Sonin Multi-Measure Combo Pro

SONIN Electronic Distance Measuring Tools send out narrow beams of sound waves that "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. (When used with its electronic target, the Combo PRO model uses both sound waves and an infrared beam.) Every SONIN Electronic Distance Measuring Tool has a built-in calculator to add linear measurements and compute areas and volumes. Intelligent software, improved accuracy and easy-to-understand instructions complete the attractive package. Measures from 1'6" Up To 60 Feet(18 meters) in single unit mode.
