Stop guessing distance in the dark. The Athlon Optics Cronus ATS 35ML-400 pairs a high-resolution 12μm thermal sensor with a built-in 1,100-yard laser rangefinder, giving you both detection and precise ranging in a single handheld. Detect a heat signature at up to 3,000 yards and range targets out to 1,100 yards quickly: no secondary device.

Key Features
- Built-In 1,100-Yard Laser Rangefinder – The defining upgrade over the standard 35M model. Get accurate distance readings to your target without carrying a separate rangefinder. Supports single-shot and continuous ranging modes.
- Cutting-Edge 12μm Thermal Sensor – The 400 x 300 resolution sensor with ≤50mK NETD gives a clear thermal picture in complete darkness.
- Sharp OLED Display – The 640 x 400 high-resolution OLED delivers vivid contrast and crisp imaging. Five customizable color palettes let you dial in visibility for your specific environment.

- Hot Spot Tracking – Automatically detects and follows the hottest object in your field of view.
- 2.6x–10.4x Zoom Range – Start at the 2.6x base magnification with a 7.5° x 5.6° field of view, then zoom in to 10.4x. Picture-in-picture mode is also available.
- 9+ Hour Battery Life – The included 18650 battery and spare keep you running, and USB-C external power support means you can plug into a battery pack for continuous operation.
- WiFi & Athlon Thermal App – Record video, capture snapshots, and stream live footage directly to your iOS or Android device through the Athlon Thermal app. Review hunts or document surveillance observations.

- Weatherproof and Durable – IP66 waterproof, fog-proof, and shockproof construction handles rain and dust. At 14.8 oz, it adds only 2.5 oz over the non-LRF model.
Who It’s For
- Night hunters who range what they find. In the dark, the integrated LRF gives an accurate distance to predators without juggling a separate rangefinder.
- Long-range varmint hunters who work open terrain: continuous ranging mode tracks distance as targets move, without repeated button presses.
- Security professionals conducting nighttime operations who need both thermal detection and precise distance data in a single package.
The 35mm Cronus ATS monocular comes in two versions. The 35M-400 includes a visible laser pointer for target indication and weighs 12.3 oz. The 35ML-400 replaces the laser pointer with a 1,100-yard laser rangefinder and weighs 14.8 oz. If you need precise distance data, the 35ML is the clear choice. If you primarily scan and spot without ranging, the 35M is the lighter choice.
