知装置。[Claims for Utility Model Registration] Reflected signals caused by detection signals are recorded in one of the two mutually orthogonal directions of the display surface, and the reflected signals are recorded underwater so that these records move over time in the other direction. In an underwater detection device that displays the situation, means for displaying a marker at a predetermined location on the display surface, means for detecting reflected signals from a school of fish or the seabed, and detecting signals reflected from the school of fish or the seabed from the output signal of the detection means. and a display device that performs a display operation based on a signal reflected from a school of fish or a seabed that comes from a detection range corresponding to the displayed marker and is selected by the selection device. An underwater detection device featuring:
