BF% measurement products.

[Zyglamail]

Im looking for some opionins on various methods of measuring BF. I have a nice set of calipers, but for the life of me can never get consitent readings. I was thinking of going the electronic route and was wondering if anyone had any experience with such products.....things like reliability and accuracy, how do they compare to calipers.......yeah, I realize these arent cheap.

Thanks for any input.
