Alto, unless you can get your hands (and the rest of you ) measured hydrostatically they are all to be taken with a few grains of nuSalt. What I have been doing is using 3 of the different methods and averaging the numbers. I will be acquiring some callipers shortly and using those, but even this has a 3% margin of error. When you're an athlete and every % counts 3% can make a lot of difference. However, when your goal is to have a healthy BF% I do not think sweating the details is necessary.

What I have learned from my research is this: measurements which take into account more than waist and hips are better. Wrist measurements have been linked to determining BF% so look for ones where this factors in. Ideally height should also be a function - 250 lbs on a 5'6" and 5'9" woman are going to give different %BF.
