In addition to the basic function of the line array sound detector that processes and detects information on the seabed, it is possible to control the coordinates where data is captured from the seabed and the position of the low-frequency sound module by attaching a device that can detect the orientation to which the low-frequency sound module is towed. It is a line array sound detector with a built-in bearing sensor.
