This professional rangefinder uses laser technology to accurately, quickly and easily measure distance, area and volume. It has a wide measuring range of 100m (328ft) and a particularly 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 99 data memories, switchable units (meters, inches, and feet), and backlit LCD with multi-line display and IP54 splash-proof. 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. It can also be used for interior decoration design, supervision and on-site inspection.
