Garmin Foot Pod - GPS receiver wireless step sensor

Take it inside! Now you can train indoors with your Forerunner 305 and still track your distance, pace and calories burned. The wireless Foot Pod attaches to your running shoe (threads through the laces for a secure fit) and transmits your distance and pace to the Forerunner. Use the Foot Pod on an indoor track, treadmill or anywhere you can't get GPS satellite signals. Unlike step counters, the Foot Pod can accurately report your distance traveled whether you're walking, jogging or sprinting. For even more accurate data, you can calibrate the Foot Pod to adjust for your personal stride mechanics. Foot Pod is compatible only with the Forerunner 305.
