context_page_description: A laser rangefinder is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used.
context_section_description: Laser rangefinders are also used in several industries like construction, renovation and real estate as an alternative to a tape measure, and was first introduced by Leica Geosystems in 1993 in France.  To measure a large object like a room with a tape measure, one would need another person to hold the tape at the far wall and a clear line straight across the room to stretch the tape.  With a laser measuring tool, the job can be completed by one operator with just a line of sight. Although the tape measure is typically more accurate, laser measuring tools can be calibrated to be generally reliable when taking several measurements. Laser measuring tools typically include the ability to produce some simple calculations, such as the area or volume of a room, as well as switch between imperial and metric units. These units can be found in hardware stores and online marketplaces.
