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.
By providing a number of standard interface lines, it is easy to comunicate with peripheral devices and sensors. Typical inputs are geographical information from a positioning system, vessel speed and current heading. By default, the sonar uses a built-in motion sensor. For improved operational accuracy, an external motion reference unit (MRU) can be connected.
The echo presentations are optimized for multiple displays.
