Factors affecting measuring distance
Though maximum measurement distance depends on target reflectivity, weather conditions and other conditions, for most targets the unit will provide accurate ranging for up to 2,500 meters. Under good conditions a large size target can be measured up to 3,000 meters.
Target reflectivity depends on its color, surface finish, size, shape, position in relation to the laser beam, etc. Bright target colors are more reflective than darks. A polished surface is more reflective than a rough one. Larger targets reflect better than small ones. Ranging a target perpendicular to the laser beam provides better results than the one positioned at a sharp angle to the beam.
Weather conditions that influence air transparency (rain, fog, snow, mist) reduce maximum range. Bright sunny days will reduce performance as well as IR sun radiation may cover reflected laser impulses.
While the unit will measure through many glass types, measuring through glass may reduce accuracy.
Natural hand tremor decreases the accuracy of long distance ranging. Using of a tripod is highly recommended.
Note: device may produce false readings when reticle is aimed at the sun or in ± 20˚ solid angle from the sun.
Target selection logic
On its way towards the target laser beam may reflect from various objects, thus decreasing ranging accuracy. The
