal reconnaissance, or training in low-light conditions, the IR-Hunter 353 delivers the thermal clarity and durability serious hunters and operators expect from Trijicon.
The 640x480 resolution and 12-micron pixel pitch deliver superior thermal image quality compared to older 17-micron systems, with 60 Hz frame rate for crisp tracking of moving subjects. Manual focus adjustment (60mm only) lets you dial in sharp images at any distance. The scope records full-resolution thermal video directly to an SD card via the integrated digital video recorder, or pairs with external recorders through the USB-C port—perfect for documenting your hunt or reviewing footage later. Enhanced rotary knobs provide faster system response with reduced lag, even when you're working in the dark.
Trijicon's Q-LOC quick-release mount technology gives you multiple secure mounting positions and the ability to attach or detach the scope reliably without tools or lights. The vertically oriented battery compartment creates a slimmer profile while maintaining solid power connections and improved durability. USB-C connectivity also lets you extend runtime with external battery packs, critical for extended field operations. The scope includes user-selectable reticles—classic crosshair and MRAD/MOA options, plus calibrated ballistic drop compensation for .223 REM, .308 WIN, and 300 BLK.

The scope includes ballistic drop compensation (BDC) reticles for .223 REM, .308 WIN, and 300 BLK, making it well-suited to those cartridges. However, the thermal optic itself is not caliber-restricted and can be mounted on any rifle with a standard Picatinny rail; you can use the crosshair or MOA/MRAD reticles for other calibers by adjusting your hold or turrets.
Yes. The integrated digital video recorder captures full 640x480 MP4 thermal video to an SD card for later playback. You can also connect an external recorder via the USB-C port if you prefer that workflow. This lets you document and share your hunt with family and friends.
The scope operates on internal batteries. The USB-C port allows you to connect external battery packs to extend runtime during extended field operations, which is valuable for long nights or multi-day missions.
The scope comes with the thermal riflescope and the Q-LOC quick-release mount. Confirm the exact contents with Bosque Outdoors at time of purchase, as accessories and batteries may vary by package.
