I have a digital scale I have been using for about 7 years now and when I check my weight I usually don't do it just once, I do it a couple of times because the scale often changes. For example, the first weight will be say 202 and then when I get on again it says 200 or 203 or some variation. It's very hard to know what I have lost this way.
I went to a home store and tried out a digital scale there and same thing. It said 204 or 203 then changed by a pound each time.
Finally I tried a mechanical scale (the old fashioned one with the wheel!) and it told me I was 199 lbs and I stepped on it like 4 or 5 times and got pretty much the same result each time.
So my question is, which type of scale is the most accurate and trustworthy? Is there a specific brand you can recommend? Also, which weight should I go with? The 202 or 199? And should I get a mechanical scale over a digital?
