My dr's office has the usual scale moving a big block and a smaller one until the scales balance (don't know what it's called--traditional, mechanical scale) and it tells me I'm about 9 lbs more than the scale I use at work (one with the dial that goes around). I'm going with the one at work --not only because it says I'm less but because it's available to me. How often do I go to my Dr's office, anyway?

IMO, you just have to pick one and stick with that one. If you pick the digital, change your stats on the forum and use that scale from now on.

Good luck and happy weighing
