Abstract
A computer system is proposed for finding and displaying the depth and depth related values of an object in an aquatic environment in which and LCD display is subdivided into segments each representing a fraction of the total depth range in which the system is operating as well as a fraction of the transit time for the transmission of pulses within the depth range. Each segment is addressed and activated in response to the presence of a receiver output in the microprocessor for a given number of consecutive time-scans, thus providing a quasi-analog visual display of depth on the array of the segmented scale.
