A Deep Dive Into The Epson Runsense SF-310

Epson Runsense SF-310 reviewed and tested by Tristan Haskins. Please note, at the time of writing this we have only tested the TOP of the range SF-810.

This SF-310 is the introductory model in the Epson Runsense GPS sports watch range, similar in functionality to the the Garmin Forerunner 10 with the added benefit of customisable screens.

If you want heart rate monitoring you will also need the optional HRM chest strap (or any Bluetooth 4.0 HR sensor).

Runsense SF-310 Features

The SF-310 features highly accurate GPS tracking and an amazing 30-hour battery life so you can dare to go another mile. You can view real-time data at a glance on its four customisable screens.

An advantage of the SF-310 over some other competitors products at a similar price is that you can view ALTITUDE data on the display. Most GPS sports watches will give access to altitude post session in the supported APP, but this one gives it LIVE on the display.
