Featuring cutting-edge Epson sensing technology, the SF-810 combines our highly-accurate, energy-efficient GPS chip and our Smart Stride Sensor that learns your running technique with a state-of-the-art built-in optical heart rate sensor. Reading your heart rate from your wrist, you can free yourself from chest straps forever. And it has 20 hours of battery life in GPS and heart rate measuring mode.
Accuracy and comfort
Always keep track of your progress with this accurate and intelligent GPS sports monitor, featuring smart device compatibility. Sync the SF-810 with your phone to enable fast GPS positioning with the AGPS function. The integrated optical sensor accurately monitors heart rate from your wrist without the need for a separate chest strap. Its Smart Stride Sensor measures stride length and pitch and learns your individual technique, so if GPS signal is lost, the SF-810 will keep track of your distance and pace.
