Simrad SU90
Long-range 20-30 kHz fish-finding omnidirectional sonar
The Simrad SU90 is the ultimate long-range, low-frequency fish-finding sonar. We made no compromises during the design of this sonar. If high performance is your only criterion when choosing a sonar, this is your natural choice. If long range, high resolution, narrow beams and high source levels are essential criteria for you, the Simrad SU90 is the sonar you need. Our goal was to make the ultimate performance sonar.
Advanced sonar capabilities
The Simrad SU90 allows you to choose an operational frequency between 20 to 30 kHz (in 1 kHz steps). The cylindrical multi-element transducer allows the omnidirectional sonar beams to be tilted electronically from +10 to –60 degrees. This enables you to automatically track schools of fish and observe the whole water volume around the vessel. The stabilizing system included allows for electronic pitch and roll compensation, ensuring precise and reliable tracking of marine life.
Enhanced performance and resolution
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.
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).
"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

System diagram
The Simrad SU90 system units are typically installed on the bridge and in a sonar room. The main communication line between the bridge units and the Transceiver Unit in the sonar room is a high-speed Ethernet cable. The Simrad SU90 fish-finding sonar comprises the following units:
(A) Display (the second display is optional)
(B) Processor Unit (computer)
(C) Operating panel (optional)
(D) Transceiver Unit
(E) Hull Unit
(F) Hoist motor
(G) Motor Control Unit
(H) Transducer

Current software version
We recommend always upgrading your Simrad SU90 system with the latest software version.
Contact your local dealer for an upgrade. They can provide the software update and relevant licenses and will install the software for you. Your dealer can also advise on using and maintaining your sonar system.
Software release 24.7.4 only adds support for the Mk4 Operating Panel. Unless you use this operating panel or plan to replace your existing panel, you do not need to upgrade your system with this new software version.
