The Simrad SU90 is the ultimate long range, low frequency fish finding sonar. We made no compromises during the design of this sonar. If high performance is your only criteria when choosing a sonar, this is your natural choice.

If long range, high resolution, narrow beams and high source levels are important criteria for you, the Simrad SU90 is the sonar you need. We made no compromises during the design of this sonar, our goal was to make the ultimate performance sonar.

The SU90 allows you to choose an operational frequency between 20 to 30 kHz (in 1 kHz steps). The cylindrical multi-element transducer allows the omnidirectional sonar beams to be tilted electronically from +10 to –60 degrees. This allows you to automatically track schools of fish, and to observe the whole water volume around the vessel. A stabilizing system is included for electronic pitch and roll compensation.BM019703_002_001_teigenes_storm_1000px_web.jpg

Compared to the Simrad SX90, the number of channels is increased by 50% giving the sonar an even better performance in selectivity and range.

The narrow opening angle (4,9 degrees at 30 kHz) and the increased source level (3 dB) makes the SU90 a very powerful and high resolution low frequency sonar. The narrow beam makes the SU90 even more ideal for searching fish close to the bottom or close to the surface at long ranges. It also provides a far better vertical view with less "bottom climbing" that is seen on sonars with a wider beam.

Great emphasis has been placed on giving the best possible sonar presentations on a high resolution colour display.

The SU90 is equipped with Simrad's celebrated signal processing software. It includes Hyperbolic FM transmissions (also know as "Chirp") to ensure a clutter free picture with very high resolution in range.

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 SU90 contains an advanced frequency modulated filter system (FM).

The SU90 Processor Unit is controlled by the Microsoft® Windows® operating system, which result in a flexible choice of presentation modes for a large range of user applications.

The narrow beams provided by the SU90 sonar give you several advantages. They will increase the sonar's range and resolution, and offer a vertical view with additional details and a clearer picture. The narrow beams will also decrease the noise level.

The Simrad SU90 fish finding sonar can be provided with one of the following hull units. Which hull unit to choose depends on the size of your vessel and the operational requirements.

• Simrad SU92 (standard) lowers the transducer 1.2 meters below the ship's hull. Maximum vessel speed is 21 knots.

• Simrad SU93 lowers the transducer to 1.6 meters below the hull. Maximum vessel speed is 18 knots.

• Simrad SU94 lowers the transducer to 2.1 meters below the hull. Maximum speed with the transducer fully extended is 11 knots. With the transducer placed in its "middle" position, the speed can be increased.

Each hull unit (except SU94) can be supplied with 4.6 or 7 m transducer cable. The SU94 is only supplied with 4.6 m transducer cable.

A. Hand crank for manual hoisting and lowering

B. Transducer cable with plug that connects to the Transceiver Unit

C. Hoist motor

D. Motor Control Unit

E. Transducer shaft

F. Transducer shaft sleeve

G. Mounting flange

H. Installation trunk (not a part of the hull unit)

I. Transducer

When the sonar is switched on, press the Down button on the Operating Panel to lower the transducer into the water. Before the sonar is switched off, press the Up button on the Operating Panel to retract the transducer into the installation trunk for protection. If you forget this, the transducer is hoisted automatically before the sonar is switched off. It is also hoisted automatically if a serious malfunction occurs to the communication between the bridge and the hull unit.

The transducer can also be lowered to any selected middle position. In case of voltage failure, the transducer can be raised or lowered manually by means of a hand crank.
