Simrad SX90

The Simrad SX90 is a long-range, low-frequency fish-finding sonar. It is specially designed for vessels where long range is criteria No.1.

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 degrees.BM019903_060_001_omnisonar_1000px_web.jpg

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.

The 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 search range and high definition of the SX90 will improve your catching abilities, and help you to make better use of your time at sea.

Great emphasis has been placed on giving the best possible overview in the search and catch situation. Also, full-screen echo presentation, scalable windows, 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 to catch.

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).

The cylindrical 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.
