Leica Calonox 2 Sight LRF

The Leica Calonox 2 Sight LRF is the most advanced thermal clip-on in Leica’s lineup, combining outstanding thermal imaging performance with an integrated eye-safe laser rangefinder (905 nm) for precise distance measurement. Featuring a large VOx sensor (640×480, 12 µm pixel pitch) and a brilliant OLED display (1920×1080 resolution), it provides unmatched detail, contrast, and identification capabilities—day or night.

Designed to mount seamlessly in front of a daytime riflescope, the Calonox 2 Sight LRF maintains your original zero with 1× optical magnification. Its field of view of approximately 18 m × 13.5 m at 100 m, providing excellent spatial awareness while scanning or tracking in open terrain. Integrated Wi-Fi, Bluetooth®, and 32 GB of internal storage enable real-time sharing and onboard recording.

About the Calonox 2 Series
