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 desired direction to help discern fish school density.

• Target graph lets you monitor fish movement.

• Bottom hardness and roughness graph provides intuitive data on bottom composition.

• User programmable display (three types) divides 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 requires a
net sonde or trawl sonar.)

• USB port provided to save data to USB hard disk.

1.16 Picture Advance Speed

The picture advance speed determines how quickly the vertical scan lines run across the
screen. When selecting a picture advance speed, keep in mind that a fast advance speed
will expand the size of the fish school horizontally on the screen and a slow advance speed
will contract it.

FAST SLOW

The advancement speed may be set independent of or synchronized with ship’s speed.

1. Click Settings.

2. Click Echo image.

3. Click ▼ in the Picture advance box. The fractions in the window denote the number of
scan lines produced per transmission. For example, 1/8 means one scan line is
produced every eight transmissions. STOP freezes the display and it is convenient for

Ship’s speed dependent picture advance

With speed data provided by a speed-measuring device, picture advance speed may be set
according to ship’s speed, the ship’s speed dependent mode. As shown in the figure below
the horizontal scale of the display is not influenced by the change of ship’s speed, thus the
speed-dependent picture advance permits judgment of fish school size and abundance at
any speed.

Note: This feature is available with ship’s speed between 2 and 20 kts. If ship’s speed is

above or below those values, the picture is advanced using the upper or lower limit
whichever is closest to the actual ship’s speed.

Fish school shrinks as speed
is increased; expanded
as speed is decreased.

1.18 Alarms

This sounder has four alarms: bottom alarm, bottom fish alarm, water temperature alarm
and vertical temperature alarm. When the bottom echo or fish echo comes into the alarm
range or the water temperature is within or out of the range of the temperature value set,
the equipment generates audio and visual alarms to alert you. If “Alarm” is enabled on the
Status window, the offending is shown in red, in reverse video. To silence the audio alarm,
press any function key. The audio and video alarms will be released anytime the alarm
conditions are violated.

1.18.1 Alarm description

Bottom alarm

The bottom alarm alerts you when the bottom echo enters the alarm area. The audio alarm
sounds and the visual alarm “BOTTOM” appears in red reverse video and flashes when the
bottom alarm is violated.

Fish alarm

The fish alarm alerts you when fish echoes enter into the set alarm range. The audio alarm
sounds and the visual alarm “FISH” appears in red reverse video and flashes when the
bottom alarm is violated. This alarm is useful when targeting a specific fish specie, since
each fish specie is known to inhabit certain depths.

Bottom fish alarm

The bottom-fish alarm sounds when a fish echo is within a predetermined distance from the
bottom. The audio alarm sounds and the visual alarm “BL-FISH” appears in red reverse
video and flashes when the bottom fish alarm is violated.

Temp alarm (requires temperature sensor)

There are two types of temperature alarms: within range and out of range. The audio alarm
sounds and the visual alarm “TEMP” appears in red reverse video and flashes when the
temperature alarm is violated. The temperature alarm may be used to target specific fish
species, as each fish specie is know to inhabit certain temperature ranges.

V-temp alarm (requires net sonde or trawl sonar)

There are two types of v-temp alarms: within range and out of range. The audio alarm
sounds and the visual alarm “V-TEMP” appears in red reverse video and flashes when the
v-temp alarm is violated.

3.8 Target Sphere Calibration Dialog Box

To accurately analyze fish distribution, it is necessary to calibrate target strength using a
calibration sphere. The calibration is done to jibe the target strength (TS) value displayed in
the fish histogram dialog box with the TS of the calibration sphere.

Follow the procedure below to perform the calibration.

1. Suspend a calibration sphere at least 3 m directly below the transducer.

2. Open the fish histogram dialog box.

3. While observing the echo sounder image, adjust the area marker (yellow rectangle) to
place the echo of the calibration sphere within the area marker. (See paragraph 1.12.1
for details.)
Set the marker at the right edge of the screen in order to measure with most recent data.
It is recommended to make the measuring area as small as possible to keep unwanted
echoes out of the measuring area, however the calibration can be performed with any
size measuring area.

4. Note the TS value in the fish histogram dialog box.
There is no problem if the TS value and the TS value of the calibration sphere do not
agree. Ideally, it is desirable if the distribution graph in the fish histogram window shows
only one bar for the calibration sphere, however the calibration can be executed
regardless of distribution.

5. Confirm that the echo from the calibration sphere appears in the area marker in
consecutive scans.

6. Click System on the menu bar.

7. Click Test/Initialization.
