Rules for transducer handling
A transducer must always be handled as a delicate item. Wrongful actions may damage
the transducer beyond repair. A physical blow to the transducer face may easily damage
one or more elements. Observe these transducer handling rules:
•
Do not
activate the transducer when it is out of the water.
•
Do not
handle the transducer roughly, avoid impacts.
•
Do not
expose the transducer to direct sunlight or excessive heat.
•
Do not
damage the outer protective skin on the transducer.
•
Do not
use high pressure water, sand blasting, metal tools or strong solvents to clean
the transducer.
•
Do not
step on the transducer cables.
•
Do not
damage the transducer cables, avoid sharp objects.

System description
The Simrad SC90 is an omnidirectional high frequency fish finding sonar.
The SC90 is designed for fishing vessels of all sizes, both purse seiners and trawlers.
The centre operational frequency is 84 kHz, but you can select any operational frequency
from 82.5 to 85.0 kHz in steps of 0.5 kHz. The cylindrical multi-element transducer
allows the omnidirectional sonar beam to be tilted electronically from +10 to -60° in
1° steps. This allows you to automatically track schools of fish, and to observe the whole
water volume around the vessel. A stabilizing system is included for electronic pitch
and roll compensation.
Great emphasis has been placed on giving the best possible sonar presentations on a
high resolution colour display.
The SC90 is equipped with Simrad’s celebrated signal processing software. It includes
Linear FM transmissions (also know as "Chirp") to ensure a clutter free picture with very
high resolution in range.
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 SC90 contains an advanced frequency modulated
filter system (FM).
The SC90 Processor Unit is controlled by the Microsoft
®
Windows
®
operating system.
This allows for a flexible choice of presentation modes, and for a large range of user
applications.
