Off set
The compass off set compensates for fi xed errors (misalignment) between the compass sensor
and the direction of the boat.
To accurately enter a compass off set, the boat’s heading must be referenced to, for example:
a calibrated bowl compass . The off set value will be the diff erence between the known source
and the currently displayed heading. Enter this value as the off set in the compass heading
fi eld as a plus or minus integer up to 180º
Magnetic variation
Adjust how the system handles magnetic variation.
Auto
Automatically calculates variation based on position and date.
Manual
If variation is not available enter a value manually.
Use COG as heading
If heading data is not available from a compass sensor it is possible to use course over
ground from a GPS. COG will be used in the true wind calculations.
¼ Note: The autopilot cannot be operated using COG as the heading source. COG cannot be
calculated when stationary.
