Feature 1Normal laser range finder is used to measure distance and can't make scale marking, but this product can solve this problem to make marking simple. 2Comes with a professional tape measure of 19mm width and 5 meters length. And the error is less than or equal to 1.5mm, meeting the European MID secondary standard. 3Micro-motion locking design: The tape is automatically locked after being pulled out. Press the unlock button and the tape will rebound, avoiding scratching the finger. 4Magnetic ruler hook design: Can be adsorbed on metal materials to measure length. Adsorption force reaches up to 1.5 kg. 5Ruler hook compensation design: Measurement method 1: Take the inside of the ruler hook as the base point of 0 scale; Measurement method 2: Take the outside of the ruler hook as the base point of 0 scale.
