A system for use with a boat to provide underwater sonar images includes a left side scan sonar transducer for transmitting left side scan sonar pulses and for receiving left side scan sonar return signals and a right side scan sonar transducer for transmitting right side scan sonar pulses and for receiving right side scan sonar return signals. The system further includes signal processing circuitry for processing the left and right side scan sonar return signals to produce side scan image data and a digital processor for providing signals to a display based upon the side scan image data to produce a display image on the display showing boat location, a water column between the boat and bottom, and an underwater image comprising at least one of a left side underwater image and a right side underwater image.
