The BRESSER 4x21 Rangefinder 800 works in short distance and out to 800 meters. Its presicion laser
and optics can perform in adverse conditions, including fog and rain. When selecting a target for
measuring distance please note that it must be a target that the laser can send and recieve a signal
from (e.g. aiming at a barbed wire fence will not have good results because of the holes in the fence).
Choose a tree, rock, or other surface that is clearly visible for target selection.

To measure distance, press the On/Measure button again after powering on (fig. 4).

towards the front when powered on (fig.3).
