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.
Helping you to train smarter
Runsense lets you track your progress against long-term targets designed to improve your performance. The free Runsense View portal and Run Connect app1 help you customise your settings, and monitor, analyse, compare and even share your stats to maximise your potential. Connect to your smart device using Bluetooth Smart. Just tap to cycle through four customisable screens, with up to three measurements on each, chosen from a huge range of options.
Train your way, for longer
An impressive, combined GPS and heart rate-monitoring battery life of 20 hours - 2.5x longer than comparable competitor products2 - means you can run for longer before recharging. Set customisable phases for interval training, variable target pacing and laps to suit your regime, or use the indoor mode. The SF-810 is water resistant up to 5ATM, and has a compact, lightweight design.
