A microcomputer-based side scanning sonar system is provided. The system uses a personal microcomputer with a custom designed control and data collection circuit card to provide integrated sonar and navigational data to a display. A specialized software program allows navigational data to be collected from any standard navigational device compatible with NMEA 0183 standards and integrated with sonar data. The system allows accurate and repeatable navigation to sonar targets, including return to the target.
