Abstract

A marine sonar display device comprises a display, a memory element, and a processing element. The processing element is configured to transmit a transmit electronic signal to a frequency steered sonar element that transmits an array of sonar beams into a body of water in a first direction towards the front of the marine vessel forming a first sonar wedge and a second array of sonar beams into a body of water in a second direction directly below the marine vessel forming a second sonar wedge, receive a receive electronic signal from the frequency steered sonar element, generate an array of sonar image slices, identify a gap in an underwater area between the first sonar wedge and the second sonar wedge, and control the display to visually present the array of sonar image slices in near real time and a sonar image slice in the gap.
