The Maven RFZ.1 combines the functions of a precision laser rangefinder and a variable-power monocular in one compact unit.
Unlike a conventional fixed-power rangefinder, the RFZ.1 features genuine 6–12× optical zoom. Use 6× for scanning terrain and locating targets, then increase the magnification to inspect details or obtain a more precise aiming point at longer distances.
The laser system measures from 5yd to a maximum of 4,500yd on highly reflective targets. Line-of-sight and angle-compensated modes allow the user to select the most suitable distance reading for flat or steep terrain.
Field and Forest modes help manage difficult ranging situations. Field Mode is intended for smaller targets against open backgrounds, while Forest Mode helps when ranging through vegetation, branches or poor weather.
Five selectable reticles and five display-brightness settings allow the display to be adjusted for different targets and lighting conditions.
