The load includes sonar operatively coupled via a microprocessor with a radio transmitter that has an upright antenna (28) located in an upper half (11) of the shell. The shell has a keel (15) with an eyelet (18) for tethering a fishing line to the shell. The buoy functions both as a fishing bobber and communications relay station for obtaining and transmitting images of fish swimming beneath the bobber.</p> |
