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.
