A precision fathometer interface adaptor for interfacing a shallow and a deep water sonar with a computer operated survey system for a 20-line to 16-line data selector is coupled to a multiplexed 16-line data bus. Two sources of bathymetric data are input to the data bus. For 5-bit BCD the four MSD or LSD are selected for input. The output is selected by three operational modes Select Source 1, Select Source 2 or Automatic. The Automatic mode selects the bathymetric data output for the computer according to the water depth. An externally activated timer generates timeevent markers for external devices.
