Dual ultrasonic distance meter with laser pointer,LCD screen,200feet/60M measuring

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 2 Feet to 200 Feet. Your distance measurer transmits ultrasonic waves to a point you want to measure. Afterwards, it measures the time taken by the waves to reflect and then calculates and re-transcribes the distance.
