ATN Mars 4 384 7-28x

• 384x288 thermal sensor: The sensor gives this thermal riflescope a practical balance of image detail, refresh speed and file size, making it well suited to spotting heat signatures and tracking movement without the heavier cost and data load of higher-resolution units.
• 7-28x magnification range: This configuration is aimed at longer observation and shot placement, giving the user enough base magnification for detail work while extending to 28x for more precise target identification at distance.
• 60 Hz refresh rate: A faster refresh rate helps the image stay smoother when scanning, following moving animals or panning across terrain, which makes target tracking more natural than on slower thermal systems.
• Obsidian IV Smart HD platform: ATN’s processor adds field-use functions such as ballistic calculation, one-shot zeroing, profile management and video features, so the scope does more than simply display a thermal image.
• 18-hour internal battery: Long battery life reduces the need for external power packs during extended hunts or night sessions, helping keep the rifle setup cleaner and easier to manage in the field.

About the ATN Mars 4 Series

ATN Mars 4 is the company’s fourth-generation Smart HD thermal riflescope series, built for hunters and shooters who want a thermal sight with both observation capability and integrated digital tools. Across the range, the series combines 384x288 or 640x480 thermal sensors with a 60 Hz refresh rate, giving users a choice between different levels of image detail, objective sizes and magnification ranges depending on terrain and expected engagement distance.

A defining part of the series is the ATN Obsidian IV dual-core thermal processor, which turns the Mars 4 into more than a conventional thermal optic. Shared functions include a ballistic calculator, one-shot zeroing, Recoil Activated Video, Wi-Fi streaming, a smart rangefinder, an electronic compass and profile management. In practice, that makes the series suitable for users who want to record hunts, save multiple rifle profiles or simplify holdover decisions in the field. The Mars 4 line sits as a mature Smart HD thermal platform in ATN’s lineup, with a strong emphasis on combining thermal detection, digital convenience and rifle-mounted usability in one housing.

About the ATN Mars 4 384 7-28x

The ATN Mars 4 384 7-28x is a thermal riflescope configured for users who prioritize higher native magnification and long-distance thermal observation over wide-area scanning. Its 7-28x magnification range and 75.00 mm objective lens make it particularly relevant for open ground, field edges and other situations where identifying a heat source at longer distance matters more than maintaining the broadest possible field of view. With a stated 3000.00 m detection range, it is built to pick up heat signatures far beyond normal shooting distances, giving the user more time to assess movement and direction before closing the decision.

The thermal core uses a 384x288 sensor with 60.00 Hz refresh rate and 60.00 mK NETD. In practical terms, that combination supports smoother tracking and usable thermal contrast when scanning moving targets or shifting between warmer and cooler backgrounds. The 1280x720 Micro - HD display presents the image at a higher viewing resolution than the sensor itself, helping menus, reticles and recorded content appear cleaner to the eye during extended use.

As part of the Smart HD concept, this model adds more than thermal imaging alone. Video recording and image capture allow the user to document observations or shots, while WiFi connectivity supports streaming and file handling within ATN’s connected ecosystem. The Multi reticle setup gives flexibility for different shooting preferences, and the 18.00 h internal Li-ion battery supports long sessions without changing cells. An aluminium housing, waterproof and fogproof construction, and an operating range of -28°C to 48°C round out a design intended for sustained outdoor use.

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’s product range spans traditional image-intensifier night vision, digital night vision and thermal devices, giving it a broad base in electro-optical shooting and observation equipment. ATN later established its headquarters in Doral, Florida.

A major part of ATN’s identity is its work in digital optics. The company introduced the X-Sight II HD digital day-and-night sight series in 2015, and in 2018 it launched products built around the Obsidian 4 Dual Core platform. That background is directly relevant to the Mars 4 family, which combines thermal imaging with onboard processing, recording and connected functions rather than treating the optic as a simple viewing device.
