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
This feature may not be available on all chartplotter models.
You can view the sonar data from other chartplotters with a built-
in sonar module connected on the Garmin
Marine Network.
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 a transducer with
Garmin
ClearVü mounted at the back of the boat, you can view the
sonar data using the 93sv
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
have adjusted the level of detail shown on the screen using the
gain or brightness settings.
If you want to highlight smaller fish targets or create a higher
intensity display of a target, you can increase the color gain or
contrast setting. This causes a loss in the differentiation of the
high intensity returns at the bottom. If you want to reduce the
intensity of the return, you can reduce the color gain or contrast.
