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 a range of accessory
transducers, including the Garmin ClearVü ™ transducers, which
are available at 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 detects
your transducer, this option does not appear.
1
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.

Sonar Sharing
This feature may not be available on all chartplotter models.
You can view the sonar data from all compatible sources on the
Garmin Marine Network. You can view sonar data from a
compatible external sonar module, such as a GCV ™ sonar
module. In addition, you can view the sonar data from other
chartplotters that have a built-in sonar module.
Each chartplotter on the network can display sonar data from
every compatible sonar module and transducer on the network,
