Scale that will calculate bf %?

[copracr]

I found this scale in popsci magazine that says that by running a small current from foot to foot it can tell you your bf% and hydration levels. Does anyone have one of these things?
Do you think if I have calloused feet that it wouldn't be accurate? They are only about 100 bucks so if a few people have had good results then i'd like to get one, but i'm skeptical.

I don't think they are very accurate man. I have a set at home and they constantly say i am between 25 and 30% bf.
my physio has a set that are suppossed to be the "sports model" and they measure me at about 22%
Personally i think i am about 17-20%, I posted pics recently and everyone said I was low teens.
you are probably better off just looking in the mirror and guessing it, or if you want an accurate read, get a calliper skin fold test

I am considered obece on those scales, even thought I have 8%bf.

I returned one right away.

Get a fat caliper.

I've got a set, bought from Academy for like $69. They're very good for tracking changes in BF, but poor for pinpoint accuracy. (i.e. I may read 15% in the morning and 11-12% by bedtime).

I've found that they measure within about +/- 3% of what's true - my average right now is somewhere around 13%, and according to calipers, I'm right at 12-13%.

Also, Inked, if possible make sure they're set on "Athlete" setting instead of "Adult." For people with more muscle mass, that's much more accurate. (for example, I measure at 17%+ on Adult, but average 13% on Athlete - the same % as with calipers.)

I am not a fan of bioelectrical impedence. I always get highg readings. During undergrad we did calipers and I was at 14% and then we did hydrostatic and I was 13% and then we did Bioimpedence and i was 19%. They suck as far as I am concerned. They depend too much on hydration levels
