Split-Screen Sonar Views
The split-screen sonar views enable you to view different
combinations of sonar data simultaneously. For example, you
can view traditional sonar and DownVü sonar views in one
screen. You can edit the layout of a split-screen sonar view to
resize the window and rearrange the data.
The scroll rates of the traditional and DownVü sonar views are
synchronized to make the split-screen views easier to read.
Split-Zoom Sonar View
The split-zoom sonar view shows a full-view graph of sonar
readings, and a magnified portion of that graph, on the same
screen.
Split-Frequency Sonar View
In the split-frequency sonar view, one side of the screen shows
a full-view graph of high frequency sonar data, and the other
side of the screen shows a full-view graph of lower frequency
sonar data.
NOTE: The split-frequency sonar view requires the use of a
dual-frequency transducer.
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.
1
From a sonar view, select MENU > Sonar Setup >
Installation > Transducer Type.
2
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.
Calibrating the Compass
Before you can calibrate the compass, the transducer must be
installed far enough away from the trolling motor to avoid
magnetic interference, and deployed in the water. Calibration
must be of sufficient quality to enable the internal compass.
NOTE: Compass calibration is available only for transducers
with an internal compass.
You can begin turning your boat before calibrating, but you must
fully rotate your boat 1.5 times during calibration.

From the LiveVü Forward sonar page, select MENU > Sonar
Setup > Installation.

If necessary, select Use AHRS.

Select Calibrate Compass.

Transducer Installation Settings
From a sonar view, select MENU > Sonar Setup > Installation.
Transmit Rate: Sets the length of time between sonar pings.
Increasing the transmit rate increases the scroll speed, but it
may also increase self-interference.
Reducing the transmit rate increases the spacing between
transmit pulses and can resolve self-interference.
Transmit Power: Reduces transducer ringing near the surface.
A lower transmit power value reduces transducer ringing, but
can also reduce the strength of the returns.
Filter Width: Defines the edges of the target. A shorter filter
more clearly defines the edges of the targets but may allow
more noise. A longer filter creates softer target edges and
may also reduce noise.
Transducer Diagnostics: Shows details about the transducer.
Flip Left/Right: Switches the SideVü view orientation from left
to right.
Install Depth: Sets the depth below the water line where the
Panoptix transducer is mounted. Entering the actual depth at
which the transducer is mounted results in a more accurate
visual presentation of what is in the water.
Flipped: Sets the orientation of the Panoptix sonar view when
the down view transducer is installed with the cables pointing
toward the port side of the boat.
Beam Width: Sets the width of the Panoptix transducer beam.
Narrow beam widths are better for high-speed operation and
rough sea conditions. They also can improve bottom
definition and thermocline definition.
Wider beam widths generate larger arches for fish target
returns, making them ideal for locating fish. Wider beam
widths perform better in deep water. They can generate more
surface noise and reduce bottom signal continuity during
rough sea conditions.
Use AHRS: Enables the internal attitude heading and reference
system (AHRS) sensors to detect the installation angle of the
Panoptix transducer automatically. When this setting is
turned off, you can enter the specific installation angle for the
transducer using the Pitch Angle setting. Many forward view
transducers are installed at a 45-degree angle and down
view transducers are installed at a zero-degree angle.
Creating a Waypoint on the Sonar Screen
Using the Device Keys
1
From a sonar view, use the arrow keys to select a location to
save.
2
Select SELECT.
3
If necessary, edit the waypoint information.
Pausing the Sonar Display
From a sonar view, select MENU > Pause Sonar.
Viewing Sonar History
You can scroll the sonar display to view historical sonar data.
NOTE: Not all transducers save historical sonar data.
1
From a sonar view, select MENU > Pause Sonar.
2
Use the arrow keys.
Customizing the Overlay Numbers
You can customize the data shown on the sonar screen of some
chartplotter models.
NOTE: Not all options are available on all models.
