With such a difference, I think you need a third opinion. Either scale could have mechanical/battery issues. Obviously ONE of them was not correct. I have seen a 5 lb. difference among scales quite often - but a 39 lb. difference?
Is there another scale you can weigh on to determine which one is correct? Neighbor, friend, pharmacy, gym, office?
Susan is right - once you figure out which scale is accurate, stick with that one as your official weight.
