Configuring the Heading Source of the Wind Gauge
You can specify the source of the heading displayed on the wind gauge. Magnetic heading is the heading data
received from a heading sensor, and GPS heading is calculated by your chartplotter GPS (course over ground).
1 From the wind gauge, select Options > Edit Gauge Pages.
2 In the window on the left, select Compass Gauge.
3 Select Heading Source, and select an option:
• To use heading data received from a heading sensor, select Magnetic.
• To use heading data calculated using GPS, select GPS.
NOTE: When moving at low speeds or when stationary, the magnetic compass source is more accurate than
the GPS source.

select Change Upwind Scale, and set the angles.
• To set the maximum and minimum values that appear when the downwind close-hauled wind gauge
