How precise is the GPS tracking?

GPS Tracking frequency is dynamic - it depends on whether the boat is turning, going straight or not moving at all. The resulting tracks are very detailed as can be seen in this image:
For performance reasons the points may be slightly sparser when displaying the routes on your computer, phone or tablet. You can download the full track using the "Download GPX" button on any route in the web app.
