PI Trawl hydrophone

The Simrad PI Trawl Hydrophone is dedicated for bottom and pelagic trawlers.

The Simrad PI Trawl hydrophone is designed to provide the best possible communication with the wireless sensors located on your pelagic or bottom trawls.


You can use one or two hydrophones pointing towards the aft of the vessel, but pay attention to the noise generated by the propellers. Each hydrophone is hull-mounted.

The Trawl hydrophone has a 50 degrees horizontal beam and a 30 degrees vertical beam to provide the catch monitoring system with optimal reception from the sensors on a bottom or pelagic trawl.

This specific beam pattern is especially suited for trawling and the wide coverage area reduces the need for careful alignment.
