Definition The Simrad SC90 is a 360 degree omnidirectional fish finding sonar with an operational range of 50 to 2000 metres, a selectable frequency of 82.5 to 85 kHz in steps of 0.5 kHz, a vertical beam width of 8 degrees, and 480 receiver channels. The cylindrical multi-element transducer allows the omnidirectional sonar beam to be tilted electronically from +10 to -60 degrees in 1 degree steps. The SC90 is equipped with Simrad's signal processing software. It includes linear frequency modulation transmissions (chirp) to ensure a clutter free picture with very high resolution in range, and automatic roll and pitch stabilisation of +/- 20 degrees. The instrument is available with two hull configurations differentiated by how far the transducer can be lowered below the hull and the resulting maximum operational speed. The SC90 can be lowered 1 metre limiting speed to 20 knots and the SC94 can be lowered 2.1 metres limiting speed to 19 knots. The SC90 hull unit can be supplied with a 4.6 or 7 m transducer cable. The SC94 is only supplied with a 4.6 m transducer cable.
