Laser Distance Measuring Tape 40M 60M Digital Tape Measure 2-in-1 Laser Meter Trena Range finder Construct Tool Measuring Tool 1. Two modes, more worry-free 2.5m tape measure distance is recommended for short distance use, 60m laser distance measurement is recommended for long distance use 3. The high-definition backlight digital display is accurate to millimeters, and the data observation is more intuitive, avoiding the errors that may be caused by the visual scale. 4. Laser continuous measurement and real-time refresh data, suitable for non-planar distance measurement, continuous scanning of real-time distance 5. Double photosensitive holes, the stability is significantly improved 6. The self-locking device is easy to use and does not hurt the hand. When it is pulled out, it will lock the current position in real time and pre the button to retract it. 7.
