Simrad FS70

The Simrad FS trawl sonar platform combines "the best of two worlds". It communicates with the vessel by means of a third wire system, and with wireless sensors mounted on the trawl by means of hydroacoustic links.

The new Simrad FS70 Trawl sonar provides the "full picture". It uses the well proven and reliable FS third wire system to establish communication between the submerged sonar head located behind the headrope and the vessel. Simultaneously, the submerged unit communicates with a number of PI or FA sensors by means of hydroacoustic links. The unit even includes a 200 kHz echo sounder.

The visual presentation provided to you on the bridge gives you a clear picture of the trawl opening, as well as information from the sensors. This sophisticated solution allows you full control of any type of fishery, and by means of the information you will be able to increase the quality of the catch and your efficiency at sea.


With the Simrad FS70 the rugged Trawl Unit is placed behind the headrope.

The Simrad FS70 Trawl Unit contains the Sonar Head, a 200 kHz Echo sounder, and the communication circuitry required to receive data from the wireless sensors.

Other wireless sensors are then placed on the trawl to suit your requirements. These report their data to the Trawl Unit, or to a PI system on the bridge.

Display Modes

The Simrad FS70 provides you with a clear sonar picture, a high resolution echogram, and easy operation.

Wireless Sensors

The Simrad FS70 Trawl sonar system will communicate Simrad's latest range of PI sensors. However, if you still use the successful FA Catch sensor, it will communicate with those as well.

When you purchase a new Simrad FS70 system, you can choose between two options:
- A 40 kHz system.
- A 70 kHz system

40 kHz FS70 System

The 40 kHz Simrad FS70 system will communicate with the latest range of Simrad's PI Catch sensors. It will also communicate with the other PI sensors operating on the same frequency.

70 kHz FS70 System

The 70 kHz Simrad FS70 will communicate with the "old" FA sensors. It will also communicate with the latest PI Catch sensors, since this particular sensor can be programmed to operate as if it was a 70 kHz FA sensor!

With a 70 kHz system you will however not be able to communicate with the new PI sensors in Simrad's product range.

Current sensor support

With the current software and hardware functionality provided, the FS70 Trawl Unit can communicate with maximum four Catch sensors (PI or FA). Additional sensors will be added in the near future, and the system can then be easily upgraded.

Upgrading the FS70

If you have a lot of FA sensors, you may not wish to throw these over board. You can then purchase a 70 kHz FS70 system, and use your trusted FA sensors until they simply break apart (which may take a while..!). If necessary, you can add PI Catch sensors.
