The above data represents typical values. Test conditions: flat target, target size greater than laser beam diameter, atmospheric visibility of 23 kilometers, laser perpendicular incidence. Additional note: The range is shorter on sunny days than on cloudy days; if a laser beam hits more than one target, the laser pulse energy is dispersed, which may shorten the measurable distance; the measuring range is capped at 500 meters.
