This meter is 3in1 design digital laser rangefinder, laser ranging, 5m tape measure, and laser cro-marking, all in one. It has various kinds of measurement functions including single/continuous measurement, area measurement, volumes measurement, and Pythagorean measurement. Equipped with historical data memory function, it can holds max 20 groups of data. Wide applications, suitable for road engineering, housing, construction engineering, water conservancy engineering, electric power engineering, pipeline engineering, etc..Features:1. 3in1 design digital laser rangefinder, laser ranging, 5m tape measure, and laser cro-marking, all in one.2. With high elasticity and toughne ABS+TPR housing, anti-slip and drop resistance, effective dust-proof, can provide lonf service time.3. LCD display with backlight, clear definition, you can see the measurement data clearly even in the dim-light environment.4. 5m coated manganese steel tape short-range measurement, with ruler hook for easy to use, and with both imperial scale and metric scale.5. With self-locking device, automatically lock the current measurement position after the tape is pulled out, pre the unlock button to automatically rebound the tape, more safer and will not hurt your hands anymore.6. The laser ranging meter(40m/60m optional) is designed for long-distance measurement, and with laser cro-marking function, which provides a nice reference of horizontal and vertical lines for the renovation project.7.
