COROS Tips

Since all 3 devices are very similar in features the tips are identical:

Set up the device correctly prior to speed sailing.
- I thoroughly recommend using the guide by Ingolf van Oostveen.
- Use the auto-sync feature on GP3S so that sessions can be posted quickly and easily.
When exporting tracks for analysis, always choose the FIT file format over GPX.
- FIT files from sports watches tend to include Doppler speed in addition to latitude and longitude. FIT files also include metrics such as heart rate, temperature, etc.
- COROS have also added some useful GPS information to the FIT data, enabling run verification for GP3S; Satellites, COG, HDOP.
- GPX files contain latitude and longitude but not Doppler speed. Speeds calculated from positional data are less accurate than Doppler speeds and prone to “spikes”.
Avoid using GPS modes including GLONASS.
- “GPS, Beidou, Galileo, QZSS” works well for most of Europe, including the UK.
The feature to start / stop recording on your GoPro (or similar) could be really handy.
Learn how to mark your current position, just in case of unfortunate incidents…
- For example, if you lose your foil or GoPro, quickly mark your position!
- Whilst in windsurf mode, hold down the back/lap button and select “save location”.
It is worth noting that tracks appear to be stored on the COROS servers, not within the COROS app on your phone.
- During a remote walk with no mobile reception, I couldn’t see any of my past APEX Pro sessions on my phone.
