A user worn man overboard beacon that provides multiple indication means to alert a ship to an overboard crew person and to assist in locating the crew person. The beacon device is contained in a housing attached to the clothing of the sailor and is activated upon contact with seawater. A battery powers the multiple indicators contained in the housing, which include a high intensity strobe light to provide a visual indication, an x-band radar patch antenna to transmit a radar signal indication that can be detected by the ship's radar system, and an acoustic transducer to project an acoustic signal indication that can be detected by the ship's sonar system.
