ABSTRACT:
A solid state depth locator comprises an LCD display having a plurality of LCD segments for providing a real time output indicative of the depth of targets in a body of water. A drive circuit drives each segment of the plurality of LCD segments. A transducer, transmitter and receiver operate together to provide a real time data signal to the drive circuit for driving each segment of the plurality of LCD segments, the real time data signal having a time period and being representative of the presence of targets in the body of water. A clock provides a clock signal to the drive circuit for clocking the real time data signal serially into the LCD drivers. The clock signal has a plurality of clock pulses within the time period of the real time data signal corresponding to the number of LCD segments. A grey scale circuit is provided for varying the intensity of each segment of the LCD display in relation to the strength of the real time data signal.
