Bottom zoom display
The bottom zoom mode expands bottom and
bottom fish on the left-half window. This mode
is useful for tracking bottom contour. When
the bottom depth increases (or decreases),
the display automatically shifts to keep the
bottom echo at the lower part of the screen.
Marker zoom display
The marker zoom mode expands chosen
area of the normal picture to full vertical size
of the screen on the left-half window. You may
specify the portion to expand by operating the
VRM (Variable Range Marker), which you can
shift with S or T. The area between the VRM
and zoom marker is expanded. This mode is
useful for determining the size of fish in the
middle water.
1.4.4 Nav data display
The nav data displays appear on the left 2/3
of the screen. Data other than depth requires
appropriate sensor.
Two nav data displays are available, Nav
Data 1 or Nav Data 2, and you may select
which to use on the [Display] menu. The de-
fault settings are as follows.
NAV1: Two-data display (SPEED (STW),
WIND)
NAV2: Four-data display (DEPTH,
TEMPERATURE, TRIP METER,
ODOMETER)
You can display between two and four items
in a nav data display and select the item and
order to display them. For details, see section
1.20.
