。[Scope of claim for utility model registration] Detection information that periodically arrives from a fish finder is converted into digital information via a buffer memory,
Capture and store in main memory for displaying one screen,
In the detection display device in which the information stored in the main memory is repeatedly read out and supplied to the cathode ray tube display device, one detection information is displayed as one display line on the cathode ray tube, and the display lines are arranged in chronological order, A delay means to which the read output of the main memory is supplied and delays the read output by one, two, ..., n times (n is an integer of 2 or more) than the time to read the stored information of the adjacent display; and the delay means. a correlation synthesizing means for performing correlation synthesis on a plurality of combinations of each of the delayed outputs and the readout output; 1. A display device for a fish finder, comprising: switching means for supplying a display signal to the device.
