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.
Creating a Waypoint on the Sonar Screen
1
From a sonar view, drag the screen or select .
2
Select a location.
3
Select New Wpt or .
4
If necessary, edit the waypoint information.
Pausing the Sonar Display
From a sonar view, select .
Viewing Sonar History
You can scroll the sonar display to view historical sonar data.
NOTE: Not all transducers save historical sonar data.
1
From a sonar view, drag the screen to the right.
2
Select Back to exit history.
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,
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 GPSMAP A12 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.
1
From a sonar view, select Menu .
2
Select an option:
• While in the Garmin ClearVü or SideVü sonar view, select
Contrast .
• While in a Panoptix LiveVü sonar view, select Color Gain .
• While in another sonar view, select Sonar Setup >
Appearance > Color Gain .
3
Select an option:
• To increase or decrease the color intensity manually,
select Up or Down .
• To use the default setting, select Default .
Sonar Recordings
Recording the Sonar Display
NOTE: Not all models support sonar recording.
1
Insert a memory card into the card slot.
2
From a sonar view, select Menu > Sonar Setup > Sonar
Recording > Record Sonar .
15 minutes of sonar recording uses approximately 200 MB of
space of the inserted memory card. An individual recording
automatically ends after it reaches 4 GB in size. You can
record sonar data until the card reaches capacity.
Stopping the Sonar Recording
Before you can stop recording sonar, you must begin recording
it ( Recording the Sonar Display , page 26 ).
From a sonar view, select Menu > Sonar Setup > Sonar
Recording > Stop Recording .
Deleting a Sonar Recording
1
Insert a memory card into the card slot.
2
From a sonar view, select Menu > Sonar Setup > Sonar
Recordings > View Recordings .
