ABSTRACT:
This disclosure provides a fish finder, which includes a transmission module and a reception module, for outputting an ultrasonic wave underwater, receiving an echo, and outputting a reception signal corresponding to an intensity of the received echo, a control module for generating echo data corresponding to a depth based on the reception signal, a display module for displaying the echo data, and a user interface for receiving a user's operation. The control module causes the display module to display the echo data so that the echo data is displayed in two or more display screens. At least one display screen displays an area having a color different from a background color. A part of the echo data at a depth range corresponding to a height of the area is displayed in the other display screen so as to expand the echo data in a depth direction. The user interface specifies a position and a size of the area via the user's operation.
