Body Fat/Water Analyzer Fitness Scale by Salter

I can only tell you what my trainer told me. The readings from those types of scale can be very dependent on a lot of biological variables that will effect the readings. She said you can use it to get a general trend but you can't count on it for accurate body fat measurement.... they are useful to keep track over time to indeed confirm you body fat is trending downward....

I'm guessing your probably just as well off just depending on measurements to judge body fat loss. Save the money buy a decent scale to weigh on and a tape measure. Now if you have nothing else to spend those reward points on then it could be interesting info to have.
