How do you determine your BF%?

[PurplePatriot]

I have used all types of stand on scales that estimate body fat as well as the hand held type and they generally all say the same % to within .2-.4% points. And yet everyond keeps telling me most of these are bogus? Is technology really that bad? I know not everyone here has access to go jump underwater and all that crap to get an exact reading. How do you guys determine your bf% without going underwater?

Bodyfat calipers. Search for them on bodybuilding.com or any other similiar site... They aren't as accurate as underwater..but theyre close enough and theyre cheap
