ATN Mars LT 320 2-4x

• 320x240 thermal sensor: The 12 μm sensor gives this scope enough detail for confident target detection and recognition at practical hunting distances while keeping the unit lighter and simpler than larger, more expensive thermal systems.
• 2-4x magnification range: The low starting magnification helps with scanning and close-to-medium-range shooting, while the higher setting adds image scale for more precise shot placement without making the scope bulky.
• 60 Hz refresh rate: A faster refresh rate keeps moving animals and panning views looking smoother, which makes tracking easier when targets are crossing or when scanning from a vehicle or blind.
• 10-hour internal battery: The built-in Li-ion power system supports long evenings in the field without external packs or frequent battery changes, helping keep the rifle setup clean and balanced.
• 30 mm ring compatibility: The Mars LT is designed for standard 30 mm rings, making it easier to fit on a wide range of hunting rifles with familiar mounting hardware.

About the ATN Mars LT Series

ATN Mars LT is ATN’s lightweight thermal riflescope family, built for shooters who want the practical advantages of thermal imaging in a more streamlined format. ATN categorizes the Mars LT family as thermal riflescopes, and the series is aimed at hunting and field use where reduced weight, straightforward controls, and dependable runtime matter more than an overloaded feature set. Across the line, the scopes use USB Type-C charging, a stated battery life of 10 or more hours, and compatibility with standard 30 mm rings, which helps them fit naturally into conventional rifle setups.

The series includes both 160×120 and 320×240 sensor versions, with all models operating at a 60 Hz refresh rate for smoother viewing when scanning or following moving game. Shared features include White Hot and Black Hot viewing modes, multiple reticle patterns, and One Shot Zero, all chosen to keep thermal shooting efficient in the field. The Mars LT line is also described as weather resistant, reflecting its role as a practical hunting optic intended for regular outdoor use rather than bench-only shooting.

About the ATN Mars LT 320 2-4x

The ATN Mars LT 320 2-4x is a compact thermal riflescope built around a 320x240 sensor with a 12.00 μm pixel pitch and 60.00 Hz refresh rate. In practical use, that combination gives the scope a responsive image that is easier to follow when animals are moving and more comfortable to scan with over wider areas. Its 715.00 m detection range makes it suitable for locating heat sources well beyond normal shooting distance, while the 2-4x magnification range keeps the image useful for both observation and shot placement at short to medium ranges.

The scope uses a Micro - HD display with 1280x720 resolution, giving the shooter a clear viewing screen for reticles, target outlines, and menu information. ATN’s multi-reticle setup adds flexibility for different rifle and load combinations, and the digital thermal format avoids dependence on ambient light, which is especially useful for night hunting, pest control, and spotting animals in cover. With 90.00 mm eye relief, the scope provides a more forgiving shooting position on centerfire rifles, while the aluminium housing helps keep weight to 650.00 g without making the optic feel fragile.

Field practicality is a major part of this model’s appeal. The internal Li-ion battery is rated for 10.00 h, reducing the need for spare cells during long sessions, and the scope is both waterproof and fogproof for use in damp or changeable conditions. Its 292.00 mm length and standard 30 mm mounting format make it easier to integrate into a conventional hunting rifle setup than many bulkier thermal optics.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and the company focuses on night-vision, thermal-imaging, and digital day-and-night optics. It is a United States company headquartered in Doral, Florida, and its catalog spans traditional image-intensifier night vision, digital night vision, and thermal devices for hunting, observation, and tactical use. That broad specialization is relevant here because ATN has spent decades building products around electronic imaging rather than adapting conventional daytime optics.

In recent years, ATN expanded its digital platform with products such as the X-Sight II HD series introduced in 2015, followed by optics using the Obsidian 4 Dual Core platform in 2018. The company also introduced the ThOR LT thermal scope series in 2020. This background helps explain ATN’s emphasis on integrated digital features, compact thermal systems, and user interfaces designed around practical field use rather than purely traditional scope design.
