When you need to measure quickly and accurately, nothing matches the precision and speed of a laser measuring device. Laser rangefinders are also used as an alternative to a tape measure. To measure a large object like a room with a tape measure, one would need two people and a straight run with no obstructions to stretch the tape. With a laser measuring tool, the job can be completed by one operator with just a line of sight. 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.
