Leica Calonox 2 Sight

The Leica Calonox 2 Sight thermal sight 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 and practical, intuitive operation – it’s very easy, for example, to select day or night mode. 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 no longer needs individual calibration, but can be used out-of-the-box and swapped between rifles.

Lecia Calonox 2 Sight LRF Features

Focusing on the essentials

The Leica Calonox 2 Sight thermal sighting camera is a genuine benchmark in terms of design and function. Designed and made in Germany, the Leica Calonox 2 Sight focuses on safe and ethical hunting with its ergonomic compact shape, practical and intuitive control buttons, and optical performance.

Large field of view and very detailed image

Hunters and nature observers can count on natural, sharp, high-contrast images, thanks to the high-quality LYNRED sensor and the processing software that’s been further refined by Leica (LIO™ – Leica Image Optimization). Together with a large field of view, objects with the standard size of 66.9 in (1.7 meters) can be clearly found at up to 2417 yrd (2210 meters).  Recognition is possible at 842 yrd (770 meters) and reliable identification at 427 yrd (390 meters).

Easy to swap between different rifles

Thanks to highest-precision components and a sophisticated manufacturing process, the Leica Calonox 2 Sight arrives precisely centered. As a result, the clip-on camera no longer needs individual calibration, but can be used out-of-the-box and swapped between rifles. Point of impact does not change, even if the device is repeatedly removed and remounted.

Light & compact unit with the right riflescope

The Calonox 2 Sight can be used with most commercially-available riflescopes. Combining it with the Leica Amplus 6 3-18x44i L-4w BDC (MoA) creates a perfect unit: a compact overall system for night hunting. Mounting is done via standard adapters, which are available for almost all scopes.

Optional remote control for activating video and photo function

An optional remote control can be conveniently attached to the comb or forestock and activates the photo/video function. This eliminates the need to change position and allows continuous sighting through the scope.

Software-based shutter is silent and smooth

Conventional thermal cameras periodically recalibrate themselves with an audible “click” and a frozen frame. The Leica Calonox 2 thermal cameras are designed to be “shutterless”. Leica software enables silent and instantaneous recalibration – without freezing the image.

Easy to switch from day to night mode

Like all Leica products, the Leica Calonox 2 Sight can be operated intuitively. A large, sturdy metal control ring turns the device on – and makes it easy to switch from day to night mode. A latching magnetic switch keeps the unit powered up during a switchover, thus saving time.
