As it says, what do you all use? I'm told the handheld devices and scales are not accurate at all (even though the products claim to be pretty accurate). I want to do a daily weight and bf log but I don't feel like getting calipers out every morning just for that. I was using a little handheld omron (the one that looks like a little steering wheel that you squeeze and hold out in front of you) but what's the point if it's not accurate. Any suggestions?
