Changing the Sonar View
1
From a combination screen or SmartMode layout with sonar,
select the window to change.
2
Select Menu > Change Sonar .
3
Select a sonar view.
Selecting the Transducer Type
Before you can select the transducer type, you must know what
kind of transducer you have.
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.
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.
You can begin turning your boat before calibrating, but you must
fully rotate your boat 1.5 times during calibration.
1
From a ForwardVü or LiveVü Forward sonar page, select
Menu > Sonar Setup > Installation .
2 If necessary, select Use AHRS .
3 Select Calibrate Compass .
4
Follow the on-screen instructions.
Creating a Waypoint on the Sonar Screen
1
From a sonar view, select .
2 Select a location.
3 Select New Wpt or .
4
If necessary, edit the waypoint information.
Measuring Distance on the Sonar Screen
You can measure the distance between two points on the
SideVü sonar view.
1
From the SideVü sonar view, select a location on the screen.
2
Select Measure Distance .
A push pin appears on the screen at the selected location.
3
Select another location.
The distance and angle from the pin is listed in the upper-left
corner.
TIP: To reset the pin and measure from the current location of
the pin, select Measure Distance.
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, select .
2
Drag the screen.
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 DownVü
mounted at the back of the boat, you can view the sonar data
using the GPSMAP 7407xsv 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 DownVü 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.
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 DownVü,
you can select the source to use from the DownVü 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.
The source is renamed for the present view only. For example,
to rename the DownVü sonar source, you must open the
DownVü sonar view.
1
From the sonar view, select Menu > Sonar Setup > Source
> Rename Sources .
2
Enter the name.
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 DownVü 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 .
