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 display.
