showing you what is underneath the transducer right now. You
can use the a-scope to identify target returns that may be
missed when the sonar data is quickly scrolling across the
screen, such as when your boat is moving at high speeds. It can
also be helpful for detecting fish that are close to the bottom.
The a-scope above shows fish returns and a soft bottom
return .

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.
2
Select an option.
LiveVü Forward and FrontVü Sonar Menu
From the LiveVü Forward or FrontVü sonar view, select Menu.
Gain: Controls the level of detail and noise shown on the sonar
screen.
If you want to see the highest intensity signal returns on the
screen, you can lower the gain to remove lower intensity
returns and noise. If you want to see all return information,
you can increase the gain to see more information on the
screen. This also increases noise, and can make it more
difficult to recognize actual returns.
Depth Range: Adjusts the range of the depth scale.
Allowing the device to adjust the range automatically keeps
the bottom within the lower portion 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.
Forward Range: Adjusts the range of the forward scale.
