Description
Introducing the Leica Calonox 2 LRF Clip-On Thermal Sight. Representing a new generation of premium thermal imaging technology, combining exceptional optical performance with innovative engineering in a compact and rugged package. Manufactured in Leicas state-of-the-art facility in Portugal, this advanced thermal sighting camera has been designed to deliver outstanding reliability, precision, and ease of use for demanding field applications. Its ergonomic design, intelligent control layout, and robust construction ensure comfortable operation in challenging environments, while Leicas renowned attention to detail is evident throughout every aspect of the device.
One of the standout features of the Calonox 2 Sight LRF is its fully integrated laser rangefinder, making it the only premium thermal sighting camera in its class to offer seamless rangefinding capabilities up to 1,000 meters (1,094 yards). The laser rangefinder can be activated directly from the device or via an optional remote control, allowing users to obtain accurate distance measurements quickly and efficiently. Unlike many traditional thermal clip-on systems, the Calonox 2 Sight LRF requires no additional rifle calibration, enabling users to mount the device and begin operating immediately. This out-of-the-box functionality allows for convenient transfer between rifles without the need for repeated zeroing procedures. At the heart of the system is a high-performance 640 x 480 pixel VOx thermal sensor with a 12 m pixel pitch and an impressive thermal sensitivity of less than 40 mK NETD. Combined with Leicas proprietary Leica Image Optimization (LIO) software and a premium European-made LYNRED sensor, the device produces exceptionally sharp thermal images with outstanding contrast and detail. The 42 mm objective lens and 1x optical magnification provide a generous field of view of 10.3 x 7.7, equivalent to 18 x 13.5 meters at 100 meters, allowing users to effectively scan large areas while maintaining excellent target awareness. The system delivers a detection range of up to 2,210 meters, recognition range of 770 meters, and identification range of 390 meters, ensuring reliable performance across varying observation distances.
The viewing experience is further enhanced by a high-resolution OLED display featuring a resolution of 1280 x 960 pixels and a fast 60 Hz refresh rate. This combination ensures smooth image rendering and minimal latency, resulting in a clear and comfortable viewing experience even during prolonged use. The shutterless operation eliminates image interruptions commonly associated with traditional thermal devices, while the advanced image processing technology maintains consistent image quality in changing environmental conditions. Designed with connectivity and recording capabilities in mind, the Calonox 2 Sight LRF features integrated Wi-Fi and Bluetooth connectivity, along with a USB-C interface for data transfer and charging. Users can capture both photos and videos at a resolution of 640 x 480 pixels and store them directly on the devices generous 32 GB internal memory. These features make it easy to document observations, review footage, and share content when required. Wireless connectivity also enhances device management and expands operational flexibility in the field.
Built to withstand harsh operating conditions, the Calonox 2 Sight LRF features a durable housing constructed from glass-fiber reinforced plastic with additional silicone reinforcement. The device is nitrogen-filled and certified to the IP67 protection standard, providing excellent resistance against dust, moisture, and adverse weather conditions. It operates reliably in temperatures ranging from -20C to +50C and offers approximately five hours of battery life on a single charge. Weighing just 658 grams and measuring 139 x 110 x 61 mm, the thermal sight maintains a compact profile while remaining robust enough for professional use. With its combination of advanced thermal imaging performance, integrated laser rangefinding, premium European sensor technology, and effortless operation, the Leica Calonox 2 Sight LRF establishes a new benchmark in the thermal optics market. Its ability to deliver high-resolution thermal imagery, accurate distance measurement, and calibration-free deployment makes it an exceptionally versatile solution for users seeking reliability, precision, and convenience in a single, high-performance thermal sighting system.
