Simrad SP70 Features and functionality
The Simrad SP90 Fish Finding Sonar provides you with an impressive range of advanced operational features and functions.
Multiple operational frequencies
On any fishing vessel you have numerous sources for noise, such as propellers, generators, engines and other hydroacoustic equipment. With the multiple frequency operation provided by the Simrad SP90, you will still be able to tune your sonar for maximum performance in order to avoid interference from own and other vessels. The multiple frequency operation comes very handy in other situations as well; high and low frequencies have different detection ranges on different conditions and species. On the Simrad SP90 sonar, you can change the operational frequency from 20 to 30 kHz in 1 kHz steps.
When the beam stabilisation is activated, both the horizontal and vertical beams will be electronically stabilised for the vessel's roll and pitch movements. This allows the full circle sonar beam to stay on the target independent of the vessel movements, even in rough seas. You will always maintain a clear picture of the targets.
The combination of the horizontal and vertical beams displays the school of fish from above and from the side at the same time. It is not necessary to go over the target to see the vertical distribution on the echo sounder.
User selectable beam width
Simrad is once again first with new sonar features. With the Simrad SP90 sonar, we introduce user selectable beamwidth. This feature provides improved range and better resolution in the horizontal picture. When you search for fish at long distances you will set the beamwidth to "narrow" for maximum detection range. When you approach the fish you will use shorter range. The sonar can then be set to change beamwidth to "normal" or "wide" automatically, or you can select the appropriate setting manually. The beamwidth is frequency dependant, and you can have beams as narrow as 7.2 degrees.
Full screen presentation
In full screen presentation, the echo presentation will be extended to cover the entire display area. You can also hide the menu if you don't need it.
Off center presentation
Offset the vessel to any screen position and enlarge the echoes for more detailed information. In this example, the menu has been hidden from view.
dual mode presentation
In the dual mode, we provide you with "two sonars in one". Each sonar picture can be set up as if you had two different sonars working simultanously. Individual frequencies, tilt angles, ranges, gain and filters can be used. In this example, the menu has been hidden from view.
In many cases, the sonar on the bridge has several users. Each user has often his or her own favourite settings. On the Simrad SP90 sonar, you can save these settings using your own name, and retrieve them whenever you take charge of the sonar operations. This saves you valuable time as your favourite colours, settings and parameters are only a few "clicks" away.
Store and recall sonar images
All Simrad sonars include a Store/Recall function. You can choose to save either single sonar images or sequences during a normal sonar search. Later, you can easily play the images back on the sonar display if you wish to study the sonar data in more detail.
