Descriptions:HIGH ACCURACY: With laser precision technology, measurement accuracy up to 2mm, measuring distance extends to 80M; Switchable among M/In/Ft for free adjustmentDURABLE AND HANDY: IP54 waterproof level and dust-proof function protect the laser distance measure to the maximum extent; Pocket size laser measure with a aluminum alloy body looks more high-end and easy to store.MULTIPLE MEASUREMENT FEATURES : Area, distance, length, volume, continuous measurement, Pythagorean method-three points; Addition and subtraction; Low battery indication; 20 groups data memory; Manually delete data; Auto shut down after 150s without any operation to save powerSIMPLE OPERATION: Compared with manual measurement, the Laser Measure greatly reduces the measuring errors. In addition, it comes with electronic angle sensor to provide much preciser and more intuitive data. Assures you a easy and quick measurement.LCD BACKLIGHT AND MUTE SETTING : Large backlight screen provides you with a better visibility in dark areas; Mute setting allows you turn on or off the measure beep at your will, suitable for using in library, classroom and other quite placesELECTRONIC LEVEL FUNCTION: electronic angle sensor,real-time angle display, When the angle of the rangefinder changes, the angle change can be displayed on the screen in real time.
