Athlon Optics Cronus ATS Pro 35L-400 Thermal Scope with LRF

Athlon Optics Cronus ATS Pro 35L-400 Thermal Scope with LRFThe Athlon Optics Cronus ATS Pro 35L 400 is a complete thermal weapon system that combines 25mK sensor sensitivity, a 1440p OLED display, and an integrated laser rangefinder with ballistic calculator into a single optic eliminating the need for separate ranging and holdover devices. Where most thermal scopes in this price range force you to choose between sensor quality and features, the ATS Pro delivers both: razor sharp thermal imaging out to 2,620

The Athlon Optics Cronus ATS Pro 35L-400 is a complete thermal weapon system that combines ≤25mK sensor sensitivity, a 1440p OLED display, and an integrated laser rangefinder with ballistic calculator into a single optic — eliminating the need for separate ranging and holdover devices. Where most thermal scopes in this price range force you to choose between sensor quality and features, the ATS Pro delivers both: razor-sharp thermal imaging out to 2,620 yards with instant distance data and automatic shot solutions.

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.

• Built-In Laser Rangefinder (10–1,600 yds, ±1 yd) – Get precise distance measurements to your target without lifting your head from the scope or reaching for a separate device. One button press returns distance data that feeds directly into the ballistic calculator for an immediate shooting solution.

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

• 10 Built-In Reticles + One-Shot Zero – Choose from 5 MOA and 5 MIL reticle patterns in 6 colors to match your shooting discipline and preferences. One-Shot Zero gets you on target fast — fire a single round, mark the point of impact, and the scope calculates the correction automatically. Save up to 10 zeroing 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 give you full flexibility to optimize contrast for any environment. Green Hot excels in wooded terrain, while White Hot provides the sharpest silhouettes in open fields.

• Auto-Shot Recording + 128GB Storage – Recoil-activated recording captures footage before and after every shot automatically. With 128GB of built-in storage — no memory cards to lose or forget — you can log hundreds of hunts for review, training, or sharing.

• 10+ Hour Battery Life with Dual-Power System – One built-in rechargeable battery plus two included external batteries keep you running through extended hunts. USB-C external power support lets you connect a battery pack for continuous operation from a blind or stand. Eco and standby modes stretch runtime even further.

• WiFi, Bluetooth & HDMI Output – Stream live thermal footage to your phone through the Athlon Thermal app for recording, snapshots, and remote control. Micro HDMI output connects to an external monitor for shared viewing during team operations or training.

• IP67 Weatherproof, -22°F to 122°F – Fully sealed against dust and submersion. Fog-proof and shockproof construction handles recoil from high-caliber rifles and performs in temperature extremes from frigid mountain hunts to blistering summer nights.

Who It’s For

• Night predator and varmint hunters who want ranging, ballistics, and thermal imaging in a single optic. The integrated LRF and ballistic calculator eliminate the fumble of switching between devices in the dark, giving you faster shot-to-shot cycles on coyotes, hogs, and other fast-moving targets.

• Serious shooters upgrading from entry-level thermal scopes. If you’ve outgrown a 384-resolution sensor or a scope without rangefinding, the ATS Pro’s ≤25mK sensitivity, 1440p display, and 50Hz refresh represent a generational improvement in image clarity and capability.

• 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.
