Calibrating the Compass

Before you can calibrate the compass, the transducer must be installed far enough away from the trolling motor to avoid magnetic interference, and deployed in the water. Calibration must be of sufficient quality to enable the internal compass.

NOTICE

The compass may not work if you mount the transducer on the motor.

NOTE: For best results, you should use a heading sensor such as the SteadyCast™ heading sensor. The heading sensor shows the direction the transducer is pointing relative to the boat.

You can begin turning your boat before calibrating, but you must fully rotate your boat 1.5 times during calibration.

  1. From an applicable sonar view, select Options > Sonar Setup > Installation > Calibrate Compass.
  2. Follow the on-screen instructions.
The compass is calibrated for your transducer orientation.
NOTE: If you change the transducer orientation, you may need to recalibrate the compass.
