RealVü 3D Forward Sonar View
This sonar view shows a three-dimensional view of what is in
front of the transducer. This view can be used when you are
stationary and you need to see the bottom and the fish
approaching the boat.

RealVü 3D Down Sonar View
This sonar view shows a three-dimensional view of what is
below the transducer and can be used when you are stationary
and want to see what is around your boat.
RealVü 3D Historical Sonar View
This sonar view provides a three-dimensional view of what is
behind your boat as you are moving and shows the entire water
column in 3D, from the bottom to the top of the water. This view
is used for finding fish.

FrontVü Sonar View
The Panoptix FrontVü sonar view increases your situational
awareness by showing obstructions under the water, up to
91 meters (300 feet) in front of the boat.
The ability to effectively avoid forward collisions with FrontVü
sonar decreases as your speed rises above 8 knots.
To see the FrontVü sonar view, you must install and connect a
compatible transducer, such as a PS21 transducer. You may
need to update the transducer software.

Selecting the Transducer Type

Before you can select the transducer type, you must know what
kind of transducer you have.
This chartplotter is compatible with the Garmin ClearVü
transducer as well as a range of accessory transducers
including Garmin GT transducers, which are available at
www.garmin.com. For information about compatible
transducers, go to www.garmin.com/transducers.
If you are connecting a transducer that was not included with the
chartplotter, you may need to set the transducer type to make
the sonar function properly. If the device automatically detected
your transducer, this option does not appear.

From a sonar view, select Menu > Sonar Setup >
Installation > Transducer Type.
2
Select an option:
• If you have a 200/77 kHz, dual-beam transducer, select
Dual Beam (200/77 kHz).
• If you have a 200/50 kHz, dual-frequency transducer,
select Dual Frequency (200/50 kHz).
• If you have another type of transducer, select it from the
list.

Calibrating the Compass

Before you can calibrate the compass, the transducer must be
installed on the shaft 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: To use the compass, you must mount the transducer on
the shaft. The compass does not work when you mount the
transducer on the motor.
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.
