    Most use the mirror I would say. Unless you get hydrostatic weighting or dex-scan, the margin of error is high or very inconsistent based off many variables. A general rule of thumb for error:

    Calipers + 8 measurement sites = +/- 3% to 5%
    Calipers + 4 or less= +/- 5%-7%
    Bioelectrical impedance (scales or hand held) = +/- 6%-10%


    Calipers are highly dependant on the person performing the test and what formula they use; the formulas vary with how many placements you use.

    Bioelectrical impedance is highly influenced by hydration levels.

    haha 6-10%, i have to agree on this for the hand held machines. i was at about 10% at one point, and i'm sure i was actually 14-16. it says i'm about 12% now. does that make me a potential 22% fatass? i'm probably more in the 14% range though.

    more importantly are they precise?

    if the scales are precise but not accurate, you can at the least track progress

    .


    I track my bodyfat from my tanita scale readings. I don't believe the numbers but at least they are consistent.

    I don't really care about the number, you could be a shitty looking 10% or a good looking 10%
