Introduction
FURUNO Electric Company thanks you for considering and pu rchasing the FCV-30 Color
Sounder. We are confident you will discover why the FURUNO name has become
synonymous with quality and reliability.
For over 60 years FURUNO Electric Company has enjoyed an enviable reputation for
quality and reliability throughout the world. This dedication to excellence is furthered by our
extensive global network of agents and dealers .
Your equipment is designed and constructed to meet the rigorou s demands of the marine
environment. However, no machine can perform its intended function unless properly

Thank you for considering and purchasing FURUNO.
Features
The FCV -30 is a high-performance echo sounder designed for fishing as well as
oceanographic research. Its newly developed multi-beam transducer provides
multi-directional and long-range detection. Consisting of a processor unit, control unit,
transceiver unit and transducer, the FCV-30 provides high definition underwater images on
the monitor of your choice.
The main features of the FCV-30 are
• Stabilization compensation in all directions (all directions ±20°) provides stable images in
rough seas.
• Fish distribution and size can easily be found using the fish histogram display.
• Detection in multi-direction or des ired direction to help find density of a school of fish.
• Target graph lets you monitor fis h movement.
• Bottom hardness and roughness graph provides intuitive data on bottom composition.
• User programmable display (three types) divid es the screen in two, three, four or five
displays.
• Various alarms: bottom, bottom fish, fish, temperature, vertical temperature. (Temperature
alarms requires appropriate sensor. The vertical temperature alarm additionally re quires a
net sonde or trawl sonar.)
• USB port provided to save data to USB hard disk.

1.7 Shifting the Display Range
The basic range and range shifting functions used together give you the means to select
the depth you can see on the screen. The bas ic range can be thought of as providing a
"window" into the water column and range shifting as moving the "window" to the desired
depth.

1.7.1 Selecting the display shift mode
The shift feature works automatically or manu ally. Select a method as follows:
1. Click Setting.
2. Click Echo image.
3. Click the list box for Auto range/shift.
4. Select OFF or Auto shift.
OFF: Manually shift the display range.
Auto shift: The display range is automatically shifted to
put the bottom echo within the specified display area (gray lines). For example, if the
depth to the bottom is 350 m and the display range is set for 0 – 100 m, the bottom is
searched automatically and the display range is shifted. (Shift box is inoperative.)
5. Click the OK button.
If you selected Auto shift at step 4, two gray lines appear. To change the display area do the
procedure in section 1.6.1 from step 6. If you selected OFF, go to section 1.7.2.
Note: The basic range is automatically set to 40 meters in auto shift if the basic range is
less than 40 m.

1.8 Adjusting the Gain
The Gain control adjusts the sensitivity of the receiver. Generally, use a higher setting for
deep waters and a lower setting for shallow waters. In any case, adjust the control so that a
slight amount of noise remains on the screen.
CAUTION
Use the proper gain setting.
Incorrect gain may produce wrong depth
indication, possibly resulting in a
dangerous situation.

1.9 Find Depth and Position of a Fish Echo
You may measure the depth to a school of fish or bottom with the horizontal line marker,
called the horizontal VRM (Variable Range Marker). Further, you may measure elapsed
time with the vertical VRM. For example, you can measure how many minutes before the
current time a fish echo appeared.

Measuring depth, elapsed time and position with the VRMs
Measuring depth
1. Roll the trackball to place the pointer on the horizont al VRM. The shape of the pointer
changes to (
).
2. Hold down the left button while rolling the trackball upward or downward to place the
horizontal VRM on the object that you wish to measure the dept h.
3. Read the depth indication on the horizontal VRM.
Measuring elapsed time
1. Roll the trackball to place the pointer on the vertical VRM.
2. Hold down the left button while rolling the trackball leftward or rightward to place the
VRM on the object that you wish to find position.
3. Read the elapsed time and position on the v ertical VRM.
Note 1: The color of the VRMs can be changed. See paragraph 3.5.
Note 2: You may change the location of the depth indication on the horizontal VRM. For
further details see paragraph 3.2.

1.10 Inscribing Lines
You may inscribe vertical lines on the display to mark schools of fish, shoals, etc.
When an echo of interest appears, click Marker line on the menu bar to inscribe a vertical
line on the display. If TIMER is turned on in the Status window, elapsed time is counted from
the moment the mark is inscribed.
Note that color of the marker line can be changed. For details, see paragraph 3.5.
1.11 Fish Size Histogram
The fish size histogram display shows the length of individual fish with in the area measured.
You may show this display as follows:
1. Display the split-beam display. See paragraph 1.5.
2. Click Disp.
3. Click Display Window.
Display window dialog box
4. Click Fish size histogram to show it in blue (ON state).
5. Click the OK button. The fish size histogram appears and measuring begins.
