ABSTRACT:
A signal device for indicating, by day or by night, the location of a person adrift on the surface of a body of water, consisting of a vividly colored inflatable tube made of thin, flexible but nearly inextensible material, provided with a one-way valve for inflation by mouth, and a miniature electric lamp coupled to a water-activated battery. The tube is permanently attached to a life jacket or other garment and has a flag secured to its free end. The tube or the flag or both contain a metallic pigment or are covered with a layer of such material so as to be radar detectable.
