Tide speed and direction for the three depth layers are displayed with vectors.
The depth of each layer can be set manually in 1 m intervals. Other information
such as tide differential between the reference and one of the two other layers,
heading and course can also be displayed in large text.
Displays the speed
components for fore-aft

synthesized vector (green
line) intuitively shows drift
direction. The speed
source is selectable on
the menu from ground
tracking or water tracking.
Tide vectors can be
shown on the ship's
track in user
specified intervals.

or seabed at three
directions simultaneously.

Obtain highly accurate water current
measurement using Furuno’s reliable
acoustical technology.
The FURUNO CI-68 is a Doppler Sonar Current
Indicator designed for various types of fish and
hydrographic survey vessels.
The CI-68 displays tide speed and direction at
five depth layers and ship’s speed on a high defi-
nition 10.4” color LCD. Using this information,
you can predict net shape and plan when to
throw your net.
The CI-68 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-68 can provide
true tide current information by receiving position
and speed data from a GPS navigator and head-
ing 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-68 consists of a display unit, processor
unit and transducer. The control unit and display
unit can be installed separately for flexible instal-
lation. A BlackBox configuration (without moni-
tor) is also available. CI-60G users can easily up-
grade without drydocking to CI-68 since it uses
the same transducer as the CI-60G.
