System description
The Simrad MF90 is an omnidirectional high frequency fish finding sonar.
The MF90 system is designed for fishing vessels of all sizes, both purse seiners and trawlers.
The centre operational frequency is 80 kHz. You can select any operational frequency from
75 to 85 kHz. The cylindrical multi-element transducer allows the omnidirectional sonar
beams to be tilted electronically. 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.
The MF90 system offers a number of standard interface lines for communication with
peripheral devices and sensors. Typical inputs are geographical information from a
