Introduction
FURUNO Electric Company thanks you for considering and purchasing the FCV-30 Color
Sounder. We are confident you will discover why the FURUNO name has become
synonymous with quality and reliability.
For over 50 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 rigorous demands of the marine
environment. However, no machine can perform its intended function unless properly
installed and maintained. Please carefully read and follow the operation and maintenance
procedures set forth in this manual.
We would appreciate feedback from you, the end-user, about whether we are achieving our
purposes.
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 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.

Note: Normally, pulses are fired from beam 1, beam 2 and beam 3 in that order and
displayed on the screen as the port, downward and starboard images. When the
display range of the 3-beam display is higher than 1000 m, the menu bar shows
“Simul. TX”. To fire pulses from beam 1 – 3 simultaneously click the Simul TX
indication to show ON. When this is done the picture advance speed quickens.
However, the display becomes susceptible to unwanted echoes. The default Simul
TX detection range is 1000 m. This value can be set between 100 and 5000 m. For

Measuring depth
1. Roll the trackball to place the pointer on the horizontal 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 depth.
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
