Sonar Zoom View
Sonar Zoom View provides a magnified view of the bottom and structure. The
Sonar Zoom View makes it easier to see separate sonar returns that would
usually be displayed close together, such as those caused by fish suspended
close to the bottom or within structure.
The Zoom Level, or magnification, is displayed in the lower left corner of
the display. Press the + or - ZOOM keys to increase or decrease the
zoom level.
The Zoomed View is displayed on the left side of the screen. As the
depth changes, the zoomed view updates automatically.
The Full Range View is displayed on the right side of the screen. The Full
Range View includes the Zoom Preview Box, which shows where the
zoomed view is in relation to the full range view.
The Upper and Lower Depth Range numbers indicate the high and low
range 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.
