The Athlon Optics Cronus ATS Pro 35-400 delivers the full Pro-grade thermal experience — ≤25mK sensor sensitivity, 1440p OLED display, ballistic calculator, and auto-shot recording — without the integrated laser rangefinder, making it the most direct path to top-tier thermal imaging for hunters who already carry a standalone rangefinder or simply don't need one built into the scope. Every core capability that defines the ATS Pro line is here: the same sensor, the same display, and the same feature set as the LRF-equipped 35L-400, at a lower weight and price point.

Key Features

• ≤25mK NETD Thermal Sensor – The 400 x 300 resolution sensor with 12μm pixel pitch delivers twice the thermal sensitivity of the ≤50mK sensors found in most competitors at this price point. That means clearer separation between targets and backgrounds, even in challenging conditions where temperature differentials are minimal — critical for picking out bedded animals or targets partially concealed by vegetation.

• 1440p OLED Display at 50Hz – The 0.49" OLED display with 1440 x 1080 resolution produces a noticeably sharper sight picture than the 1024 x 768 displays common in this class. The 50Hz refresh rate keeps fast-moving targets smooth and fluid, eliminating the stutter that makes shot timing difficult with slower displays.

• 35mm F1.0 Lens with 7.8° x 5.9° FOV – The fast F1.0 germanium lens maximizes infrared energy reaching the sensor, while the 7.8° x 5.9° field of view provides solid scanning coverage for tracking targets across open terrain or working tree lines.

• 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.

• Ballistic Calculator with Auto Holdover – Input your caliber, bullet weight, and muzzle velocity, and the integrated ballistic engine calculates holdovers in real time. Feed it distance data from your standalone rangefinder or use the built-in stadiametric ranging system, and the holdover point appears directly on the reticle — no mental math, no dialing turrets.

• Stadiametric Ranging – The built-in reticle-based ranging system lets you estimate target distance without any external device, providing a self-contained ranging solution when a dedicated rangefinder isn't available.

• 10 Reticles + One-Shot Zero + 10 Zeroing Profiles – 5 MOA and 5 MIL reticle patterns in 6 colors. One-Shot Zero for fast sight-in. Save up to 10 profiles (A–J) for different rifles, loads, or distances.

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

• Auto-Shot Recording + 128GB Storage – Recoil-activated recording captures before and after every shot automatically. 128GB built-in — no cards to manage.

• 10+ Hour Battery + WiFi/Bluetooth/HDMI – Dual-power system (1 built-in + 2 external batteries), USB-C backup, eco and standby modes. Stream live to the Athlon Thermal app or output via Micro HDMI.

• IP67 Weatherproof, -22°F to 122°F – Fully sealed, fog-proof, shockproof. Handles high-caliber recoil and temperature extremes without hesitation.

Who It's For

• Hunters who already carry a standalone rangefinder and don't want to pay for a second one built into the scope. The ATS Pro 35-400 gives you the identical sensor, display, and ballistic calculator as the LRF-equipped 35L-400 at a lighter weight (37.4 oz vs 41.3 oz) and lower price.

• Night predator and varmint hunters who prioritize thermal image quality and ballistic capability over integrated ranging. The ≤25mK sensor and 50Hz display deliver the same razor-sharp thermal picture as the rest of the Pro line.

• Multi-rifle hunters who switch between platforms. Ten zeroing profiles with One-Shot Zero let you move the scope between rifles or swap loads without re-zeroing from scratch every time.

• Hunters and tactical operators in extreme environments who need gear that won't fail. IP67 waterproofing, -22°F cold tolerance, and 10+ hours of battery life mean this scope keeps working when conditions push other optics past their limits.
