Locking compass calibration
The EV-1 sensor is designed to continually adjust its calibration settings in the background to improve its accuracy.
If your vessel is regularly in environments with strong magnetic disturbances (e.g.: offshore wind farms or busy rivers) it may be desirable to use the compass lock feature to prevent the continual adjustment, as over time this may cause an error in reported heading.
- Select EVO set-up from the This display menu.
- Select the Compass lock toggle switch so that it is enabled.
Note
You can disable the calibration lock at anytime by disabling the Compass lock toggle switch.
