Setting The Bow Offset; Calibrating The Compass - Garmin GPSMAP 9 3 Series Owner's Manual

Setting the Bow Offset

For forward view Panoptix transducers, you can enter a bow offset to compensate the forward distance
readings for the transducer installation location. This allows you to view the forward distance from the bow
instead of the transducer installation location.
This feature applies to Panoptix transducers in the Garmin FrontVü, LiveVü Forward, and RealVü 3D Forward
sonar views.
1 Measure the horizontal distance from the transducer to the bow.
2 From an applicable sonar view, select Options > Sonar Setup > Installation > Bow Offset.
3 Enter the distance measured, and select Done.
On the applicable sonar view, the forward range shifts by the distance you entered.

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.
NOTE: 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.
NOTE: Compass calibration is available only for transducers with an internal compass, such as the PS21-TR
transducer.
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.
2 If necessary, select Use AHRS to turn on the AHRS sensor.
3 Select Calibrate Compass.
4 Follow the on-screen instructions.
