REAL TIME SONAR (RTS®) WINDOW
A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar
View only. 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: RTS® Window).
BOTTOM PRESENTATION
As the boat moves, the unit charts the changes in depth on the display to create a
profile of the Bottom Contour. The type of bottom can be determined from the return
charted on the display. A Hard Bottom such as compacted sediment or flat rock
appears as a thinner line across the display. A Soft Bottom such as mud or sand
appears as a thicker line across the display. Rocky Bottoms have a broken, random
appearance.
NOTE: A sloping bottom will be represented as a thicker line across the display. Harder
bottoms typically will be displayed with red and softer bottoms typically will be displayed
with blue.
The sonar returns from the bottom, structure and fish can be represented as either
Structure ID® or WhiteLine®. See Sonar Menu: Bottom View for details on how to set
the bottom view.
Structure ID® represents weak returns in blue and strong returns in red.
WhiteLine® highlights the strongest sonar returns in white, resulting in a distinctive
outline. This has the benefit of clearly defining the bottom on the display.
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.
