What’s on the Sonar Display
Understanding the Sonar Display
It
is
important
to
understand
the
significance of the display. The display does
NOT
show
a
literal
3-dimensional
representation of what is under the water.
Each vertical band of data received by the
control head and plotted on the display
represents something that was detected by
a sonar return at a particular time. As both
the boat and the targets (fish) may be
moving, the returns are only showing a
particular segment of time when objects
were detected, not exactly where those
objects are in relation to other objects
shown on the display.
The returned sonar echoes are displayed on the screen. As a new echo is
received, the historical data scrolls left across the display.
Real Time Sonar (RTS™) Window
A
Real Time Sonar (RTS™) Window
appears on the right side of the display
in the Sonar Views. The RTS Window™ always updates at the fastest rate
possible for depth conditions and shows only the returns from the bottom,
structure and fish that are within the transducer beam. The RTS Window™
plots the depth and intensity of a sonar return. (See
Sonar Menu Tab: Real
Time Sonar (RTS™) Window
).
SwitchFire™
SwitchFire™
controls how the sonar returns are displayed in the Sonar
Views. SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam
so more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the
transducer beam, choose Clear Mode. See
Sonar Menu Tab: SwitchFire™
for more information.
The
Narrow RTS Window™
indicates the sonar intensity
through the use of colors.
Red indicates a strong return
and blue indicates a weak
return. The depth of the
sonar return is indicated by
the vertical placement of the
return on the display depth
scale.
The
Wide RTS Window™
indicates the sonar intensity
through the use of a bar
graph. The length of the
plotted return provides an
indication of whether the
return is weak or strong. The
depth of the sonar return is
indicated by the vertical
placement of the return on
the display depth scale.
