Figure 2-27 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.
