The Leica Calonox 2 Thermal Clip On is not just a further development - it's a genuine benchmark in terms of design and function. Completely designed and made in Germany, it wins users over with its compact ergonomic shape, practical, intuitive buttons, and the world's first fully-integrated laser rangefinder (LRF), which can be activated very easily - either on the device, or via optional remote control. The high-quality European sensor from LYNRED, together with Leica's proven image processing software (Leica Image Optimization - LIO) ensures even sharper images, rich in contrast and detail. What's more, the Calonox 2 Sight LRF no longer needs individual calibration, but can be used out-of-the-box and swapped between rifles.
