FISH FINDING METHOD AND SYSTEM

摘要

A buoy to shore fish finding system has a buoyant station (18) with a sonar transmitter, a sonar receiver, a sonar to electric signal transducer and a radio transmitter all controlled by a microprocessor. The system shore station (20) has a radio receiver and signal display controlled by a shore station microprocessor. The buoyant station microprocessor is programmed to generate sync pulses and to transmit both the sync pulses and transduced sonar echo returns to the shore station while the shore station microprocessor is programmed to display only echo signals received after a sync pulse. The shore station may be shore-based or detachably secured to the arm of the fisherman or to his fishing rod.
