Leica Calonox 2 Sight

The Leica Calonox 2 Sight is a next-generation thermal imaging clip-on designed for precision, performance, and seamless integration with your daytime optics. With a cutting-edge VOx sensor (640×480, 12 µm pixel pitch) and an ultra-sharp OLED display (1920×1080), it delivers brilliantly detailed thermal imagery, even in total darkness or adverse environmental conditions.

This clip-on solution mounts effortlessly in front of your daytime riflescope, providing 1× optical magnification and retaining the scope’s original zero—no need to re-zero. Its wide 10.3° × 7.7° field of view covers approximately 18 m × 13.5 m at 100 m, making it ideal for scanning open terrain or following heat signatures at extended distances.

About the Calonox 2 Series

The Leica Calonox 2 Series builds on the success of the original Calonox lineup with significant upgrades in image quality, usability, and digital functionality. Compared to the earlier models, Calonox 2 introduces a sharper Full HD OLED display (1920×1080), a faster 60 Hz refresh rate, and an upgraded VOx sensor (640×480 vs. 384×288) with 12 µm pixel pitch for enhanced thermal resolution and contrast.

Connectivity and user experience are also improved: the Calonox 2 includes built-in Wi-Fi + Bluetooth® for wireless control and live image sharing, as well as an expanded 32 GB internal memory for image and video recording. It also features faster charging options and IP67-certified weather sealing. These enhancements make the Calonox 2 Series more powerful, more connected, and more versatile for outdoor observation than ever before.
