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.

Turning On the A-Scope
NOTE: This feature is not available in all sonar views.
The a-scope is a vertical flasher along the right side of the full-
screen sonar view. This feature expands the most recently
received sonar data so that it is easier to see. It can also be
helpful for detecting fish that are close to the bottom.
From a sonar view, select Menu > Sonar Setup >
Appearance > A-Scope.

From a sonar view, select Menu > Sonar Setup.
Depth Line: Shows a quick-reference depth line.
Scroll Speed: Sets the rate at which the sonar scrolls from right
to left.
In shallow water you might want to slow the scroll speed to
extend the length of time the information is displayed on
screen. In deeper water you can increase the scroll speed.
On-screen Control: Sets the behavior of the buttons on the
sonar screen control. This is available for touchscreen
devices.
Range Lines: Shows the vertical lines indicating the distance to
the right and left of the boat. This setting is available for
SideVü sonar view.
Color Scheme: Sets the color scheme of the sonar view. This
setting might be available in the Appearance menu.
The high contrast color schemes provide darker color
assignments to the low intensity returns. The low contrast
color schemes provide color assignments to the low intensity
returns that are similar to the background color.

Sonar Appearance Settings
From a sonar view, select Menu > Sonar Setup > Appearance.
Color Scheme: Sets the color scheme.
Edge: Highlights the strongest signal from the bottom to help
define the hardness or softness of the signal.
A-Scope: Displays a vertical flasher along the right side of the
screen that shows instantaneously the range to targets along
a scale.
Pic. Advance: Allows the sonar picture to advance faster by
drawing more than one column of data on the screen for
each column of sounder data received. This is especially
helpful when you are using the sounder in deep water,
because the sonar signal takes longer to travel to the water
bottom and back to the transducer.
The 1/1 setting draws one column of information on the
screen per sounder return. The 2/1 setting draws two
columns of information on the screen per sounder return, and
so on for the 4/1 and 8/1 settings.
Fish Symbols: Sets how the sonar interprets suspended
targets.
Advanced Sonar Settings
NOTE: Not all options and settings apply to all models, sounder
modules, and transducers.
