Simrad SP70 System description
The Simrad SP70 fish finding sonar is a long range omnidirectional low frequency sonar. It is designed for medium and large sized fishing vessels, both purse seiners and trawlers.
System description
The standard frequency is 26 kHz (triple and multiple frequencies as option), and the beam can be electronically tilted from +10 to -60 degrees (or optional -90 degrees).
Great emphasis has been placed on giving the best possible presentations on a high resolution colour display. The processor unit is controlled by Microsoft's Windows XP® operating system, which result in a flexible choice of display modes for a large range of user applications.
The signal processing and beamforming is performed in a fast digital signal processing system using the full dynamic range of the signals. In addition to the traditional single frequency transceiver system, the Simrad SP70 sonar contains an advanced frequency modulated filter system (FM).
The spherical multi-element transducer allows the omni-directional sonar beam to be tilted electronically in any direction. This allows you to automatically track schools of fish, and to observe the whole water volume around and below the vessel. A stabilization system is included for electronic pitch and roll compensation.
