AR891 80 meters Laser rangefinder product features is the use of laser for laser range finder for accurate determination of the distance of the target device. Laser rangefinder to the target injection in the laser working very fine bouquet, the object reflector is received by the photoelectric element of the laser rangefinder laser beam manufacturers, the laser beam is measured by the timer time from the transmitter to the receiver, to calculate from the observer distance to the target. Laser rangefinder light weight, small size, simple operation fast and accurate laser rangefinder price, the error is only one fifth to one percent of the number of other optical rangefinder, which is widely used in topographic survey , battlefield measure, tank rangefinder models, aircraft, ships and artillery on targets ranging rangefinder to measure cloud height, etc. aircraft, missiles and satellites. It is to improve the high-tanks, aircraft, warships and artillery accuracy of important technical equipment.
