The Escali BFBW180 Ultra Slim Body Composition Scale features a stylish round platform and body composition measurements for an in-depth analysis of your body and your health. This scale uses Bioelectrical Impedance Analysis (BIA) technology to send an imperceivable electronic signal through your body to calculate body fat, body water, muscle mass, and bone mass. (Do not use this scale if you have a pacemaker or use any other electronic personal medical device.) Save up to 8 user profiles on the scale or let guests measure body weight without setting up a profile. Enable Athlete Mode if you have been exercising at least 10 hours per week for the past 6 months. Gender: unisex.
