POD 2 Watch Sensor Accessory, Indoor and Treadmill Distance Tracking More Sensitive Real-time Pace, Improves GPS Data, Clip onto Shoes or Waistband only Works with Watches

POD 2 measures your run directly from your foot or body movements with optimized sensor hardware and intuitive software algorithms. It connects to your watch to provide real-time data, so you can always train or race with the right information.
MORE SENSITIVE INSTANT PACE: With the advanced accelerometer in POD 2, receiving data directly from your foot to create the most responsive pace displayed on your watch. It removes the up to 10-second delay caused by the GPS watch's wrist sensors. A watch paired with the POD 2 ensures you can stay within your targeted pace in nearly real-time, even when there is no GPS signal.
MORE ACCURATE DISTANCE INDOORS: With accurate pace detection, POD 2 measures the exact distance you've run, even when indoors. By plotting the motion of your foot through space on an XYZ plane, the POD 2 automatically calibrates itself to calculate your stride and the distance you've run on a treadmill, or an indoor track.
MORE PRECISE ON HILLY TERRAIN: Effort Pace is a unique metric that tells you how hard you're actually working when on hilly terrain. The POD 2 makes your Effort Pace 5x more responsive than standard GPS, so you can make split-second decisions and better analyze your overall exertion once a workout has ended.
MORE CONSISTENT IN THE CITIES: Running through tunnels or the first few miles of the Chicago marathon between skyscrapers not only disrupts your watch's pace and distance data but also creates messy GPS tracks. With data gathered from various internal sensors, POD 2 is able to auto-correct GPS disruptions such as pace spikes and drops. POD 2 is only compatible with watches except for PACE1
