The new smaller and lighter Suunto Foot POD wirelessly transmits speed and distance data to your Suunto Wristop Computer heart rate monitor, providing you a more complete analysis of your workout. It features accurate data collection during both indoor and outdoor workouts by measuring each stride with built-in acceleration sensors and speed limit alarms alert you if you’re going above or below your preset limits. When combined with the integrated altimeter of a Suunto T6 or T6c, you’ll get an even more complete picture of your performance–uphill, downhill, and on any terrain. It has a water resistance rating of 30 meters (100 feet), enabling it to withstand rain and splashes of water, but not swimming.
