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.
Leica’s 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.
