Abstract
An echo sounding device for searching and exploring the depth of a body of water is provided with a cathode ray tube (CRT) display showing the echo returns. A memory device is provided to store the electrical signal levels of the echo returns while new signal returns are being received to enable presentation of a bar-graph type of display on the CRT.
