Electronic bf calculator

[BigB_79]

Anyone ever use one of those electronic bf calculators that some gyms have? You enter your sex, age, height, and weight, press start and you hold onto some sort of metal handle. After a few seconds it gives you your bf %. Does anyone believe these are accurate???

no

Def. not accurate. Your reading can change drastically depending on your hydration level as it sends an electrical impedance through and measures the time it takes to return. Also it does not account for the lower half of the body. it merely measures the length of time it takes for the impules to go from one hand through the body to the other hand. so bf% from other areas arent accounted for.

They are not accurate. We sometimes use them in the medical office, but they have a reliability of +/- 7%; Calipers are a better solution without going through the water measurement.
