Sinometer EM55 Digital Ultrasonic Measuring Tape - 50 Feet Laser Distance Meter for Home Improvement, Construction & DIY Projects

A revolutionary measuring gadget! Here's a device that can calculate length, width, area and even volume at the touch of a button. This intelligent Electronic Distance Measuring Tool sends out narrow beams of ultrasonic waves that can "bounce" off solid objects back to the hand-held receiver. Custom electronics and a microprocessor then convert elapsed time into a distance measurement and display it on the LCD. This Electronic Distance Measuring Tool has a built-in calculator to add linear measurements and compute areas and volumes. You can get results in meters or in feet. It's fool proof and simple to use: just point at a target, press a button , instant measurement, whether it's length, area or volume.
