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 under 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 interfere with 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 recommended to measure distant targets.
Mode selection
By pressing the Mode button (5, Fig.1), you can sequentially scan the Modes. The Mode under selection is indicated on the Display by flashing of the selectable feature. The "flashing" feature can be selected by pressing the Action button (6, Fig.1). The System operates in the setting Modes that are displayed as follows (refer to Fig.3):
Y/M: units of measurement: yards or meters (3, Fig.3).
