8x42 Laser Rangefinding Binoculars

The Crosman RFB842 combines 8x magnification with a built-in laser rangefinder for distances from 5 to 1500 yards. It suits hunters and outdoor observers who need both clear optics and instant distance data in one unit.

Measurement Limits

The Class 3R laser operates below 0.5 mW and delivers accuracy within one yard. Ranging performance depends on target reflectivity, atmospheric conditions and the operator's ability to hold the unit steady at long distance.

8x Magnification with 42 mm Objectives

The fixed 8x power and 42 mm objective lenses set the exit pupil, field of view and low-light brightness. Buyers who need higher magnification, a wider field or a smaller form factor should choose a different configuration.
