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™ 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.

Inverse is a method where weak returns are shown with
dark pixels and strong returns with lighter pixels. This has
the benefit of ensuring that weak signals will be clearly
visible on the display.
Structure ID® represents weak returns as light pixels and
strong returns as dark pixels. This has the benefit of ensuring
that strong returns will be clearly visible on the display.
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.
Bottom Black displays all pixels below the bottom contour as
black, regardless of signal strength. This has the benefit of
providing a high contrast between the bottom and other
sonar returns on the display. Any targets such as fish,
structure and thermoclines will be shown using the
Structure ID® method.
