This Total Body Composition Monitor measures your weight including body fat and body water as a percentage of your total weight, making it the perfect gift for health conscious folks as they keep track of their weight before the onslaught of fatty foods that come our way every holiday season. Accurate readings are garnered from Bioelectric Impedance Analysis (BIA) that uses harmless electrical signals from foot sensors, and these results are displayed on a color LCD. The glass-and-metal scale measures 13" in diameter and is powered by a single 9V battery, retailing for $119.95.
Other scales of this genre send a “harmless electric signal up one leg and down the other giving a reading of the lower portion of the body only — specifically the legs. How, exactly, does this scale differ — how is it able to “read” the “total body composition”?
