    A person performing the Bod Pod correctly knows you need to wear a swimming cap and calibrate it between each testing. It's hard to explain, easier to look up but the Bod Pod measures with air volume on your body and lung expansion and air trapped in hair whether excessive body hair for men or long hair for women can mess with the results. Hence the need for swimming caps. I trust the bod pod and callipers over any hand held device or online calculator. There are too many factors that go into calculating the % that the latter 2 just can't test.

    What are the many factors that you are talking about?

    i got this off a bodybuilding forum. i have a device at home now which measues BF and the two results for me are pretty close, hence my saying its pretty acurate.

    just incase anyone was doin it wrong heres an example....

    if you weigh 150lbs and have a 29" waist - step 1 is (150 x 1,082) + 94,42 = 256,72
    step 2 says that lean bodyweight is 256,72 - (29 x 4,15) = 136,4
    finally step 3 says that BF is (150 - 136,4) x 100 divided by 150 = 9,07%

    total body weight is what you see on the scales......
    lean body weight is minus the fat.

    also, makes sure you are measuring your WAIST not HIPS.

    works for me, just thought id share it since you were askin for a cheap way to measure bf.

    cheers

    also, makes sure you are measuring your WAIST not HIPS.

    Natural waist (smallest circumference of the abdomen) or navel (largest part of abdomen, for me anyway)? When you say 'waist' I'm not sure which one you're referring to, since I see different I structures on different bodyfat calculators. There is a significant difference in those 2 measurements for me (probably 3 or 4 inch difference, maybe a tiny bit more or less, haven't measured in a few weeks) so I'm wondering which one I'm supposed to use. Want to try out your formula. :-)
