The ATN OTS LT 320 thermal monocular brings serious thermal imaging capability to your hunts, search-and-rescue ops, or nighttime scouting missions—without the bulk or battery dependence of older gear. This 6-12x zoom, 35mm thermal monocular delivers a 320x240 resolution image through the Obsidian LT Core platform, built around a design that prioritizes what matters: lightweight ergonomics, built-in battery life that outlasts the field day, and the kind of thermal clarity that makes spotting game or subjects genuinely easier instead of a frustration.
Built for the operator who needs one hand free and doesn't want to think about swapping batteries every few hours, the OTS LT 320 packs a proprietary internal battery with a power management system designed to keep you working when it counts. The monocular fits naturally in your palm, with 25mm eye relief for a comfortable sight picture whether you're glassing from a blind, scanning terrain on foot, or conducting SAR operations in darkness. USB-C charging means you're not hunting down proprietary batteries in the field—just grab any modern charger and go.
This is the no-nonsense tool for anyone doing serious thermal work at night: hunters verifying game presence before the stalk, search-and-rescue teams covering ground faster, property managers checking perimeter security, or backyard observers documenting wildlife. The 35mm lens and 6-12x magnification give you solid range and detail without the weight penalty of larger optics. If you need more runtime, ATN's Extended Battery Pack (sold separately) will stretch your operating window to 15 hours—a real advantage on long operations.
