Abstract

892,690. Echo-sounding. ATLAS-WERKE A.G. April 12, 1960 [April 14, 1959], No. 13100/60. Drawings to Specification. Class 40(7). Fish shoals are recorded by a ship's echo sounder stylus and an additional stylus over the recording medium records the depth of a towed net, the additional stylus being displaced from the echo sounder stylus by a distance corresponding to the lateral distance of the net from the ship, Figs. 1 and 2 (neither shown). The net depth may be found by a manometric depth gauge or known echo sounding apparatus on the net. Specification 732,608 is referred to.
