Laser distance meters accurately measure long distances in straight lines by using the reflectivity of a laser beam to calculate distance. The LDM150 is a pro-grade tool measuring as far as 150ft with 1/16in accuracy throughout the range and is IP54 rated for use in dusty and rainy environments. This laser distance meter can measure length area volume continuous and 2-Point Pythagoras indirect measurements. LDMs measure where a tape measure can't. The LDM150 is useful for estimating paint or flooring measurements measuring the heights of walls and trusses calculating warehouse space taking indirect measurements and more.
