The high-resolution 400×300 sensor paired with a 1200×900 OLED display ensures that even in fog, rain, or dense brush, you’ll identify targets with razor-sharp clarity.

Not all environments are the same, and neither is your hunt. The Cronus ATS 35C-400 features 7 customizable color palettes, allowing you to adapt your view for different terrains and lighting conditions. Whether you prefer White Hot for crisp contrast, Red Hot for high-heat tracking, or Sepia for reduced eye strain, you can fine-tune the display for maximum visibility and comfort. Adjustable brightness and contrast settings ensure the image is always optimized for your specific environment.

For long-range hunters, precision goes beyond visibility. The Cronus ATS 35C-400 integrates seamlessly with Athlon’s Ballistics App, giving you accurate ballistic data for preset distances. Whether you’re hunting at extended ranges or adjusting for different loads, this feature ensures that every shot is calculated for maximum accuracy.

Reliability isn’t optional in the field. With an IP68-rated waterproof and shockproof build, the Cronus ATS 35C-400 is engineered to handle harsh environments and rugged hunts. A long-lasting 10+ hour battery life, Eco-Mode, and Standby Mode keep you in action longer, reducing unnecessary power drain while ensuring your thermal is instantly ready when needed. The 10 illumination settings allow you to fine-tune brightness for any environment, ensuring perfect visibility whether you’re in open fields or dense brush.

Capture the moment, review your shots, and share your success. The built-in WiFi video recording and 32GB memorylet you document every hunt without extra gear. With Auto-Shot Recording, the scope automatically saves footage before and after you take a shot, so you never miss a critical moment. Whether you're after hogs, coyotes, or other nocturnal predators, the Cronus ATS 35C-400 is the ultimate upgrade for hunters who demand top-tier performance, accuracy, and reliability in any condition.
