Offering a broad variety of presentation
modes with fast and simple operation
MARKER ZOOM BOTTOM-LOCK
The bottom is displayed as a straight
line on the lower part of the screen,
regardless of bottom contour.
This mode is useful for detection of fish
close to or on the bottom. The portion of water column to be
enlarged can be freely set by the
zoom markers. The zoomed picture
appears on the left half of the screen.
BOTTOM ZOOM
The zoom markers follow the bottom
contour automatically giving us an
expanded view of the area near the
bottom. This is done even under
conditions of changing depth.
The FURUNO FCV-291 (single frequency) and
FCV-292 (dual frequency) are compact, cost-effective
color video sounders
(1, 2 or 3 kW model selectable) for
professional fishermen. The operating frequency can
be selected from 28, 38*, 50, 88 or 200
kHz (two
frequencies selectable for FCV-292) .
They feature a variety of display modes, user-friendly
operation and easy evaluation of seabed conditions.
The echoes are presented on the 10-inch screen in
up to 16 colors. One of the 16 colors can be
displayed in white to emphasize the specific echo
level.
Display modes include: Single (Low-frequency/Hi-
frequency selectable for FCV-291) , Dual (FCV-292) ,
Marker Zoom, Bottom-Lock, Bottom Discrimination,
Bottom Zoom, NAV data and A-scope. The Bottom
Discrimination mode enhances the bottom echo tails
to easily discriminate between soft, rocky or sandy
bottom. This is done by noting the different colors
and lengths of bottom tails. In the Nav data display,
own ship navigation data can be displayed using
appropriate sensors.
*A 38 kHz model is available for the FCV-291 only.
(The transducer should be supplied locally)
