2. HORIZONTAL MODE
Horizontal/history display
The horizontal display appears in the main window; the history display in the sub window.
The length of the picture displayed in the history display is equal to about four full circle
pictures. Thus the history display enables you to observe the history of fish movement and
distribution. It is also useful for detecting bottom fish, reefs and sunken vessels.
The history display cannot be adjusted.
