I'm seeing an error in my goggles during an open water swim with a smartwatch
There are three possible errors you may see in your goggles display during an open water swim with a smartwatch.
In all cases, the data will continue to be recorded on your watch. The timer will continue to count in the goggles during this time. The display will refresh completely and show the latest metrics the next time the goggles are able to connect to the watch.
Error one: “watch disconnected”
This means that the connection between the goggles and the smartwatch has been lost. Continue swimming normally to allow them to reconnect. If you are resting, try raising your arm out of the water to allow the connection to take place.
When reconnected, all the displayed metrics and timer will update to the current state on the watch.
Error two: “no GPS signal”
This means that the smartwatch has lost GPS signal. Try holding your arm out of the water to reconnect. If you are using an Apple Watch, try to wait for a stronger GPS signal before starting your swim so that the connection is more easily maintained.
Error three: “no HR signal”
This means that there is no heart rate reading coming from the watch, or that the reading is old. If possible, try tightening the watch strap.
Please note that the accuracy of optical heart rate measured from the wrist in open water swimming varies from athlete to athlete.
