The most economical way to get body fat measured is to use body fat calipers, I myself have been using calipers for a few years but also have a body fat scale. I once had my body fat measured at the gym and they use a special machine to get it measured via electrical signals I believe.
The most accurate way to find body fat levels is through autopsy LOL but thats not an option now is it?
With anything all the above methods are tools and all have degrees of accuracy I would pick one and stick with it. When I get measured via my body fat scale I get a reading of 20% and calipers I get 11.5% LOL.
