を特徴とする魚群探知機。[Scope of claim for utility model registration] Emitting ultrasonic pulses from a transducer,
The reflected wave is received as a detection signal, and the detection signal is displayed as a single display line on a scanning display.
In a fish finder in which the display line is sequentially shifted in the direction of the old display each time an ultrasonic pulse is emitted, and a depth scale is displayed along the display line, the above transducer transmits and receives ultrasonic waves diagonally to the vertical direction. A fish finder, wherein the depth scale displays depth in a vertical direction.
