THEORY OF OPERATION
Your Humminbird LCR works on the basic principals of sonar. An electronic signal is generated within the control head of the unit. When coupled to the transducer, this signal is converted to an ultrasonic signal and is transmitted toward the bottom. The speed of the ultrasonic signal traveling through the waters is approximately 4800 feet per second.
The signal travels through the water until it strikes an object or the bottom. At this instant it is reflected back, picked up by the transducer, reconverted to an electronic signal and is recorded on the display of the LCR.
