Brief description; introductionThis professional rangefinder uses laser technology to accurately, quickly and easily measure distance, area and volume. It has a wide measurement range of 0.05 to 40m (131ft), especially a high accuracy of 2mm. In addition, when direct measurement is not feasible, the meter can use the Pythagorean theorem to indirectly measure distance or length. The meter also has a variety of functions, including continuous measurement, plus/minus function and maximum/minimum measurement. Other main features include 100 data memories, switchable units (meters, inches, and feet), and a backlit LCD with multi-line display. The bubble level provided can be used as a level tool. Laser rangefinders are widely used in construction and industry. Especially in large areas such as rooms, apartments, buildings, real estate, factories, warehouses, gardens, roads, infrastructure, etc., accurate measurement of distance, area and volume is very useful and convenient.
