| Definition | The Simrad SU90 is a 360 degree omnidirectional fish finding echosounder with an operational range of 150 to 4500 metres (standard) or 150 to 8000 metres (optional), and a selectable frequency of 20 to 30 kHz. The SU90 processor unit includes Simrad signal processing software to ensure a clutter free picture with very high resolution in range. The instrument features narrow beams with an opening angle of 4.9 degrees at 30 kHz, automatic roll and pitch stabilisation of +/- 20 degrees and a source level of 3 dB to enable low frequency, high resolution sounding. The instrument is available with three hull configurations differentiated by how far the transducer can be lowered below the hull and the resulting maximum operational speed. The SU92 (standard) can be lowered 1.2 metres limiting speed to 21 knots, the SU93 can be lowered 1.6 metres limiting speed to 16 knots and the SU94 can be lowered 2.1 metres limiting speed to 11 knots. Each hull unit (except the SU94) can be supplied with a 4.6 or 7 m transducer cable. The SU94 is only supplied with a 4.6 m transducer cable. | |
