Simrad SX90 Fish finding sonar
In addition to the Omni picture, the vertical slice is especially
useful for visualizing the vertical distribution of a school of
fish. In that way, it is not necessary to go over the target to see
the distribution on the echo sounder, which often results in a
spreading of the school.

Multiple frequency operation

In addition to the standard 26 kHz frequency, you can select any
operational frequency from 20 to 30 kHz in 1 kHz steps.
This is a very useful function when it is necessary to suppress
interference from other sonars.

Stabilisation system

The Simrad SX90 Fish finding sonar is provided with a
stabilisation system.
When the beam stabilizer is activated, both horizontal and
vertical beams will be stabilized electronically for roll and pitch
movements up to ±20 degrees. The beam direction will then
change continuously according to the vessel's movements, and
secure an optimal contact with the targets even in rough seas.
