A fishing bobber includes a strike-indicating signal producing transmitter, e.g. a radio transmitter, for transmitting a radio signal to the fisherman when there is a strike on the line. The bobber includes a bobber body adapted to float on a body of water. A fishing line is connected to it during use. The signal transmitter, which may be a lamp, an audible alarm or radio transmitter is supported by and preferably housed within the bobber. Operatively connected to the transmitter are a pair of probes or electrodes for actuating the transmitter. A sensing means is connected to the probes to detect a current passing between them in response to a fish exerting tension on the fishing line to thereby operate the signal transmitter so as to signal the fisherman, e.g. by broadcasting, a radio signal to alert the fisherman when a fish has struck the bait. One preferred form the bobber includes a pair of electrical probes, i.e. electrodes coupled through a sensing circuit for actuating the signal transmitter when submerged in water by a strike on the line so as to permit an electrical circuit to be completed between the probes.
