Downlook Page
When you first turn on the display unit, the unit automatically switches to
the Downlook page. Figure 3-3 shows a typical display. (The Downlook
page is also called the “standard” or “chart” or “bottom graph” display.)
As time passes, this display scrolls from right to left. The scrolling image
becomes a record of the echoes and the bottom seen by the Fishfinder
as your boat moves.
The images at the right side of the display show the most recent echoes.
Some of these echoes indicate fish, and others show the bottom. As
new echoes are received, the Fishfinder “draws” a graph of the bottom.
The bottom graph helps you to tell whether the bottom is rising or falling.
It also allows you to identify the shape or “structure” of the bottom. This
can indicate a reef or shipwreck.
