A device for controlling a seismic cable that is towed behind a vessel (1), so that the cable follows a path that is displaced laterally in relation to the path of the vessel, comprises a frame structure (6, 7) extending transversely to the towing direction and outwardly from the area of gun suspension from the cable having longitudinal frame members provided with intermediate transverse members extending obliquely or in a curved manner whereby the front ends of the transverse members, as seen in the towing direction, are disposed further outwards laterally than the rear ends of the transverse members. When towed, the frame will this be forced outwardly by the water flowing through the frame structure and the desired lateral displacement will be achieved.
