Body Fat Analyzer
So what's the difference between a hand held body fat analyzer and a set of body fat scales?
Other than being a little more portable and lightweight... very little. They both use exactly the same technology as each other and produce a similar level of accuracy and consistency.
Analyzers and scales are also priced similarly. Omron make a model for under $60 (about the same as the lowest priced set of scales). The only real difference is that scales double as weighing scales. It's this fairly insignificant point that, in my opinion, gives a bit of an edge.
My advice? Read the article on body fat scales. The technology behind the two devices is identical plus you may want to consider an alternative to a analyzer...
