Category: Tag:

leica calonox sight 50500 Thermal imaging camera is ideal for use with a riflescope and is therefore equipped with 1x magnification. Thanks to its one-piece construction, the Calonox Sight offers outstanding reliability and a consistently precise, repeatable point of impact.

Superior image quality with Leica Image Optimization (LIO™)

Uniquely sharp, detailed, high-contrast images.

With the Calonox thermal cameras, Leica continues its long, successful track record in digital image optimization, and extends its excellent reputation as a camera manufacturer. Leica’s own image processing (Leica Image Optimization – LIO™) improves the image with special algorithms, thus achieving particularly detailed color gradations, excellent contrast, and high detail resolution.

The outstanding recognition range of the Leica Calonox Sight is based on a high-end vanadium oxide (VOx) sensor with 384 x 288 pixels and 17 µm pixel size with excellent temperature resolution.

Dual use: clip-on and thermal camera

The choice is yours.

It’s your call: The Leica Calonox Sight can either be used for observation as a thermal camera, or connected to your riflescope using an adapter mount. In either case, no details will remain hidden, even at great distances.

Impressive detail recognition at a long range

Detect, recognize, identify.

See more, identify game safely: With a defined target size of 1.7 x 0.5 m, the Leica Calonox Sight can detect targets up to a distance of 2,000 meters, recognize targets up to 700 m, and precisely identify them up to 350 m.

Extra-large field of view

Keep an eye on everything.

Ideal for close-up observations, the 42-mm objective provides a large field of view, and optimum overview at a long range. Equipped with 1x magnification, the Leica Calonox Sight is specially optimized for use with a riflescope.

Adapter rings & zeroing in

Simply be sure.

To make full use of the Leica Calonox Sight as an attachment, you need adapter rings that match your riflescope.

With clip-on mode, you can adjust the screen section for use with your riflescope. To enable successful zeroing in, the reticle correction helps precisely align the screen with the reticle in the riflescope. The Calonox Sight App remote function supports you in this.

Calonox Sight App

Convenient remote control via smartphone.

The Calonox Sight App offers even more support by letting you conveniently control functions via smartphone. Connecting your device via Bluetooth, you can change menu settings quickly and easily using your cell phone. With a simple click, you can switch the display from day mode to night mode.

Elegant design & intuitive operation

Reduced to the essentials.

The shapely product design in the well-known Leica style is geared towards the user’s hunting needs. Its cylindrical shape and easy operability integrate perfectly into the hunter’s equipment – whether mounted or hand-held. The user-friendly, intuitive three-button menu offers streamlined navigation, which enables easy and quick handling even when wearing gloves.

OLED display & rechargeable battery

State-of-the-art technology.

The powerful OLED display with 1024 x 768 pixels enables comfortable observation and reliable identification when stalking or when shooting from blinds. The permanently installed rechargeable battery with approx. 11 hours of power is particularly well protected against cold and moisture. And charging is possible during operation, e.g. by using a powerbank.
