ATN Mars 4 640 1-10x

• 640x480 thermal sensor: The higher-resolution sensor gives the scope more image detail at base magnification, helping with target recognition and shot placement instead of showing only a bright heat signature.
• 1-10x magnification range: A true low starting magnification supports scanning at shorter distances, while the upper end gives enough image scale for more deliberate shooting without changing optics.
• Micro-HD 1280x720 display: The high-definition display presents the thermal image with a cleaner, easier-to-read view, which helps when distinguishing animals, terrain edges, and reticle hold points.
• Built-in recording and WiFi: Video capture, image capture, and wireless connectivity let the scope document hunts or training sessions and share the live view without adding external accessories.
• 18 h internal battery life: The internal Li-ion power system supports long outings with fewer interruptions, reducing the need to manage spare batteries in cold or wet conditions.

About the ATN Mars 4 Series

ATN Mars 4 is ATN’s fourth-generation Smart HD thermal riflescope series, built for shooters who want a thermal sight that combines observation, aiming, and digital tools in one unit. Across the range, the series uses the Obsidian IV dual-core thermal processor and pairs thermal imaging with features that go beyond a conventional scope, including a ballistic calculator, one-shot zeroing, and Recoil Activated Video. That makes the series especially relevant for hunting optics users who want both practical field performance and a digital record of the shot.

The Mars 4 family also supports simultaneous video recording and Wi-Fi streaming, along with a smart rangefinder, electronic compass, and profile manager. Within the series, models vary by sensor resolution, objective size, and magnification range, so the lineup covers everything from wider-field scanning setups to higher-magnification configurations for longer shots. In practical use, the series stands out for combining thermal detection capability with a familiar riflescope format, giving users a choice between 384x288 and 640x480 sensors and different optical layouts to suit terrain, target size, and expected engagement distance.

About the ATN Mars 4 640 1-10x

ATN Mars 4 640 1-10x is the wide-field, high-resolution option in the series for shooters who need a thermal riflescope that works well from close to medium distances. Its 640x480 thermal sensor and 25.00 mK NETD help the scope show smaller temperature differences, which improves separation between animals, background cover, and ground features when conditions are damp, cold, or thermally cluttered. With a 19.00 mm objective lens and a broad 32.00 ° field of view, this model is particularly useful where rapid target acquisition matters more than extreme top-end magnification.

The 1.00-10.00 x magnification range gives it flexibility. At the low end, it is easier to scan feeders, woodland edges, and open fields without feeling overly zoomed in. At higher magnification, the image scale becomes more useful for confirming the target and placing a shot more precisely. The 1280x720 Micro-HD display supports that by presenting the thermal image with enough clarity for reticle use and menu navigation, while the multi reticle system gives the shooter a choice of aiming layouts to match different rifles or shooting preferences.

This model also brings the practical digital functions expected from a Smart HD thermal sight. Image capture and video recording at 1280x960 @ 60 fps allow clear documentation of hunts and follow-up review, while WiFi connectivity adds wireless streaming and control options. The aluminium housing, 90.00 mm eye relief, waterproof and fogproof construction, and 18.00 h battery life make it suitable for field use on rifles that may stay out for long sessions in changing weather.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and has focused on electro-optics for low-light and no-light use since its early years. The company is a United States manufacturer headquartered in Doral, Florida, and its core product areas include night-vision, thermal-imaging, and digital day-and-night optics. That background is directly relevant to products such as the Mars 4, which combine thermal sensing with onboard digital processing and recording functions.

ATN’s catalog covers traditional image-intensifier night vision as well as digital systems, and the company has been active in developing Smart HD optics for both observation and weapon-mounted use. It introduced the X-Sight II HD digital day-and-night sight series in 2015 and later expanded its digital platform with Obsidian 4 products in 2018. This emphasis on digital integration explains why ATN thermal riflescopes typically combine imaging, reticle management, recording, and wireless features in a single housing.
