Simrad SU90

The SIMRAD SU90 uses the latest "Winson" software. This unique software platform is common for all Simrad sonars. It allows you to present the various sonar echoes in separate views, which can be placed on separate display monitors. Another great feature of the new software is its ability to "ping" all the beams simultaneously. This increases the ping rate and thus offers a more frequent update of the sonar echoes in the views.

You can set up your SIMRAD SU90 sonar with the Mk2 Sonar Operating Panel. 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 sonar 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.

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.

Compared to the Simrad SX90, the number of channels is increased by 50%, giving the sonar an even better performance in selectivity and range. The narrow opening angle (4.9 degrees at 30 kHz) and the increased source level (3 dB) make the SU90 a powerful, high-resolution, low-frequency sonar. These features are ideal for searching for fish near the bottom or the surface at long ranges and provide a better vertical view with minimized bottom climbing, that other sonars with a wider beam might experience.

Providing several standard interface lines makes communicating with peripheral devices and sensors easy. We prioritize intuitive user interfaces and optimal sonar presentations on high-resolution color monitors. Celebrated features such as Hyperbolic FM (HFM) transmissions, also known as 'chirp', ensure a clutter-free picture with high range resolution. The signal processing and beamforming are carried out swiftly and effectively in a digital system to present clear and easily comprehensive sonar data.
