Recognizes individual or multiple fish instantaneously

ACCU-FISH is a revolutionary Fish size assessment function of the FCV-688. 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


Displaying fish marks

The fish mark can be utilized to display on individual fish echoeswhen detected. It helps beginners to identify the fish targets on thedisplay 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 49cm), is a great help for anglers to identify fish targets. Circle and square indentify targets without hiding fish echo.


Displaying fish size or fish depth

Activating the ACCU-FISH from the menu, FCV-688 displays fish size on the individual fish echo.When the
ACCU-FISH is used concurrently with fish marks, it greatly helps anglers to identify fish targets on the display. You may also select and display the target depth instead of fish size, which helps to see how far the fish is from the boat.


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.


Fish Alarm function

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.
