I'm not sure about the scales but I know the hand held devices are not accurate, or least the one that the Gym used to test my body fat was not accurate.
It said that my body fat was 5%. At 5% I should be ripped but in reality I am not, I have a little bit of a gut and no six pack as of yet. I would guess that I'm between 10% and 12%.
I have heard that being properly hydrated makes a difference the electronic test. I consumed plenty of water before I had the test done.
