Ultra Sonic Distance Measure, Color : Black

The ULTRASONIC DISTANCE METER + LASER POINTER is a perfect tool to quickly know the distance, area, and volume of a room! It can measure distances in a straight line from 1.5 Feet to 60 Feet. Your distance measurer transmits ultrasonic waves to a point you want to measure. Afterward, it measures the time taken by the waves to reflect and then calculates and re-transcribes the distance.
