ATN OTS LT 320 2-4x

• 320x240 thermal sensor with 12 μm pixels: Delivers a clearer thermal image than entry-level sensors, helping the user separate animals, people, and background detail more confidently at practical observation distances.
• 2-4x magnification range: Starts wide enough for scanning and tracking movement, then adds extra reach for checking heat signatures without carrying a larger thermal device.
• 60 Hz refresh rate: Keeps motion looking smoother when panning across fields, woodland edges, or search areas, which makes moving targets easier to follow.
• Obsidian LT Core with White Hot and Black Hot modes: Gives the user a simple thermal viewing system with two proven display palettes, so the image can be adapted to terrain, contrast, and personal preference.
• Compact body with 9+ hour internal battery: Combines handheld portability with long operating time, making the monocular practical for extended observation, recovery work, and patrol use without frequent charging.

About the ATN OTS LT Series

The ATN OTS LT series is a family of handheld thermal scanners built for users who want practical thermal observation in a lighter, simpler format than a full-featured smart optic. Introduced in 2020, the series uses the ATN Obsidian LT Core and focuses on straightforward field use rather than menu-heavy operation. Across the range, ATN combines a compact ergonomic housing with a simple graphical interface, so the monocular is quick to learn and easy to handle during scanning, recovery, and search tasks.

The series includes both 160- and 320-resolution variants, allowing users to choose between a more basic entry point and stronger image definition for better target recognition. Shared features such as White Hot and Black Hot viewing modes and an internal battery rated for more than 10 hours support the OTS LT’s role as a dependable observation tool for hunting support, game recovery, and search-and-rescue work. In ATN’s thermal lineup, the OTS LT series stands out for its emphasis on portability, clean controls, and useful thermal performance in a dedicated handheld format.

About the ATN OTS LT 320 2-4x

The ATN OTS LT 320 2-4x is the lower-magnification 320-sensor model in the series, designed for users who need a thermal monocular that balances wide-area scanning with enough magnification to inspect a heat source more closely. Its 320x240 sensor with 12.00 μm pixel pitch gives this model a meaningful step up in image definition over basic thermal units, while the 60.00 Hz refresh rate keeps the view fluid during panning and target tracking. For practical field use, that means a more natural image when searching hedgerows, field edges, woodland trails, or open ground.

The 2-4x magnification range is especially useful for handheld observation because it starts with a broader view than higher-base-power models, making it easier to locate movement quickly, then adds extra image scale for confirmation. A 19.00 mm objective lens and 1280x960 Micro - HD display support a clear viewing experience, while the 535.00 m detection range gives the monocular enough reach for spotting heat signatures well beyond close observation distances. ATN’s White Hot and Black Hot modes let the user adapt contrast to terrain and conditions.

In use, the monocular remains practical thanks to its 560.00 g weight, compact 195.00 mm length, and 9.00 h Li-ion battery life. The weather-resistant, fogproof design and operating range of -28°C to 48°C make it suitable for year-round outdoor work, whether the task is game detection, recovery, general surveillance, or search support.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and focuses on night-vision, thermal-imaging, and digital day-and-night optics. The company’s product range spans traditional image-intensifier night vision, digital night vision, and thermal devices, giving it a broad base in electro-optics rather than a narrow focus on one technology alone. ATN is a United States company headquartered in Doral, Florida.

Within this category, ATN is particularly known for bringing digital features into field optics, including its 4K-resolution Smart HD systems and the Obsidian 4 Dual Core platform introduced in 2018. That background matters here because the company’s thermal and digital products are built around in-house electronic platforms and user interfaces, not just optical hardware. For handheld thermal observation, ATN’s experience in combining sensors, displays, and practical field controls is central to the character of the OTS LT line.
