This is the digital bathroom scale that measures body fat and muscle mass for specific areas to help users monitor the effectiveness of exercise and diet programs more closely. With the press of a button, the scale displays individual fat percentage and muscle mass readings for each leg, each arm, and the trunk. Stainless steel electrodes on the scale's surface and handheld sensor generate a harmless electrical impulse (Bioelectrical Impedance Analysis) to obtain readings, a method proven to be more accurate than the body mass index method used by lesser scales. It also measures overall bone mass, BMI, Visceral fat, body water percentage, metabolic age, and Daily Caloric Intake. The scale has a 330-lb. capacity and displays readings in 0.2 lb./0.1 kg increments on a large LCD panel. It stores readings for up to four users, allowing a family to easily track progress. Includes four AA batteries. 13 1/2" H x 12 1/2" W x 2 1/4" D. (5 lbs.)
