Simrad SX90

Long-range 20-30 kHz fish-finding omnidirectional sonar

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 long-range omnidirectional low-frequency sonar. The SX90 is designed for medium and large-sized fishing vessels. It was originally developed for purse seiners, but experience has proven that it is also well-suitable for trawlers.

Versatile sonar system for fishing vessels of all sizes

The Simrad SX90 is a versatile sonar system tailored for fishing vessels of all sizes, including both purse seiners and trawlers. Its central operational frequency is set at 26 kHz, with the flexibility to select any frequency between 20 to 30 kHz in 1 kHz increments. This system is equipped with a cylindrical multi-element transducer, enabling the omnidirectional sonar beams to be electronically tilted from -10 to +60° in 1° steps. Such functionality is crucial for automatically tracking fish schools and observing the entire water volume around the vessel. Additionally, the SX90 incorporates a stabilizing system for electronic pitch and roll compensation, enhancing its operational effectiveness.

"Winson" operating software

This sonar uses the latest "Winson" operating software. This unique software platform is common for all Simrad sonars. It allows you to present the various sonar echoes in separate views, which you can move to separate display monitors. Another great feature of the new software is its ability to "ping" all the beams simultaneously. Multiple pings increase the ping rate and thus offer a more frequent update of the sonar echoes in the views.

Other standard features of the "Winson" operating software are:

  • User interface in more than 20 languages
  • Intuitive access to all operating parameters
  • Save and recall your favourite user settings
  • Save and replay sonar images and video sequences
  • Target and position tracking

Seamless communication with other vessel sensors

The sonar system provides several standard interface lines. These interfaces ensure seamless communication with peripheral devices and sensors, with typical inputs like geographical information, vessel speed, and heading. The built-in motion sensor enhances operational accuracy, and you can increase this accuracy by adding an external motion reference unit (MRU).

Sonar operating panel

This sonar supports the optional Operating Panel Mk.2. This operating panel uses a handy multifunction joystick. The joystick facilitates tilt, vertical, and inspection beam control through simple pushes or twists of the knob. The operating panel communicates with the Processor Unit using an Ethernet connection. This communication format allows for advanced functionality. You can manage up to four different Simrad sonars using a single panel. Conversely, up to three panels in various locations on the vessel can operate a single sonar. The USB port on the operating panel also provides convenient software upgrades and user settings management. The operating panel also features dedicated and customizable buttons and knobs, and its design allows for a straightforward upgrade from older panels using a mounting bracket.
