Tanita curiosity

I have a Tanita body-fat scale that is probably about 5-6 years old. I am curious to see if anyone else has experienced something I have with theirs or a similar type scale.

First off, the scale normally indicates a BF% approximately 5% higher than one of these Omron hand-held body fat analyzers at my local gym.


I also have a set of Accu-Measure body fat calipers and use the Suprailliac Fold pinch test. I know single-measurement calipers aren't super accurate but they are usually with in 2-3% of the Omron analyzer at the gym.

However...after 8 weeks of consistent training and decent nutrition both the hand-held analyzer and the calipers showed a respective decrease in my BF%. The Tanita scale, on the other hand, actually changed very little, and when it did it actually showed an INCREASE in my BF%.

I can say with 99% confidence that my BF% did actually decrease slightly as my "gut" was visibly flatter and more muscle definition was evident.

Anybody else run into a "problem" like this?
 
Well it wouldn't let me edit the post above b/c it said I couldn't post URLs until I had 15 posts but it still posted the URL link anyway :dunno:

Anyhow...

ETA -- I have already tried fresh batteries and making sure the foot contacts are clean. I also always measure at the same time of day -- first thing in the AM right after I void.
 
the calipers will be more accurate than the scale is...

I have one of those scales (it was the only one that was available the day i went shopping)

the instuctions that come with the scale say pretty plainly - that it's not really going to be accurate based on a lot of factors -but what you want to note is a progression over time...

there's also a topic somewhereon this forum (try using the search feature) on body fat analyzers - there's a fairly description reasoning why even the hand helds can be off...
 
Yeah...what is really baffling me. The Tanita is showing an increase. The calipers and handheld both show a decrease that is similar. And the calipers show something similar to what a trainer at the gym asked if my BF% is around.
