SP90 Sonars ”The Simrad Sonar tracked targets other sonars couldn’t see”

Simrad’s new sonars offer short and long range performance using advanced wide band transducer design combined with digital transmitting and receiving technology. Afrequency modulated (FM) transceiver with special filters enhances fish detection and definition under difficult conditions, while extending the detection range.

Clear presentation Great emphasis has been placed on giving the best possible overview in the search and catch situation.The result is several display modes, where the favorites easily can be selected on the new well arranged operating panel. In addition, full screen echo presentation, resizable windows, off center, zoom and dual operation are standard functions on all sonar models.

â–¼ 20kHz 25kHz 30kHz RANGE Multi frequencyfrom 20 to30kHz! Dual beam Beam stabilization
The sound absorption in salt water decreaseswith frequency thereby giving the lower frequency sonar a longer range. Simrad lowfrequency sonars can vary the frequencyfrom 30kHz down to 20kHz. By maintaining the transmitting power and the transducer efficiency, the Simrad sonars have detection ranges longer than others. The combination of the horizontal and vertical beams displays the schoolof fish from above and from the side at the same time. It is not necessary to go over the target to see the verticaldistribution on the echosounder. When the optional beam stabilizer is activated, both the horizontal and verticalbeams will be electronically stabilized forroll and pitch. The full circle beam stays on the target independent of the vesselmovement. This maintains contact withthe target even in rough seas. Full screen presentation Off center presentation ”Two sonars in one”
In full screen presentation, the echo presentation will be extended to cover all the display area. Offset the vessel to any screen position and enlarge the echoes for more detailed information. In the dual mode, each sonar picture can be set up as if you had two different sonars.Individual frequencies, tilt angles, ranges,gain and filters can be used.
