A towed device comprising two fish, carrying measuring apparatus, which m remain vertically aligned during the measurements. The device includes a carrying cable fastened to a relay fish. The fish carrying the measuring apparatus are fastened to the cable and a plurality of fins are placed over the cable to improve the drag. A diving wing pulls the cable so that the device remains vertical. The device may be used for measuring gradients of physical magnitudes at sea and in particular the vertical gradient of the magnetic field.
