A distance meter is handheld tool that uses a laser to take distance measurements.
Laser greatly improve the accuracy of measurements, tolerant within one millimeter at distances up to 100 meters (330 feet). They also greatly improve the ease of taking measurements, with simple point and shoot operation. Measurements can be made as rapidly as needed with just one technician.
Distance meters often include a memory function that allows the operator to record measurements onto the device and recall the data later for analysis. Additional features can include compass functions, edge-sensing functions, and the ability to make quick calculations for area and volume.
