Leica Rangemasters have been an essential aide for field sportsmen for many years now. They combine high-quality optics with durable mechanics and complex electronics in an extremely compact design. Like all other Leica rangefinders, they always meet precise parameter determination standards anytime and anywhere. This way, they support every hunter and provide answers to of his essential questions. In a record-breaking time of 0.3 seconds, Rangemasters determine all the important parameters with maximum precision and ensure the necessary safety for accurate shots. Thanks to their compact form, they fit easily into any pocket. The Leica Rangemaster CRF 2800.COM offers limitless freedom and precision. With the Leica Hunting app, individual ballistics settings can be configured conveniently on the smartphone. Leicas own ABC ballistics program calculates the individual ballistic output values based on caliber, bullet type, trajectory and weight. The CRF 2800.COM calculates the exact ballistic distance and holdover correction, adjusting for temperature, air pressure and angle. Within mere fractions of a second, either the linear, equivalent horizontal range (EHR), the holdover, or the number of clicks are calculated and displayed.
