A device for seismic exploration is in the form of a towed streamer. The streamer is easily managed, is very flexible and has a low weight so that it may be towed with moderate tractive forces. The streamer includes a cable with an inner core, one or more layers of insulated conductor pairs and an outer low-friction protective coating. Both the core and the outer low-friction protective layer are of an acoustically substantially inert material of low specific gravity. Seismic signals are obtained series connected gimbal-mounted geophones arranged in strings connected to the cable at positions spaced longitudinally thereof.
