Features
TheFURUNOFCV-600Lis a dual-frequency
(50 kHz and 200 kHz) color LCD sounder.
Comprised of a display unit and a transducer,
theFCV-600Ldisplaysunderwater conditions
in 16 colors (including background) on a
bright 5.6-inch color TFT (Thin Film Tran-
sistor) LCD.
The main features of the FCV-600L are
• Compact design permits installation where
space is limited.
• Bright 5.6-inch color LCD with tempera-
ture compensated tone and brilliance con-
trol.
• Wide variety of display modes: bottom
lock,dualfrequency, marker zoom, bottom
zoom, nav data and graphic display.
• Automatic function permits unattended
adjustment of range and gain. The range
scale and gain automatically change to dis-
play the bottom in reddish-brown on the
lower half of the screen.
• Navigation data display (requires naviga-
tion data input from external navigator)
provides position, course, speed, depth,
temperatureand waypoint data indications.
• Alarms: Bottom, Fish (bottom-lock, nor-
mal), Temperature (within, over range set).
• A-scope display discriminates bottom fish,
vital for bottom trawler and trap users.
• Waterproof construction permits installa-
tion on open bridge.
• Universal 10.2–31.2 VDC power supply
consuming less than 15 W power.

The FCV-600L determines the distance be-
tween its transducer and underwater objects
such as fish, lake bottom or seabed and dis-
plays the results on its screen. It does this by
utilizingthe fact that an ultrasonic wavetrans-
mitted through water travels at a nearly con-
stant speed of 4800 feet (1500 meters) per
second. When a sound wave strikes an un-
derwater object such as fish or sea bottom,
part of the sound wave is reflected back to-
ward the source. Thus by calculating the time
difference between the transmission of a
sound wave and the reception of the reflected
sound wave, the depth to the object can be
determined.
The entire process begins in the display unit.
Transmitter power is sent to the transducer as
a short pulse of electrical energy. The electri-
cal signal produced by the transmitter is con-
verted into an ultrasonic signal by the
transducer and transmitted into the water.Any
returning signals from intervening objects
(such as a fish school) are received by the
transducerand converted into an electrical sig-
nal. The signals are then amplified in the am-
plifier section, and finally, displayed on the
screen.
The picture displayed is made up of a series
of vertical scan lines, one for each transmis-
sion. Each line represents a snapshot of what
has occurred beneath the boat. Series of snap-
shots are accumulated side by side across the
screen, and the resulting contours of the bot-
tom and fish between the bottom and surface
are displayed.
