Distance Meters, also known as “Electronic Tape Measures”, “Laser Distance Measuring Tools”, “Laser Range Meter”, “Laser Tape”, “Laser Distance Finders”, “Laser Measurer”, “Laser Measuring Tape”, “Electronic Distance Meter” or “Digital Measuring Devices”, offer true laser light (not sound) for the most accurate measuring. You simply point the laser distance measuring devices dot at a target like a wall, a house, a utility pole, nearly any object, and the device will show the distance on its LCD screen. These measuring devices will show multiple units of measure, you simply cycle through the units till you get to the units of measure you want to measure in, and then start taking measurements. You can even cycle through the units of measure after taking a measurement. These devices can also be put up against a wall and they measure from the back of the unit so that you get true wall-to-wall distance measurement. Same goes with ceiling measurements, lay the device on the backside, point it up and it will measure from the floor to the ceiling. These measuring devices are true time savers and are very accurate.
