Sonar Zoom View
Sonar Zoom View
increases the displayed resolution to separate sonar returns that
are very close together, such as those caused by fish suspended close to the bottom
or within structure. In Zoom View, the display is split to show a narrow slice of the
full range view on the right and the zoomed view on the left. The full range view on
the right also contains the Zoom Preview Box that shows what part of the full range
view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in
the full range view.
As the depth changes, the zoomed view updates automatically to display a
magnified image of the bottom. The Zoom Preview Box shows where the zoomed
view is in relation to the full range view. The Zoom Level, or magnification, is
displayed in the lower left corner and can be changed to suit conditions (see
Sonar
X-Press
TM
Menu: Zoom Level
). Upper and Lower Zoom Depth Range numbers indicate
the depth of the water which is being viewed.
Digital depth is displayed in the upper left hand corner. The digital readouts in the
Sonar Zoom View cannot be customized; therefore, information such as water
temperature and voltage are unavailable in the Sonar Zoom View.

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
).
The
Narrow RTS
®
Window
indicates the sonar intensity
through the use of grayscale.
The grayscale used matches
the bottom view grayscale
setting used in the sonar
history window (i.e. Inverse,
StructureID
®
, WhiteLine
®
,
Bottom Black). 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. The
Wide RTS® Window does not
make use of grayscale.
