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.
