When the night takes over, this scope sees what others can’t. With a 640x480 thermal sensor and an industry-leading ≤20mK NETD rating, the Cronus ATS Pro 50L-640 detects even the slightest heat signatures, ensuring crisp, high-contrast visuals in fog, rain, or high-humidity conditions. No more struggling to differentiate brush from a moving target—every heat source stands out clearly, even in the worst conditions.

Forget the hassle of carrying an external rangefinder—the built-in LRF instantly measures distances up to 1,600 yards with ±1-yard accuracy. Paired with the integrated ballistic calculator, you’ll get real-time holdover adjustments, ensuring every shot is backed by data for pinpoint accuracy at any range. Whether you're hunting coyotes at 500 yards or taking down a hog at close range, this scope delivers.

Field of view matters—especially when scanning for multiple targets.

Whether you're waiting in a tree stand or moving through rugged terrain, your scope stays ready when you are.

Tracking fast-moving targets? The 50Hz refresh rate ensures smooth, real-time motion, so targets appear naturally, not choppy or delayed. Plus, with 10 built-in reticle options (MOA & MIL) and 6 reticle color choices, you can customize your sight picture for quick target acquisition or long-range precision.

Capturing your best shots has never been easier. The Auto-Shot Recording feature detects recoil and automatically records before and after your shot, so you can review, analyze, and share every key moment. With WiFi connectivity and 128GB of built-in storage, you can store hundreds of hours of footage without worrying about memory cards.

Durability is non-negotiable.
