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.)

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)

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.
