Perspective View
This sonar view shows a live view of what is around and ahead
of your boat and can be used to see shorelines, fish, and
structures. This view is best used in shallow water of 50 feet
(15 meters) or less.
To see this sonar view, you must install a Panoptix LiveScope
transducer on a Perspective Mode Mount (010-12970-00).
Selecting the Transducer Type
This chartplotter is compatible with a range of accessory
transducers, including the Garmin ClearVü
™
transducers, which
are available at 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.
NOTE: Not all chartplotters and sonar modules support this
feature.
1
Complete an action:
• From a sonar view, select Menu > Sonar Setup >
Installation > Transducers.
• Select Settings > My Vessel > Transducers.
2
Select an option:
• To enable the chartplotter to detect the transducer
automatically, select the transducer to change, and select
Auto Detect.
• To select the transducer manually, select the transducer
to change, select the transducer model from the list, and
select Change Model.
NOTE: If you select the transducer manually, disconnect
that transducer, and then connect a different transducer,
you should reset this option to Auto Detect.
Selecting a Sonar Source
This feature may not be available with all models.
When you are using more than one sonar data source for a
particular sonar view, you can select the source to use for that
sonar view. For example, if you have two sources for Garmin
ClearVü, you can select the source to use from the Garmin
ClearVü sonar view.
1
Open the sonar view for which you will change the source.
2
Select Menu > Sonar Setup > Source.
3
Select the source for this sonar view.
Renaming a Sonar Source
You can rename a sonar source to easily identify that source.
For example, you use "Bow" as the name of the transducer on
the bow of your boat.
To rename a source, you must be in the applicable sonar view
for the source. For example, to rename the Garmin ClearVü
sonar source, you must open the Garmin ClearVü sonar view.
1
From the sonar view, select Menu > Sonar Setup > Source
> Rename Sources.
2
Enter the name.

Sonar Sharing
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,
no matter where the chartplotters and transducers are mounted
on your boat. For example, from one GPSMAP 923 device
mounted at the back of the boat, you can view the sonar data
from another GPSMAP device and Garmin ClearVü transducer
mounted at the front of your boat.
When sharing sonar data, the values of some sonar settings,
such as Range and Gain, are synchronized across the devices
on the network. The values of other sonar settings, such as the
Appearance settings, are not synchronized and should be
configured on each individual device. In addition, the scroll rates
of the various traditional and Garmin ClearVü sonar views are
synchronized to make the split views more cohesive.
NOTE: Using multiple transducers simultaneously can create
cross talk, which can be removed by adjusting the Interference
sonar setting.
Adjusting the Level of Detail
You can control the level of detail and noise shown on the sonar
screen either by adjusting the gain for traditional transducers or
by adjusting the brightness for Garmin ClearVü transducers.
If you want to see the highest intensity signal returns on the
screen, you can lower the gain or brightness to remove lower
intensity returns and noise. If you want to see all return
information, you can increase the gain or brightness to see more
information on the screen. This also increases noise, and can
make it more difficult to recognize actual returns.
1
From a sonar view, select Menu.
2
Select Gain or Brightness.
3
Select an option:
• To increase or decrease the gain or brightness manually,
select Up or Down.
• To allow the chartplotter to adjust the gain or brightness
automatically, select an automatic option.
Adjusting the Color Intensity
You can adjust the intensity of colors and highlight areas of
interest on the sonar screen by adjusting the color gain for
traditional transducers or the contrast for Garmin ClearVü and
SideVü/ClearVü transducers. This setting works best after you
