Performing Menu-Based Calibration

The heading sensor comes paired to your Spy™ pole. Before you can perform menu-based calibration, the Spy™ pole must be connected to a compatible Garmin^® chartplotter (Connecting to a Garmin Chartplotter).

You can calibrate your heading sensor from the menu of a compatible Garmin chartplotter.

From the home screen of your chartplotter, select Toolbars > Spy™ Pole.
Select a location for the Spy™ pole toolbar.
Open the Spy™ pole toolbar.
Select Menu > Installation > Calibrate > Spy™ Heading Sensor.
The calibration wizard opens.
Select Begin.
Follow the on-screen instructions until the compass calibration is complete, taking care to keep the boat as steady and level as possible.

The boat should not list during calibration.

If possible, you can turn the vessel in place by engaging two engines in opposite directions.

NOTE: If the heading performance is unacceptable after calibration, you may need to relocate the sensor and calibrate the compass again. Refer to the Spy™ pole installation instructions for further details.
Select Auto Heading Alignment.

NOTE: Auto Heading Alignment is available only if there is a GPS source present on the Garmin BlueNet™ network or Garmin Marine Network. If a GPS source is not connected, you must perform the Fine Heading Alignment instead (Adjusting the Fine Heading Alignment).
Select Begin.
Follow the on-screen instructions until the alignment is complete.
