Laser distance meter

— instruments for measuring distances using a laser beam. The advantage of this method is, first of all, the ability to determine distances to inaccessible objects — located at a height, behind obstacles, etc. — it is enough that this object is within the range of the device (which can reach several tens of metres). At the same time, the measurement accuracy is quite high, they are carried out automatically and in a matter of seconds, and the design may include a built-in calculator to determine the area, volume and other parameters based on the measurement results. In addition, the use of a laser range finder eliminates the need to travel the measured distance and significantly saves time over large areas.
