Simrad CS90
The Simrad CS90 is an omnidirectional broadband fish-finding sonar.
The Simrad CS90 is the first omnidirectional broadband sonar on the market. The world's first composite transducer makes it possible to transmit and receive in a wide frequency range. This makes it possible to achieve high resolution on longer ranges. You can also adjust the operating frequency for better detection, or to avoid a noise source such as another echo sounder or hydroacoustic system.

The CS90 is designed for fishing vessels of all sizes, both purse seiners and trawlers. The centre operational frequency is 85 kHz, but you can select any operational frequency from 70 to 90 kHz in steps of 1 kHz. The cylindrical multi-element transducer permits the omnidirectional sonar beams to be tilted electronically from -10 to +84 degrees. With this functionality you can automatically track schools of fish, even at close range, and observe the whole water volume around the vessel. A stabilizing system is included for electronic pitch and roll compensation.
The CS90 offers the same user interface and operating software as our other sonars, echo sounders and catch monitoring systems. This enables easier and faster training of new users.
Providing several standard interface lines makes communicating with peripheral devices and sensors easy. Typical inputs are geographical information from a positioning system, vessel speed and the vessel's current heading. By default, the sonar uses a built-in motion sensor. An external motion reference unit (MRU) can be connected for improved operational accuracy.
The echo presentations are optimized for multiple displays. Provided that you have connected additional displays to your Processor Unit, you can use the Docking Views function to take any sonar view and place it on a separate display monitor. When you move an echo view to another display monitor, it will automatically be scaled for the best possible result.
It is common for sonars to require many "pings" to build the various views in the echo presentations. We create the echo presentations using the echoes from one single ping. This functionality dramatically improves the update rate and provides better real-time information.
You can record real-time sonar situations. This recording function allows you to replay complete echo sequences. The playback contains the same echo information. You can use it for mission history, training or troubleshooting purposes.
Compared to our previous sonars, we have improved the tracking function. It can now use echo information from both the horizontal and vertical transmissions.
We have placed great emphasis on an intuitive user interface and the best possible sonar presentations on a high-resolution colour monitor.
The sonar offers our celebrated signal processing software. This software includes Hyperbolic FM (HFM) transmissions. This pulse type is also known as "chirp". It ensures a clutter-free picture with a very high range resolution. The signal processing and beamforming are performed in a fast digital signal processing system using the full dynamic range of the echo signals.
