  • Bottom Discrimination Function
    The FCV-587’s Bottom Discrimination feature enables the fish finder to indicate if the major component of the bottom is rocks, gravel, sand, mud.
    The Bottom Discrimination feature provides you with valuable information to locate rich fishing grounds, while boosting your catch of the day.

    Graphic mode
    The standard graphic display mode shows the most probable bottom composition by graphic or four colors.

    Probability mode
    The probability display mode shows the most probable bottom composition in graph form.

    Please keep the following in mind when using the Bottom Discrimination Sounder:

    1) Use at a depth of 5 m - 100 m.
    2) Use transducer in transom mount or thru-hull mount.
    3) Set the transducer parallel to the bottom of the craft.
    4) To show a consistent display of the actual bottom, set the range display of the fish finder screen to “auto”.
    5) Enter the ship’s draft value.
    6) Use a ship speed of 10 kn or less.
    7) In some instances, bottom component indicated on the FCV-587 may differ from its actual bottom structure.
        Please read the operation manual carefully before using this feature.
  • ACCU-FISH™ identifies individual fish with size and fish mark function
    Recognizes individual or multiple fish instantaneously
    ACCU-FISH™ is a revolutionary fish size assessment function of the FCV-587.
    In order to assess individual fish size, the echo strength from the fish needs to be computed and turned into fish size display on the screen. It can detect the fish size of 10 to 199 cm, in the depth of 2 to 100 m.

    Circles and fish size are displayed on fish echoes. When in dual frequencies mode, you can set the mark displayed on both or either frequency screen.
  • Displaying fish marks
    The fish mark can be utilized to display on individual fish echoes when detected. It helps beginners to identify the fish targets on the display for a more fun fishing experience. Fish mark is selectable from two types of fish symbol, circle and square. The fish symbol, displayed in two different sizes (Large: over 50 cm, Small: 10 to 49 cm), is a great help for anglers to identify fish targets. Circle and square indentify targets without hiding fish echo.
  • White Line function distinguishes fish from bottom
    The white line function helps you distinguish bottom fish from the bottom by changing the strongest signal color to white. This function is not only useful discriminating bottom fish but is also valuable for judging fish school density. The setting range is 0%-100%, in intervals of 1%. The higher the value the thicker the line.



  • Configurable Alarm function (depth, fish echoes, etc.)
    When fish echoes come in the area which you set above the bottom, beeps sound and the alarm icon flashes at the top right corner of the screen. Furthermore, an integrated alarm setting is also available that can be set by every and each condition, including water depth, target depth, water temp, bottom component, etc.
  • Post-Processing Gain Control
    With conventional gain controls, changes are made for new echoes only when a change in the gain setting is applied. With the FCV-587’s Post-Processing Gain Control, changes in the gain setting are applied to new echoes as well as all of the echoes already on the screen. Because the changes are applied to both new and existing returns, you will be able to quickly and easily find the right gain setting for your conditions.
