“ACCU-FISH” identies individual sh
with size and sh mark function
Recognizes individual or multiple sh instantaneously
ACCU-FISH is a revolutionary sh size assessment function of the FCV-627. In order to assess
individual sh size, the echo strength from the sh needs to be computed and turned into sh
size display on the screen. It can detect the sh size of 10 to 199 cm, in the depth of 2 to 100 m.
Displaying sh size or sh depth
Activating the ACCU-FISH from the menu, FCV-627 displays sh size on the individual sh echo.
When the ACCU-FISH is used concurrently with sh marks, it greatly helps anglers to identify
sh targets on the display. You may also select and display the target depth instead of sh size,
which helps to see how far the sh is from the boat.
Displaying sh marks
The sh mark can be utilized to display on individual sh echoes when detected.
It helps beginners to identify the sh targets on the display for a more fun shing experience.
Fish mark is selectable from two types of sh symbol,
circle and square. The sh symbol, displayed in two
different sizes (Large: over 50 cm, Small: 10 to 49 cm),
is a great help for anglers to identify sh targets. Circle
and square indentify targets without hiding sh echo.

can set the mark displayed on both or either
frequency screen.
Bottom Discrimination feature
The FCV-627’s Bottom Discrimination feature enables the sh nder to indicate if a major
component of the bottom is mud, sand, gravel or rocks.
The Bottom Discrimination Function provides you with valuable information to locate rich shing
grounds, while boosting your catch of the day.
White Line function distinguishes sh from bottom
The white line function helps you distinguish bottom sh from the bottom by changing the strongest
signal color to white. This function is not only useful discriminating bottom sh but is also valuable
for judging sh school density. The setting range is 0%-100%,
in intervals of 1%. The higher the value the thicker the line.
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) To show a consistent display of the actual bottom, set the range display
of the sh nder screen to “auto”.
4) Enter the ship’s draft value
5) Use a ship speed of 10 kn or less.
6)
In some instances, bottom component indicated on the FCV-627 may
carefully

Post-Processing Gain Control
With conventional gain controls, changes are made for new
echoes only when a change in the setting is applied. With the
FCV-627’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 nd the right gain setting for your conditions.
Fish Alarm function
When sh echoes come in the area which you set above the bottom, beeps sound and the alarm icon ashes
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.
