2D ZOOM VIEW

2D 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 2D Zoom View, the display is split to show 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 2D Sonar X-Press™ Menu:
Zoom Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the
water which is being viewed.
Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen
in the 2D Sonar Zoom View and a cursor and cursor dialog box will be displayed on the
screen. The cursor can be positioned on the display using the 4-WAY Cursor Control key to
determine the depth of any sonar return. The RTS® Window continues to update in Freeze
Frame. In addition, see the effects of menu setting changes with Instant Image Update.
Pressing EXIT will exit Freeze Frame and the display will start to scroll.
