This intelligent Electronic Distance Measuring Tool sends out narrow beams of ultrasonic waves that ‘bounce’ off solid objects back to the hand-held receiver, a microprocessor then converts elapsed time into a distance measurement and displays it on the LCD.

Built-in laser reference can be used to improve its accuracy. This Ultrasonic Distance Estimator tape is reliable, accurate, precise and easy to use. Areas and volumes can be easily and conveniently calculated by simply pressing a few button.
