The RS200 Foot Pod is a exercise management system. The RS200 can be used to monitor the wearer's heart rate, track the wearer's distance covered, calculate the amount of calories burned and so on. The RS200's "Run Distance" calculator can be calibrated by setting a distance, running or walking the specified distance and then indicating that the distance has been reached. If you find that your calculated running distances are way off, you can manually calibrate your RS200 for more accurate results.
If you're a runner or walker, sometimes you want to measure not only how long you exercise but also how far you have gone. Foot pod technology does just that. Manufacturers such as Polar and Garmin make foot pods that will help consumers manage their workouts by measuring distance and pace.
A Garmin Foot Pod is an advanced pedometer that can estimate how far you've walked or run, and give you an estimated speed. It can be paired with other electronic devices, such as heart rate monitors, to provide you with more options. Calibrating the device to your walking or running speed allows the unit to more accurately estimate your speed and distance. It is an optional feature.
