Exactly. With these devices, it is very difficult to accurately estimate body fat % because distributions do vary quite a bit; without a sex selector, they are useless because they have no way to differentiate between android and gynoid fat distributions. Even then, they are guesses. The typical skinfold assessment is comprised of about 7 sites for a reason.
Impedance devices are highly skewed by hydration status, as well.
reminds me of the time I had a free "health assessment" as part of a new gym membership. The impedance device told me I had 3% body fat. Uh huh. Tell that to the DXA that just told me 8%.
