How do they work?

Anyone who uses an ordinary tape measure will want a SONIN Electronic Measuring Tool when they see how convenient and easy-to-use it is.

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.) The Laser Targeting Range Finder adds a visible laser to assist the user in locating their target area.

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.
