The 2281-20 and 2282-20 (pictured) Laser Distance Meters from Milwaukee Tool offer memory storage, an easy-to-read display, rugged over-molding, the ability to add/subtract distances and dimensions, and the ability to attach the unit to a tripod for the most accurate measurements. In addition, each unit is designed to fit squarely into corners and lay flat/level when on or against a flat surface for better accura-cy. Both feature 1/16” accuracy, an IP54 protection class and include the device, two AAA batteries, a carrying case and manual/quick reference guides.
