Furuno Color Video Sounder FCV-291/292 - Manual (Page 3)

NAV DATA
The NAV data screen shows own
ship's position, speed, distance run,
waypoint data with wpt number,
range/bearing to wpt and XTE, water
depth and temperature.
ECHO COLOR
CHANGE
One of any colors among the color bar
can be replaced with white color to
emphasize the specific echo level.
A-SCOPE
The A-Scope picture on the right 1/3 of
the screen shows an instantaneous echo
envelope at each ping, clearly showing
echo differentials and positional
relationship. This is useful for closer
observation of target depth.
CHANGE OF
DISPLAY COLOR
BOTTOM
DISCRIMINATION
Background color can be changed in
the Menu for optimum viewing even
at night time. A monochrome amber
presentation is also available.
DUAL
FREQUENCY
(FCV-292 only)
The bottom is displayed as a straight line.
Echoes immediately below this line will
have enhanced bottom tails. Harder
bottom creates darker and longer tails.
The nature and any changes in bottom
density can be easily determined by any
changes in color or tail lengths.
Dual-frequency operation
assures better resolution
using a high frequency
and deeper range and
penetration using a low
frequency.

Bottom Tails

Bottom fish
The FCV-291 and FCV-292 have an
AUTO mode for hands-off operation.
It automatically acquires and tracks the
seabed, while adjusting receiver
sensitivity for optimum echo presentation.
The stylish display unit allows flexible
installation, fitting nicely on a table top or
overhead location.
