The Tanita BC-1000 body composition monitor is ideal for athletes and fitness users who need to accurately monitor parameters like weight, body fat and hydration level. The scale uses ANT+™ technology to wirelessly transmit your data to the FR60 or Forerunner 310XT. Weight, body fat and body water are displayed on the watch, and six additional measurements are stored, then sent to Garmin Connect when in range of your computer.
