The Athlon Cronus ATS Pro Thermal Clip-On 35CL-640 transforms your existing riflescope into a thermal imaging system capable of detecting heat signatures in complete darkness. This clip-on thermal attachment mounts directly to most day-optic scopes, letting you preserve your current setup while adding next-generation thermal capability without swapping gear in the field. Whether you're hunting at night, conducting security patrols, or glassing unfamiliar terrain after sunset, a thermal clip-on bridges the gap between daylight and low-light hunting—and the Cronus ATS Pro does it without the bulk or cost of replacing your entire optic stack.

The user interface prioritizes speed and simplicity. Field adjustments happen quickly, so you can dial in your thermal image and get back to the task at hand. Multiple color palettes let you choose the thermal display that works best for your eyes and your environment—a feature that matters when you're scanning glass at dusk or navigating thick brush in complete darkness. The system also records video, so documentation, training, or post-hunt review becomes straightforward.

Mounting is flexible: use the included Picatinny rail adapter to attach the Cronus ATS Pro to your rifle's accessory rail, or pair it with an optional clip-on mount (sold separately) to attach it directly to your existing daytime scope. This modularity means the thermal upgrade works with whatever riflescope you already trust, not the other way around.
