6 (Lowrance developed the world's first transistorized sportfishing sonar in 1957.) A sonar consists of a transmitter, transducer, receiver anddisplay. In simple terms, here's how it finds the bottom, or the fish: The transmitter emits an electrical impulse, which the transducer con-verts into a sou...
