Abstract : The patent describes a passive sonar array mounting and recovery apparatus comprising a frame that is mounted on a plurality of legs. A net is stretched across the interior region of the frame and is held in place with twine. Centrally located and extending vertically upward from the frame is a center post. A plurality of grapnel rods have their ends attached to the upper end of the center post and the other ends attached to the periphery of the frame. The grapnel rods are uniformly spaced apart and extended outward and downwardly from the top of the centerpost to the frame. At the corners of the frame are vertically extending transducer support members. Two transducers are respectively supported by a horizontal tower and a vertical tower that are attached to and extend outwardly from the frame.
