The new Leica Calonox 2 Sight LRF thermal sighting camera 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.
The essentials
- Entirely designed & made in Germany
- The only premium thermal sighting camera with fully-integrated rangefinding up to 1312 yrd (1200 meters)
- No additional rifle calibration needed (use “out of the box”)
- large field of view and very detailed image, optimum viewing comfort
- extremely easy operation with a few intelligent buttons
For the first time with integrated laser rangefinder
The new Leica Calonox 2 Sight LRF thermal sighting camera is a genuine benchmark in terms of design and function. Designed and made in Germany, the Leica Calonox 2 Sight LRF wins users over with the world’s first fully-integrated laser rangefinder (LRF) for up to 1200 meters – enabling safe and ethical hunting.
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 LRF 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.
*Deviations may occur for technical reasons. Please see operating instructions.
Light & compact unit with the right riflescope
The Calonox 2 Sight LRF can be used with most commercially-available riflescopes. Combining it with the Leica Fortis 6 1.8-12x42i creates a perfect unit: a compact overall system for night hunting. Mounting is done via standard adapters with M43x0.75 thread, which are available for almost all scopes.
Optional remote control for activating the laser rangefinder
The fully-integrated laser rangefinder (LRF) can be easily activated via optional remote control. This remote control can be conveniently attached to the comb or forestock and activates either the rangefinder or the photo/video function.
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 LRF 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.

Instructions for use
Please note the following information concerning the point of impact and regarding the liability of Leica Camera AG (“LEICA”).
The Calonox 2 Sight / Calonox 2 Sight LRF (hereinafter referred to as “Calonox”) is adjusted ex works such that the point of impact can shift by up to 2.4 cm at 100 m. In addition, the overall system used (e.g. rifle, mount, adapter, riflescope) may shift the point of impact, due to the quality of the riflescope and adapter used as well as the type of mount, a changed center of gravity, or additional weight on the riflescope lens.
The Calonox provides support for safe and responsible hunting. You yourself must always assess your surroundings, the surroundings of the target, and the area in between, as well as the current overall situation and its variability. You yourself are responsible for your shot. You are also responsible for ensuring that the overall system works perfectly in conjunction with the Calonox.
LEICA recommends that you familiarize yourself with the Calonox on a shooting range before using it to hunt. Also check the overall interplay of the equipment and make sure the point of impact is correct. Furthermore, LEICA recommends that you regularly compare all settings with real shots in a safe environment (e.g. shooting range) before using the device to hunt. Based on your own assessment of “whether” and “how”, adjust the settings as required. Users of the Calonox assume full personal responsibility for the use of all functions.
LEICA accepts no liability for damages arising in connection with the use of the Calonox, except as stated in the following sentences. This exclusion does not apply to damages caused by an intentional or grossly negligent breach of duty by LEICA or by a legal representative or vicarious agent of LEICA.In the event of a simple or slightly negligent breach of duty by LEICA or a legal representative or vicarious agent of LEICA, LEICA shall only be liable (a) – albeit without limitation – for damages resulting from injury to life, body, or health; and (b) for damages arising from the breach of material contractual obligations (material contractual obligations being those obligations whose fulfillment is essential for the proper execution of the contract and on whose compliance the customer regularly relies and is entitled to rely); in these cases, LEICA’s liability shall be limited to the level of compensation typical for the respective contract and foreseeable at the time of conclusion of the contract. The limitations of liability in the preceding sentence shall not apply if LEICA has fraudulently concealed a defect or has assumed a guarantee for the quality of the goods which entitles the user to compensation. In addition, any mandatory statutory liability, in particular under the Product Liability Act, shall always remain unaffected.
