Frequently Asked Questions
Why is this needed?
At Surfr we have the unique mission that we want to support all devices, all brands, and all platforms. To accomplish accuracy across the board we have developed a unique calibration method that boosts accuracy and consistency.
My device didn't ask for the extended calibration, can I still do it?
If your device didn’t ask for the extended calibration (step 2 till 6) it means that your device is fairly good by default, there is no need for extended calibration.
Is it needed to redo calibration once in a while?
Based on our tests we don’t think so. But in case you start noticing problems, you can always try to re-calibrate via Settings. If that doesn’t help your issue, please contact us.
I get a frequency error during calibration (Wear OS)
Surfr requires a frequency of at least 100 HZ. This means that we will receive 100 measurements per second to be able to do accurate height tracking. If you get stuck at lower frequencies your device might not be good enough for Surfr. Before you give up, make sure to try to increase your screen time-out of the device.
1) Go to the settings of the Wear OS watch
2) Find Display.
3) Change the screen timeout to as long as possible (30 seconds or more). And also check the ‘always on Display’ check box if available.
4) Try the calibration again.
Once you finish the calibration you can set the screen timeout setting back to the desired/original values.
