The FURUNO CI-68BB is a new Black Box Doppler Sonar Current Indicator designed for various types of fish and hydrographic survey vessels. The CI-68 displays tide speed and direction at three depth layers and ship’s speed on a user-supplied CRT or LCD screen. Using this information, you can predict net shape and plan when to throw your net.

The CI-68BB has a triple-beam emission system for providing highly accurate current measurement. This system greatly reduces the effects of the rolling, pitching and heaving motions, providing a continuous display of tide information. When ground (bottom) reference is not available acoustically in deep water, the CI-68BB can provide true tide current information by receiving position and speed data from a GPS navigator and heading data from the satellite (GPS) compass SC-50/110 or gyrocompass. In addition, navigation information, including position, course and ship’s track, can also be displayed.

The CI-68BB consists of a control unit, processor unit and transducer. The display (user supplied) can be installed separately for flexible installation. A standard configuration (with monitor) is also available. CI-60G users can easily upgrade without drydocking to CI-68 since it uses the same transducer as the CI-60G.
