Simrad SX90 Basic functionality The basic principles of the Simrad SX90 are unique because of the 256 separate transmitter and receiver channels with their transducer elements spread around on the cylindrical transducer. The transmission, reception and data processing are under...
Simrad SX90 Figure 5 60 degrees vertical slice This vertical slice, which is presented by the white audio line in the horizontal picture, can be selected to any bearing by the manual training control. The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation.
Simrad SX90 Stabilisation system The Simrad SX90 is provided with a stabilisation system. When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees. The beam direction will then change continuously according to the vessel’s movements, and...

The RCG filter must therefore be used with care if scattered schools are to be detected. Ping-to-ping filter Thee Simrad SX90 is equipped with a ping-to-ping filter (PP Filter) to provide a clean and steady presentation by reducing the interference and noise. This filter compares the echoes from a...
Simrad SX90 Transmission The transmission is controlled by the Processor Unit. The parameters you have chosen are used. There are 256 separate transmitters in the unit distributed on eight transceiver circuit boards. Each transmitter is individually addressed and controlled from the signal processor.
Menu system MENU SYSTEM The Simrad SX90 Fish finding sonar comprises a large number of different menus on several levels. Menus are selected by pressing their respective tabs on the right hand side, and the appearance of menus and tabs depends on the chosen operational mode and the current settings.
Simrad SX90 OPERATING PANEL The most frequently used functions are directly accessible by the designated control buttons on the Operating Panel, and may enter operational commands directly. The buttons are grouped in fields according to their purpose. Most sonar functions are also...
Examples EXAMPLES This page presents several screen captures taken from actual operations on fishing vessels. Figure 10 Herring On this screen capture, you can see that the sonar has detected three schools of herring. The skipper has decided to catch the school with highest density, and this is the school closest to the vessel.
