AS TOOL CENTER CP-3007 High Quality LCD Ultrasonic Distance Meter Measure + Laser Pointer Non-magnetic Engineer's Precision Level  (1800 cm)

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 o 60 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. Constructed to work on the roughest and dirtiest jobsites, this ultrasonic distance measurer provides a reliable, accurate and fast way to measure distances and calculate the area and volume of any space. It's perfect for determining ceiling heights, calculating length of pipe, cable, or estimating materials such as paint, drywall, flooring, etc 100% Brand new, high quality. LCD with Backlight.
