A SUBMARINE DETECTOR devised by the late Vladimir S. Goloviznin, of New York City, employs electro-chemical action to give warning of enemy undersea craft operating near the coast. Detector units, anchored in shallow water offshore, consist of pairs of hollow spheres of dissimilar materials which generate an electric current when in contact in salt water. The vibrations produced in the water by a passing submarine cause current fluctuations which are recorded on instruments ashore.
