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 upper left corner and can be changed to
suit conditions. 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. 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.
