Abstract: A fishing bobber has a self-contained electrical circuit therein, to provide an audible noise that signals when a fish has pulled sufficiently hard on the line supported by the bobber. The line is supported on the bobber and contacts are closed to complete a circuit to a noise-making buzzer or the like when the bobber is pulled sufficiently. The case of the bobber is preferably provided with a sound outlet so that the noise is not greatly attenuated by the bobber case.
