Furuno's CA82B-35R transducer has a wide bandwidth of 65kHz-110kHz and is usable with the FCV295, FCV292, FCV1150, FCV1100, FCV1200, DFF3, and BBFF3 units. When used with the FCV1100/1200, sensitivity remains high, even if the frequency is shifted +/- 10% to suppress interference. The CA82B-35R may be installed in the tank of the CA88B-10 or CA100B-10R. When retrofitting these or other transducers, the directional pattern and side lobe characteristics of the beam will be different, and therefore the sounder image may differ from previous installations.
Features: • 2kW • Selectable frequency - 65kHz to 110kHz • Beam angle becomes sharper at higher frequencies: 68kHz = 12.5°, 88kHz = 9.6°, 107kHz = 7.7° • 15-meter cable with no connector
