Polar G1 provides speed and distance data in all outdoor sports using Global Positioning System (GPS) technology.

The Polar G1 sensor determines your location by measuring continuously the distance between itself and at least four satellites. The sensor uses wireless transmission technology to transmit speed and distance data to a compatible Polar product which records and displays the data.

Polar G1 is resilient and water resistant - you can depend on its performance regardless where you train!
