The FCV-30 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 FCV-30 unparalleled in this class of sounders.
The FCV-30 provides a variety of presentation modes in high resolution SXGA or commonly used XGA resolution:Multibeam, Split-beam, Zoom, and A-scope. Also, images from external sounders or net sondes can be displayed. Multi-beam mode allows transmitting 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.
In the Split-beam mode, the FCV-30 has a unique function called æfish size assessment displayÆ 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 FCV-30 is in BlackBox configuration, consisting of a control, processor, transceiver units and a transducer. The control unit consists only of a trackball, wheel and several soft keys, which makes its operation stress-free. Commercial grade FURUNO LCD MU-201C (20.1', SXGA), MU-151C (15.1', XGA) or a commercial monitor can be utlized as a display unit.
The transducer employs highly sensitive transducer elements to achieve efficient energy conversion, which ensures the detection with minimal output power of 4 kW. Its narrow beamwidth (7¦) enables the detection of the shapes of fish schools and fish distribution in minute detail.
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. FURUNO GPS satellite compass SC-50/110 detect ship's heaving as well as pitching/rolling. The satellite compass improves the echo presentation by compensating for echoes' ruffling caused by 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 size assessment display.
