Garmin Ant+ Foot Pod for use with Ant+ devices or software such as Zwift Running.

Useful for tracking cadence and a more accurate distance when running on a treadmill or if your watch loses GPS signal. Essential for serious runners over winter.

Second picture shows it connected to my Garmin watch just to show its working. Obviously sale won't include a Garmin Fenix.

Garmin no longer produce foot pods and are therefore difficult to get hold of.

Comes with a print out of the instructions.
