This is the digital scale that supports your health and fitness regimen by quickly and accurately measuring key body composition data in addition to precise weight readings. Unlike other measuring methods that require expensive, specialized equipment or submersion in water, the scale uses bioelectrical impedance analysis (BIA) (a harmless electrical impulse) to calculate body fat percentage, muscle mass, and body water within seconds after you step on the 12 3/4 x 13 3/4" glass platform. Three modes (normal, child, and athlete) let you adjust the scale's sensitivity for greatest accuracy, and it estimates the daily caloric intake needed to maintain your current body composition. The scale can store data for up to 10 individuals, making it easy to track the entire family's progress. The 2" high LCD panel features a dual-line readout that displays weight and body composition results simultaneously in bright 3/4" high numerals. The scale has a 400 lb. (180 kg) capacity and displays weights in 1/4-lb. (0.1 kg) increments. Four AAA batteries (included) provide convenient cordless operation. 14 1/2" W x 13 3/4" L x 3" D. (4 lbs.)
