The CH-300 has a "Cross Section Scan" function.
It allows you to instantly view the vertical plane in
a specific direction by pressing the "CUSTOM
MODE BUTTON". It is useful for evaluating the
concentration and location of the targeted fish
school as well as for navigation purposes.
The world’s first dual-frequency searchlight sonar CH300 is designed for a wide range of commercial or
sport fishing vessels. Its operating frequency can be
selected from either 60/153 or 85/215 kHz, and
the transducers are incorporated in one soundome.
The high frequency of, 153 and 215 kHz, gives a highly
detailed search near and all around the vessel.
The lower frequency, 60 and 85 kHz, enables longrange searches of over 500 m. With advantages of
both high and low frequency, the CH-300 helps to
search on a rough seabed and to greatly enhance fish
school detection.
A variety of presentation modes are available:
horizontal and vertical scan, echo sounder and
the combination mode displaying horizontal and
vertical scan/historical/plotter presentations. The
combination of horizontal and vertical scan helps
evaluate the distribution of fish schools in both the
horizontal and vertical planes simultaneously.
The CH-300’s unique mix mode uses the frequency
characteristic that “high frequency beams receive
stronger echoes from tiny fish, compared with low
frequency”. By comparing the returned echo intensity
of both frequencies, this mode picks out the echoes of
tiny fish and displays them in discriminative colors.
Other echoes are displayed in the weakest color.
This helps to discriminate tiny fish such as small bait
fish from other fish.
The CH-300 provides two target lock modes to track a
fish echo and stationary position such as a fish shelter
or reef. Target Lock automatically tracks the chosen
fish school. In Position Track, the beam is locked onto
the L/L position specified by the target marker.
Standard package consists of a 10.4" LCD, control,
transceiver and compact hull units. This separated
system configuration provides a flexible and spacesaving installation. A BlackBox configuration (without
monitor) is also available. The hull unit, whose travel
or stroke can be selected at either 250 mm or 400 mm,
will fit any boat where a 190 mm (7.5") internal
diameter hull tube is available. Also, a previously
installed CH-250 can be changed to the CH-300
without dry-docking since both models use the same
size hull unit.
Cross section scan
Even in rough seas, the sonar beam is kept at the
required tilt angle by using ship’s pitch and roll
information. The CH-300 can obtain this information from
a satellite compass (SC-50/110). The motion sensor MS100 or clinometer BS-704 can also be interfaced.

by pitching and
rolling, fails to detect
