Adding a thermal scope to a hunting rifle usually means bolting on a heavy, ring-mounted unit that changes the balance of the gun and takes minutes to swap between platforms. The Cronus ATS Pro 25P-250 is the lightest thermal scope in the Cronus ATS Pro lineup — 17.8 ounces with a Picatinny mount that slides directly onto any rail without scope rings, so you can move it between rifles in seconds without re-zeroing. Same ballistic calculator, smart video recording, and One-Shot Zero as the full-size models, in a package that won't make your rifle feel front-heavy.

Key Features

• 256 x 192 Thermal Sensor with ≤30mK NETD – The 12μm pixel pitch sensor delivers clean thermal imaging with ≤30mK sensitivity — enough to pick out heat signatures in fog, rain, and low-contrast conditions where standard optics fail. The 256 x 192 resolution provides clear target identification at typical predator and varmint engagement distances.

• Compact Picatinny Mount Design – At 8.8" long and 17.8 oz, the 25P-250 is the smallest and lightest scope in the entire Cronus ATS Pro family. The integrated Picatinny mount eliminates scope rings entirely — slide it on, lock it down, and you're hunting. Moving it between rifles takes seconds.

• 25mm F1.0 Lens with 7.0° x 5.3° FOV – The fast F1.0 germanium lens maximizes infrared energy reaching the sensor. The 7.0° x 5.3° field of view provides scanning coverage well suited to typical nighttime engagement distances.

• 3.6x–14.4x Zoom Range – Start at 3.6x base magnification for scanning, then push to 14.4x for target identification at distance.

• 1024 x 768 OLED Display at 50Hz – The 0.39" OLED delivers a crisp, high-contrast sight picture. The 50Hz refresh rate keeps moving targets smooth and trackable.

• Ballistic Calculator with Auto Holdover – Input your caliber, bullet weight, and muzzle velocity, and the integrated ballistic engine calculates holdovers in real time. The holdover point displays directly on the reticle — no mental math, no dialing turrets.

• 10 Reticles + One-Shot Zero – 5 MOA and 5 MIL reticle patterns in 6 colors. One-Shot Zero for fast sight-in — fire a single round, mark the point of impact, and the scope calculates the correction automatically.

• 7 Color Palettes – White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, and Sepia.

• Smart Video Recording + 32GB Storage – Recoil-activated recording captures before and after every shot automatically. 32GB built-in storage holds hours of footage without external cards.

• 9+ Hour Battery + WiFi – Dual-power system (1 built-in + 2 external 18500 batteries), USB-C backup, and standby mode. Stream live to the Athlon Thermal app via WiFi.

• IP67 Weatherproof, -4°F to 122°F – Fully sealed, fog-proof, shockproof. Handles high-caliber recoil and harsh conditions.

Who It's For

• Hunters who want Pro-grade thermal capability at the lowest weight and cost in the lineup. The 25P-250 delivers a ballistic calculator, smart video recording, and One-Shot Zero at under 18 ounces — features that aren't available on most thermal scopes at any weight.

• AR-platform and lightweight rifle builders who need a thermal scope that integrates directly onto a Picatinny rail without adapters or scope rings, adding minimal weight to the platform.

• Night predator and varmint hunters working at typical engagement distances. The 1,400-yard detection range and ≤30mK sensitivity cover the distances where most coyote, hog, and varmint shots happen.

• Hunters adding their first thermal scope who want a capable, full-featured optic without the investment of a 400x300 or 640x480 platform. The 25P-250 is the entry point to the ATS Pro ecosystem.
