A life buoy with a radar responder.

摘要

A life buoy equipped with a radar responder adapted to transmit waves in response to radar waves from a searcher, the life buoy comprising a hull member (5) of a rigid plastic hollow construction, the hull member (5) water-tightly accommodating a receiving antenna (15), a receiver (16), a transmitting antenna (17), a transmitter (18) and a battery (9) in a vertical manner such that the center of gravity (G) is located at a distance from and below the center of buoyancy (F), and the hull member (5) having a downwardly converging shape from under the level of water at least up to the center of buoyancy.
