Leica Calonox 2 View LRF

We have tested the Leica Calonox 2 View LRF clip-on device. The equipment is in like-new condition and comes with a Rusan Modular adapter of 62mm. This adapter allows you to attach the device directly to a scope with an outer diameter of 62mm. Additionally, the package includes a Rusan 22.5x viewing eyepiece with a modular fitting.

The Leica Calonox 2 Sight LRF is a top-of-the-line clip-on thermal sight that merges Leica’s optical expertise with advanced thermal imaging technology. Manufactured in Portugal, this device is compact, ergonomic, and easy to use. Its fully integrated laser rangefinder (LRF) enables precise distance measurements directly from the device or via a separate remote control.

The high-resolution thermal image remains sharp even in darkness, fog, and other challenging conditions. Featuring a high-quality European LYNRED sensor and Leica Image Optimization (LIO®) image processing, it delivers a contrast-rich and detailed image that aids in identifying targets.

The device is ready to use without the need for separate calibration, easy to install and transfer between riflescopes, and compatible with many rifle scopes. It is designed for hunters and nature observers who demand accuracy, durability, and reliable performance in all conditions.
