Leica Rangemaster CRF 2800.COM is the first Leica rangefinder with integrated Bluetooth. Together with the specially designed smartphone app, this offers limitless freedom and precision. Combining precise distance measurement, the Leica ABC ballistics system, intuitive operation, Bluetooth technology and a unique design, Leica sets new standards as a pioneer in rangefinding. With the Leica Hunting app, developed especially for the CRF 2800.COM, individual ballistics settings can be configured conveniently on the smartphone. The app makes it possible to select the appropriate calibration for the gun. Leicas own ABC ballistics program calculates the individual ballistic output values based on caliber, bullet type, trajectory and weight. This data is transmitted via Bluetooth to the CRF 2800.COM, which calculates the exact ballistic distance and holdover correction, adjusting for temperature, air pressure and angle.
