Viewing Data Boxes
The cursor data box and a group of up to six data boxes can be
displayed if the information is available on your system.
You
select which data is displayed in the boxes during system set
up as described in
Chapter 4 . The default data box positions are
along the bottom of the display. Each box can be moved to the
desired position on the screen using the context-sensitive cursor.
To switch data boxes on and off as a group you need to go to
Chart mode. Switching the databoxes on/off in Chart mode also
affects their display in Sonar mode and vice-versa. You can switch
them off and on individually using the System Set Up menu, as
described in
Section 4.3 .
Changing the Scroll Speed
The standard fishfinder display is the scrolling bottom image.
This is a graphical representation of the echoes seen by the
sounder. New information appears at the right hand side of the
display and scrolls to the left.
The speed at which the display scrolls is adjustable. As illustrated
in
Figure 5-7 , if you select a faster speed, more detail is displayed
and is useful when you are looking for fish; if you select a slower
speed the information remains on the display for longer.
