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 > On.
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.

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.
Sonar Setup
NOTE: Not all options and settings apply to all models,
sounder modules, and transducers.
Sonar Settings
NOTE: These settings do not apply to Panoptix transducers.
See RealVü Sonar Settings and LiveVü Sonar Settings.
From a sonar view, select Menu > Sonar Setup.
Scroll Speed: Sets the rate at which the sonar scrolls from right
to left (Setting the Scroll Speed).
In shallow water, you can select a slower scroll speed to
extend the length of time the information is displayed on
screen. In deeper water, you can select a faster scroll
speed. Automatic scroll speed adjusts the scrolling speed to
speed the boat is traveling.

Noise Reject: Reduces the interference and the amount of
clutter shown on the sonar screen (Sonar Noise
Rejection Settings).
Appearance: Configures the appearance of the sonar screen
(Sonar Appearance Settings).
Alarms: Sets sonar alarms (Sonar Alarm Settings).
Advanced: Configures various sonar display and data source
settings (Advanced Sonar Settings).
Installation: Configures the transducer (Transducer Installation
Settings).
RealVü Sonar Settings
From a RealVü sonar view, select Menu > Sonar Setup.
Point Colors: Sets a different color palette for the sonar return
points.
Bottom Style: Sets the style for the bottom. When you are in
deep water, you can set this setting to the Points
and manually set the range shallower.
Bottom Colors: Sets the color scheme for the bottom.
Color Key: Shows a legend of the depths the colors represent.
Overlay Data: Sets the data shown on the sonar screen.
Installation: Configures the transducer (Transducer Installation
Settings).
LiveVü Sonar Settings
From a LiveVü sonar view, select Menu > Sonar Setup.
Sonar
Color Scheme: Sets the color palette.
Trails: Sets the how long the trails appear on the screen. The
trails show the movement of the target.
Grid Overlay: Shows a grid of range lines.
Noise Reject: Reduces the interference and the amount of
clutter shown on the sonar screen.
Scroll History: Shows the sonar history in a traditional sonar
view.
Overlay Data: Sets the data shown on the sonar screen.
Installation: Configures the transducer (Transducer Installation
Settings).
Sonar Noise Rejection Settings
From a sonar view, select Menu > Sonar Setup > Noise
Reject.
Interference: Adjusts the sensitivity to reduce the effects of
interference from nearby sources of noise.
The lowest interference setting that achieves the desired
improvement should be used to remove interference from the
screen. Correcting installation issues that cause noise is the
best way to eliminate interference.
Color Limit: Hides part of the color palette to help eliminate
fields of weak clutter.
By setting the color limit to the color of the undesired returns,
you can eliminate the display of undesired returns on the
screen.
Smoothing: Removes noise that is not part of a normal sonar
return, and adjusts the appearance of returns, such as the
bottom.
When smoothing is set to high, more of the low-level noise
remains than when using the interference control, but the
noise is more subdued because of averaging. Smoothing can
remove speckle from the bottom. Smoothing and interference
work well together to eliminate low-level noise. You can
adjust the interference and smoothing settings incrementally
to remove undesirable noise from the display.
Surface Noise: Hides surface noise to help reduce clutter.
Wider beam widths (lower frequencies) can show more
targets, but can generate more surface noise.
TVG: Adjusts the time varying gain, which can reduce noise.
This control is best used for situations when you want to
control and suppress clutter or noise near the water surface.
It also allows for the display of targets near the surface that
are otherwise hidden or masked by surface noise.
Sonar Appearance Settings
From a sonar view, select Menu > Sonar Setup > Appearance.
Color: Sets the color scheme and color gain.
Overlay Data: Sets the data shown on the sonar screen.
A-Scope: Displays a vertical flasher along the right side of the
screen that shows instantaneously the range to targets along
a scale.
Depth Line: Shows a quick-reference depth line.
Edge: Highlights the strongest signal from the bottom to help
define the hardness or softness of the signal.
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.
