What ‘s Laser Distance Meter?

The Laser Distance Meter also called Laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. 

When the Laser rangefinder is working, it shoots a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time of the laser beam from transmission to reception, and calculates the distance from the observer to the target. The Laser rangefinder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one-fifth to one hundredth of that of other optical Distance measuring equipment.
