My scale was $25 at Target. It's internally spot on. Maybe you just got a junk unit.
Thanks for the info. I'll do a search and see what I can find. As mentioned in my title, I found that hydration has a big effect on the Body Fat % measurement. I jumped on the scale after three hours of cycling and saw my Body Fat % had increased by 3%. In all fairness this is mentioned in the scales instruction manual.wasfast said:Do a search about the Tanika scales as there have been several threads in the past. The weight aspect is very repeatable as you say and pretty accurate also. The body fat percentage is mostly for reference and can't be counted on for accuracy. It's highly variable based on hydration. Too little water and your body fat percentage will show higher. Plenty of hydration and the number will be lower.
I've had mine (less elaborate model than yours) for a couple years now and am satisified. I just wouldn't be using it as a gold standard for body fat amount.
