表示装置。 Ultrasonic waves are sent out from a transducer using a transmission pulse signal from a transmitter, the echo from the ocean is received by the transducer, amplified by an amplifier, and converted into a digital echo signal by an A/D converter. In a fish finder that attaches a column address and a row address to this digital echo signal and stores it in an image memory, reads out the digital echo signal from the image memory and displays it on a CRT display, the depth scale displayed on the screen of the CRT is used. A detection range display device for a fish finder, characterized in that detection ranges are displayed side by side.
