200/83 kHz Split Sonar View
Split Sonar View displays sonar returns from the 83 kHz wide beam on the left side of the screen
and displays sonar returns from the 200 kHz narrow beam on the right side of the screen. Depth
is always displayed in the upper left hand corner. You can use the Split Sonar View to make side
by side comparisons between the sonar returns from the 83 kHz wide beam and the 200 kHz
narrow beam.
The digital readouts in the Split Sonar View cannot be customized; therefore, information such as
water temperature and voltage are unavailable in the Split Sonar View.

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.
