Then, the memorized point is marked on the map. For example, when a fish shadow F appears in the fish search image A2, it is used to store the fish search image A2 at that time in association with the ship position P on the map MP at that time. Regarding the setting of the event marks IM1 to IMn, in the present embodiment, the latest image 1 line (event mark corresponding line IL in FIG. 3) when the event marks IM1 to IMn are set is the fish finder image as the ship progresses. When A2 shifts to the left and moves to the center in the width direction of the fish finder image display area 14b, the fish finder image A2 corresponding to the fish finder image display area 14b is stored in the fish finder image memory 18. Further, the position information of the ship position P when the event marks IM1 to IMn are set is stored in the position information memory 19, and the track line L for the fish search image A2 to be stored (associated with each image line). The position information at that time) is also stored. Further, navigation information (ship speed, bearing, water depth, water temperature, etc.) at the time of setting is also associated with and stored in the position information memory 19 at the same time. The set (stored) event marks IM1 to IMn are displayed as marks on the map MP displayed in the plotter image display area 14a.

  Incidentally, as shown in FIG. 6, the setting process flow of the event marks IM1 to IMn in the control circuit 11 determines whether or not the event marks IM1 to IMn have been input in step S1, and if it is determined that there is an input, step S2 Proceed to Next, in step S2, it is determined whether or not the latest image 1 line (event mark corresponding line IL) when the event marks IM1 to IMn are set has reached the center in the width direction of the fish finder image display area 14b. Proceed to S3. Next, in step S3, the position information and voyage information relating to the event marks IM1 to IMn and the fish finder image A2 corresponding to the fish finder image display area 14b at the time of arrival are associated with each other and stored in the memories 18 and 19, respectively. . A plurality (n) of event marks IM1 to IMn can be set as long as the capacity of the fish finder image memory 18 is specified.

  The set event marks IM1 to IMn can be re-displayed later in the fish finder image display area 14b based on a read operation by the operation input unit 17, and a numeric keypad provided in the operation input unit 17 can be used. When the cursor is placed on the event marks IM1 to IMn to be displayed again and selected, for example, a fish finder image A2 for the event mark IM1 is displayed as shown in FIG. At the same time, the plotter image A1 at that time is displayed so that the event mark IM1 becomes the center of the plotter image display area 14a, and the wake line L1 for the event mark IM1 (from the start point to the end point of the fish finder image A2) is displayed. The wake line L1 may be displayed in a different color from the wake line L displayed when the ship is traveling. Further, an information display window A3 is provided in a part of the plotter image A1, and the information display window A3 displays position information of the own ship position P and navigation information (ship speed, direction, water depth, water temperature, etc.) at that time.
