The Simrad ST90 is a long-range and low-frequency fish-finding sonar with 360 degrees coverage. It is specifically designed for medium and large-sized fishing vessels, offering high performance with characteristics such as long-range capability, high resolution, narrow beams, and high source levels. The ST90 represents a no-compromise approach in sonar technology, aiming to be the ultimate in high-performance fish-finding. Utilizing lower frequencies than the SX90 and SU90 sonars, the ST90 embodies innovative developments made by Simrad in pursuit of unparalleled sonar performance.
If high performance is your number 1 criterion when choosing a sonar, such as long-range, high resolution, narrow beams and high source levels, the Simrad ST90 is your natural choice. We made no compromises during the design of the ST90. With the Simrad ST90, we use lower frequencies than the SX90 and SU90 sonars.
The centre operational frequency is 19 kHz, but you can select any operating frequency from 14 to 24 kHz in steps of 1 kHz. The cylindrical multi-element transducer allows the omnidirectional sonar beams to be tilted electronically from -10 to +84 degrees. These features will enable you to automatically track schools of fish and observe the whole water volume around the vessel.
It is common for sonars to require many pings to build the various views in the echo presentation. These sonars may, for example, need one ping to build the 360-degree omni view and then several other pings to fetch the echoes for the vertical views. On the ST90, all the sonar views in the presentation are built using the echoes from one single ping. This feature dramatically improves the update rate and provides better real-time information.
