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 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.

From the sonar view, select

.
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 and SideVü/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.

Select an option:
• To increase or decrease the gain or brightness manually,
select

.
• 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 DownVü and SideVü/
DownVü 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.

Adjusting the Range of the Depth or Width
Scale
You can adjust the range of the depth scale traditional and
DownVü sonar views and the range of the width scale for the
SideVü sonar view.
Allowing the device to adjust the range automatically keeps the
bottom within the lower or outer third of the sonar screen, and
can be useful for tracking a bottom that has minimal or moderate
terrain changes.
Manually adjusting the range enables you to view a specified
range, which can be useful for tracking a bottom that has large
terrain changes, such as a drop-offs or cliffs. The bottom can
appear on the screen as long as it appears within the range you
have set.

Setting the Scroll Speed
You can set the rate at which the sonar image moves across the
screen. A higher scroll speed shows more detail, especially
while moving or trolling. A lower scroll speed displays sonar
information on the screen longer. Setting the scroll speed on
one sonar view applies to all the sonar views.

Select an option:
• To adjust the scroll speed automatically using speed-over-
ground or water speed data, select
Auto
.
The Auto setting selects a scroll rate to match the boat
speed, so targets in the water are drawn with the correct
aspect ratio and appear less distorted. When viewing
DownVü or SideVü sonar views, it is recommend to use
the Auto setting.
• To use a very fast scroll speed, select
Ultrascroll®
