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.
