From a sonar view, select Menu > Sonar Setup > Scroll
Speed.
2
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®.
The Ultrascroll option quickly scrolls new sonar data, but
with a reduced image quality. For most situations, the Fast
option provides a good balance between a quickly
scrolling image and targets that are less distorted.
Sonar Frequencies
NOTE: The frequencies available depend on the chartplotter,
sounder modules, and transducer being used.
Adjusting the frequency helps adapt the sonar for your particular
goals and the present depth of the water.
Higher frequencies use narrow beam widths, and are better for
high-speed operation and rough sea conditions. Bottom
definition and thermocline definition can be better when using a
higher frequency.
Lower frequencies use wider beam widths, which can let the
fisherman see more targets, but could also generate more
surface noise and reduce bottom signal continuity during rough
sea conditions. Wider beam widths generate larger arches for
fish target returns, making them ideal for locating fish. Wider
beam widths also perform better in deep water, because the
lower frequency has better deep water penetration.
Chirp frequencies allow you to sweep each pulse through a
range of frequencies, resulting in better target separation in
deep water. Chirp can be used to distinctly identify targets, like
individual fish in a school, and for deep water applications. Chirp
generally performs better than single frequency applications.
Because some fish targets may show up better using a fixed
frequency, you should consider your goals and water conditions
when using Chirp.
Some sonar black boxes and transducers also provide the ability
to customize preset frequencies for each transducer element,
which enables you to change the frequency quickly using the
presets as the water and your goals change.
Viewing two frequencies concurrently using the split-frequency
view allows you to see deeper with the lower frequency return
and, at the same time, see more detail from the higher
frequency return.
Selecting Frequencies
NOTE: You cannot adjust the frequency for all sonar views and
transducers.
You can indicate which frequencies appear on the sonar screen.
1
From a sonar view, select Menu > Frequency.
2
Select a frequency suited to your needs and water depth.
For more information on frequencies, see
Sonar Frequencies.
Creating a Frequency Preset
NOTE: Not available with all transducers.
You can create a preset to save a specific sonar frequency,
which allows you to change frequencies quickly.
1
From a sonar view, select Menu > Frequency.
2
Select Manage Frequencies > New Preset.
3
Enter a frequency.

Customizing the Panoptix Sonar Views
NOTE: Not all models support Panoptix transducers.
Adjusting the Appearance of the LiveVü Sonar Views
1
From a LiveVü sonar view, select Menu > Sonar Setup.
2
Select an option:
• To change the colors of the sonar view, select Color
Scheme, and select an option.
• To adjust the length of the trails that show target
movement, select Trails, and select an option.
• To distinguish the bottom from the water by coloring the
bottom brown, select Bottom Fill.
• To show or hide the range grid lines, select Grid Overlay.
• To hide or show the history on the side of the screen,
select Scroll History.
Setting the LiveVü Transducer Transmit Angle
You can change the LiveVü transducer transmit angle to aim the
transducer at a particular area of interest. For example, you
might aim the transducer to follow a bait ball or focus on a tree
as you pass it.
1
From a LiveVü sonar view, select Menu > Transmit Angle.
2
Select an option.
Adjusting the RealVü Viewing Angle and Zoom Level
You can change the viewing angle of the RealVü sonar views.
You can also zoom in and out of the view.
From a RealVü sonar view, select an option:
• To adjust the viewing angle diagonally, select
• To adjust the viewing angle horizontally, select
• To adjust the viewing angle vertically, select
• To adjust the viewing angle, swipe the screen in any
direction.
• To zoom in, spread two fingers apart.
• To zoom out, pinch two fingers together.
Adjusting the Appearance of the RealVü Sonar Views
1
From a RealVü sonar view, select Menu.
2
Select an option:
• To adjust the depth at which the color palette starts over,
select Palette Depth, and select an option.
• To select a different color palette for the sonar return
points, select Sonar Setup > Point Colors, and select an
option.
• To select a different color palette for the bottom, select
Sonar Setup > Bottom Colors, and select an option.
• To select a different style for the bottom, select Sonar
Setup > Bottom Style, and select an option.
• To hide or show the color legend on the side of the
screen, select Sonar Setup > Color Key.
Adjusting the RealVü Sweep Speed
You can update how quickly the transducer sweeps back and
forth. A faster sweep rate creates a less detailed image, but the
screen refreshes faster. A slower sweep rate creates a more
detailed image, but the screen refreshes more slowly.
NOTE: This feature is not available for the RealVü 3D Historical
sonar view.
1
From a RealVü sonar view, select Menu > Sweep Speed.

Select an option.
Turning On the A-Scope
NOTE: This feature is not available in all sonar views.
