The Simrad SX90 is a long range
omnidirectional low frequency fishery sonar.
The Simrad SX90
is a low frequency, high-definition; long range fishery sonar using
a high-end maritime computer to process data from the transducer.
User selectable frequencies between 20 and 30 kHz provide longer range
and prevent interference from other vessels.
With the large
data capacity in the signal processor, there are several unique possibilities
for beamforming. Three different vertical beamwidths, single or dual
vertical view and 180° tiltable vertical views are available.
At 30 kHz operating frequency, the vertical beamwidth is only 6,7
In this screen capture, the SX90 sonar has detected Horse
Mackerel close to the bottom. In the vertical view (bottom left corner)
the school is clearly shown very close or even at the bottom. In the
horizontal view the school is easily seen even though it is practically
sitting on the bottom.
The Simrad SX90 is designed for medium
and large sized fishing vessels, preferably for purse seiners, but
it is also well suitable for trawlers. The sonar allows you to choose
an operational frequency between 20 to 30 kHz (in 1 kHz steps), and
the beam can be electronically tilted from +10 to -60 degrees.
sonar offers unique features such as full circle beam stabilization
for easier fish detection in poor weather and 11 different sonar operating
frequencies to avoid interference from other sonars. The long range
and higher definition of the SX90 will improve your catching abilities
and help to make better use of your time at sea.
has been placed on giving the best possible overview in the search
and catch situation. In addition, full screen echo presentation, scalable
windows, off center, zoom and dual operation are standard functions
on all sonar models. You can evaluate one school while tracking two
other targets, giving you full control of schools and net from detection
The signal processing and beamforming is performed
in a fast digital signal processing system using the full dynamic
range of the signals. In addition to the traditional single frequency
transceiver system, the Simrad SX90 Fish finding sonar contains an
advanced frequency modulated filter system (FM).
multi-element transducer allows the omnidirectional sonar beam to
be tilted electronically down to -60 degrees. This allows you to automatically
track schools of fish, and to observe the whole water volume around
the vessel. A stabilization system is included for electronic pitch
and roll compensation.
