The FCV30BB is a high-performance
echo sounder designed for fishing as well as oceanographic research
vessels. This echo sounder employs a new multi beam transducer that
facilitates multi directional and long-range detection. FURUNO?s
leading-edge signal processing technology makes the FCV30BB,
unparalleled in this class of sounders.
The FCV30BB provides a variety of presentation modes: Multi beam,
Split beam, Zoom, and A-scope. Also, images from external sounders or
net sondes can be displayed. Multi mode allows the detection in up to
five directions simultaneously.
The direction and tilt of each beam can be determined by the menu
setting. The directions of the beams can be set anywhere around the
vessel, and the tilts can be set within ? 20 degrees from directly
underneath the vessel. By conducting the searches at five different
directions at the same time, the location and distribution of the fish
school around the vessel is indicated. This also helps understand the
bottom composition, undulation and slant, allowing the operator to make
an accurate judgment of speed and course to trawl.
The FCV30BB has a unique function called ?fish size display? which
measures individual fish sizes within a fish school and display them in
the diagram. The individual fish sizes are computed according to the
echo strength within the section, which can be manually set on the
screen. The fish sizes can be displayed in a diagram by the centimeter.
The FCV30BB is a Black Box configuration, consisting of a control,
processor, transceiver units and a transducer. The control unit consists
only of a trackball, thumbwheel and several soft keys. The Furuno LCD
monitors MU201C (20.1'', SXGA), MU155C (15.1'', XGA) or a PC monitor can
be utilized as a display unit.
With an optional built-in motion sensor, beam stabilizer can be
facilitated, which eliminates the loss of important targets due to
ship?s motion in rough seas. Beams are maintained at required bearing
and tilt by compensating for ship?s pitching and rolling.
The Furuno Satellite Compass SC50 or SC110 detect ship?s heaving as
well as pitching/rolling. The satellite compass improves the echo
presentation by compensating for echoes? ruffling arising from ship?s
heaving. This gives an unwavering presentation of the echo images even
in rough seas, and enhances the accuracy of the measurement for fish
