ATN Mars LT 320 5-10x

• 320x240 thermal sensor with 12 μm pixel pitch: delivers a cleaner thermal image than entry-level sensors, helping the scope separate animals from background clutter and making target detection more reliable at longer distances.
• 5-10x magnification range: gives the ATN Mars LT 320 5-10x enough base magnification for deliberate shooting while still allowing extra zoom when the target is farther out or needs more precise placement.
• 60 Hz refresh rate: keeps motion looking smoother when scanning, tracking moving game, or panning across uneven terrain, which makes the image easier to interpret in real hunting conditions.
• 1280x720 Micro-HD display: presents the thermal image on a sharp internal screen that supports more confident aiming and easier reticle use than a lower-resolution display.
• Lightweight 30 mm-ring format: at 650.00 g and built for standard 30 mm rings, the scope fits more easily into familiar rifle setups without adding the bulk often associated with thermal hunting optics.

About the ATN Mars LT Series

The ATN Mars LT series is ATN’s streamlined family of thermal riflescopes, built for shooters who want thermal capability in a format that feels closer to a conventional day scope. A defining trait of the series is its compatibility with standard 30 mm rings, which simplifies mounting and makes the transition to thermal hunting optics less complicated for rifles already set up around common scope hardware.

Within the family, ATN offers both 160×120, 17-µm models and 320×240, 12-µm models, all running at a 60 Hz refresh rate. The series also shares practical core functions such as White Hot and Black Hot viewing modes, multiple reticle patterns, and One Shot Zero, giving users a straightforward thermal sighting system without the heavier feature load of larger premium units. ATN positions the Mars LT line as a lighter, simpler thermal riflescope range for hunting and field use, with USB Type-C charging and a stated battery life of 10 or more hours supporting longer outings.

About the ATN Mars LT 320 5-10x

The ATN Mars LT 320 5-10x is configured for shooters who need more reach from a compact thermal riflescope. Its 320x240 sensor with 12.00 μm pixel pitch gives it a meaningful advantage in image definition over lower-resolution thermal options, while the stated 1620.00 m detection range supports early spotting before a target closes into shooting distance. In practice, that makes this model well suited to open ground, field edges, and night hunting where identifying heat signatures quickly matters.

The 5.00 x to 10.00 x magnification setup favors deliberate observation and shot placement. At the lower end, it still provides enough field coverage for scanning likely approach routes, while the higher setting helps when a smaller target or a longer shot demands more precise aiming. The 50.00 mm objective lens supports the scope’s detection capability, and the 1280x720 Micro - HD display gives the shooter a crisp viewing surface for reading the thermal scene and using the reticle with more confidence.

ATN keeps the handling practical. The scope offers 90.00 mm eye relief, which is important on centerfire rifles, and its 650.00 g aluminium housing keeps overall rifle weight under better control than many bulkier thermal systems. A stated 10.00 h internal Li-ion battery life reduces the need for external power solutions, while waterproof and fogproof construction helps the scope stay usable in damp, cold, and changeable weather. For hunters who want a thermal scope with useful range but a familiar, low-bulk form factor, this model is one of the more focused configurations in the Mars LT line.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and it focuses on night-vision, thermal-imaging, and digital day-and-night optics. The company is now headquartered in Doral, Florida and has built its reputation around electronic optics rather than traditional glass-only sporting scopes. That background is especially relevant in thermal and digital sighting products, where sensor integration, onboard processing, and display performance matter as much as the external housing.

ATN’s product range covers traditional image-intensifier night vision, digital night vision, and thermal imaging devices. In its digital optics segment, the company introduced 4K-resolution Smart HD systems for day-and-night use, and in 2018 it introduced products built around its Obsidian 4 Dual Core platform. ATN also launched the X-Sight II HD series in 2015 and later introduced the ThOR LT thermal scope series in 2020, reflecting a long-running focus on practical electronic optics for hunting and observation.
