Abstract
A depth finder utilizing a CPU to control the function of various components including a transducer, receiver, and a liquid crystal display, allowing a user to select between fresh and salt water operational modes as well as between English and metric display units. The CPU is controlled by a keypad and varies the rate at which stored transducer data is transferred from the receiver to the CPU such that the data is always representative of a fixed depth increment in any operational mode.
