If you are older than me you probably know how these work. Heck, who wants to use electric scales when you can go to the trouble of carefully sliding, turning and tapping metal weights up and down a plastic beam to see how well items balance weight? Head back to dark ages with these twin beam scales, accurate to 1% and highly unlikely to ever run out of battery. If your twin beam scales do run out of battery please do not contact us. We have run out of twin beam weighted scale batteries.
Please note Zen Twin Beam Scales do not require any form of power or electricity.
