It mounts directly to any Picatinny rail no scope rings, no tube diameter compatibility questions making it the fastest thermal scope in the Cronus lineup to move between rifles or set up on a new platform.

The Athlon Optics Cronus ATS Pro 35P-400 is a compact, Picatinny-mounted thermal scope that puts the same ≤25mK sensor and 35mm F1.0 lens from the full-size ATS Pro line into a package that weighs under 20 ounces and measures just 9.6 inches long. It mounts directly to any Picatinny rail — no scope rings, no tube-diameter compatibility questions — making it the fastest thermal scope in the Cronus lineup to move between rifles or set up on a new platform.

Athlon Cronus ATS Pro thermal sensor NETD sensitivity rating comparison

Key Features
  • ≤25mK NETD Thermal Sensor – The 400 x 300 resolution sensor with 12μm pixel pitch delivers the same thermal sensitivity as the full-size ATS Pro scopes — twice the sensitivity of the ≤50mK sensors found in most competitors. You get clean target-to-background separation even in challenging conditions where temperature differentials are minimal.
  • Compact Picatinny Mount Design – At 9.6" long and 19.7 oz, the 35P-400 is roughly half the weight and two-thirds the length of the tube-mounted ATS Pro scopes. The integrated Picatinny mount eliminates scope rings entirely — slide it onto the rail, lock it down, and you're ready to hunt. Moving it between rifles takes seconds.
  • 35mm F1.0 Lens with 7.9° x 5.9° FOV – The fast F1.0 germanium lens maximizes infrared energy reaching the sensor. The 7.9° x 5.9° field of view provides solid scanning coverage for tracking targets across terrain.
  • 3.3x–13.2x Zoom Range – Start at 3.3x base magnification for wide-area scanning, then push to 13.2x for positive identification at distance.
  • 1024 x 768 OLED Display at 50Hz – The 0.39" OLED produces a crisp, high-contrast thermal image with 50Hz refresh for smooth tracking of moving targets.
  • 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.

Seven thermal color palette options on the Athlon Cronus ATS Pro
  • 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 move thermal optics between multiple rifles. The Picatinny mount eliminates scope rings and tube-diameter concerns — slide it on, lock it down, and you're zeroed with One-Shot Zero in a single round. No other mounting system in the ATS Pro line is this fast to swap.
  • Weight-conscious hunters and tactical operators who need thermal capability without the bulk. At 19.7 oz, the 35P-400 adds less than half the weight of a full-size thermal scope to your rifle — a meaningful difference on extended carries and stalks.
  • Night predator and varmint hunters who want the same ≤25mK sensor sensitivity and ballistic calculator as the full-size Pro scopes in a more portable package. The 1,950-yard detection range covers the distances most predator and varmint engagements happen at.
  • AR-platform and tactical rifle shooters who already have Picatinny rails and want a thermal scope that integrates directly without adapters or aftermarket rings.
