ABSTRACT:
1. A device for detecting underwater electrical currents comprising a mem having a cylindrical body portion and electrical conducting end caps secured thereto, an elongated electrical conducting member electrically joining said end caps, toroidal detector coil means inductively coupled to said conducting member for inducing voltage in said coil means by electrical current in said conducting member, annular laminated core means for said coil means for supporting said coil means in encircling relationship to said conducting member, means for concentrating in said conducting member varying magnitude underwater direct electrical currents generated from a vessel by interrupted galvanic action of its propeller and conducted by water means from the vessel to said conducting member, and a firing circuit electrically connected to said coil means for detonating an explosive upon electrical activation of said firing circuit by the induced voltage in said coil means upon concentration in said conducting member of the currents produced by the vessel.
