1.2 The Fishfinder Display
When you first turn the display unit on and select fishfinder mode, the
scrolling bottom graph is displayed. This is a graphical representation of the
echoes seen by the Fishfinder. As time passes, this display scrolls from right to
left and becomes a record of the echoes seen. A typical display is shown in
Figure 1-2.
The images at the right hand side of the display are the most recent echoes.
Some echoes indicate fish, and others show the bottom. It can also indicate
bottom structures, such as a reef or shipwreck. The upper and lower depth
range limits are shown.
The fishfinder screen includes a status bar that displays transducer frequency
and indicates which auto settings are enabled (Gain, Color Gain, Range,
Zoom and Frequency), and alarm status (fish and shallow/deep water depths).
You can customize the fishfinder by choosing what is displayed and how it is
displayed (including language and units). For example, you can set the scroll
speed of the bottom graph display, and you can select the range to adjust the
amount of detail displayed.
You can view the cursor position and a variety of data (such as speed, heading
and depth) from the transducer and other equipment in user-selectable data
boxes. These data boxes can be moved around the screen and they can be
switched on or off.
Chapter 3 includes details on adjusting the display, other set up options are
described in Section 7.3 and Section 7.4.
