[Heaving Correction]: When the ship is in rough seas, the bottom echo and the
echoes from fish are not stable, because the distance to the bottom changes. To re-
move this problem, the satellite compass sends pitch and roll data to the fish finder to
adjust the TX and RX beams. This function requires a FURUNO Satellite Compass.
Not applicable to the internal sounder.
[Transmit Rate Auto]: Automatically set the transmit rate according to ship’s speed,
and is inoperative when there is no speed data.
[Transmit Rate Manual]: Change the TX pulse repetition rate in 21 levels (21 is high-
est power.). Use 20 in normal use. Lower the TX rate in shallow waters to prevent the
second reflection echo.
[Sounder Transmit]: Turn on or off the sounder transmission.
Sounder initial setup
[Zero Line Rejection]: Turn the zero line (transmission line) on or off. When turned
on, the transmission line disappears, which allows you to better watch fish echoes
near the surface. The length of the transmission line changes with transducer used
and installation characteristics.
[Transducer Draft]: Set the distance between the transducer and the draft line to
show the distance from the sea surface (Setting range: 0.0 to 99.9 ft).
[Salt Water]: Select [ON] to use this equipment in salt water.
[Fish Finder Source]: Select the sounder used, among DFF1, BBDS1, DFF3, FCV-
1150 or DFF1-UHD.
7. FISH FINDER (SOUNDER)
7-19
[Transducer Setup]: Select the method to setup the transducer, manually or by se-
lecting the model number.
[Manual]: Enter high/low frequencies and TX power.
[Model Number]: Select the type of the transducer connected.
[Transmission Power]: Interference can appear on the screen when the fish finder
on your ship and another ship have the same TX frequency. To prevent this interfer-
ence, lower your TX power and ask the other ship to lower their TX power. (Internal
sounder and external sounder other than DFF1-UHD)
[External KP]: Turn on to sync with external keying pulse. (For external sounder)
[Bottom Level HF (LF)]: The default bottom level setting (0) determines that two
strong echoes received in sequence are bottom echoes. If the depth indication is not
stable in the default setting, adjust the bottom level here. (For Internal, external sound-
er.)
[Gain Offset HF (LF)]: If the gain setting is wrong, or there is a difference in the gain
between the low and high frequencies, you can balance the gain for the two frequen-
cies here. (For internal, external sounder)
[Auto Gain Offset HF (LF)]: If the auto gain offset is wrong, or there is a difference in
the gain between the low and high frequencies, set an offset here to balance auto gain
for the two frequencies. (For internal, external sounder)
[STC HF (LF)]: Delete unnecessary echoes (plankton, air bubbles, etc.) near the sur-
face that hide the fish near the surface. The setting range is 0 to 10, and 0 is off. 10
deletes unnecessary echoes from the surface to approximately 16 ft. Make sure you
do not use more STC than necessary, because you can erase the small echoes near
the surface. (For DFF3, DFF1-UHD)
[Frequency Adjust HF (LF)]: You can adjust the TX frequency of both the low- and
high-frequency transducers. Use this feature when your fish finder and another fish
finder operate on the same frequency, causing interference. Change the frequency of
your transducer by enough percentage points to remove the interference. (For DFF3)
[TX Pulse HF (LF)]: The pulse length is automatically set according to range and
shift.Use a short pulse for better resolution and a long pulse when detection range is
important. To improve resolution on zoom displays, use [Short 1] or [Short 2]. [Short
1) improves the detection resolution, but the detection range is shorter than with [Std]
(pulse length is 1/4 of [Std]). [Short 2] raises the detection resolution, however detec-
tion range is shorter (pulse length is about 1/2 of [Std]) than [Std]. [Std] is the standard
pulse length, and is suitable for general use. [Long] increases the detection range but
lowers the resolution (about 1/2 compared to the [Std] pulse length). (For DFF3)
[Rx Band HF (LF)]: The RX bandwidth is automatically set according to pulse
length.To decrease noise, select [Narrow]. For better resolution, select [Wide]. (For
DFF3)
[Temperature Port]: Select the data source for water temperature. (For DFF3, DFF1-
UHD)
[MJ]: The water temperature data from the water temperature/speed sensor
[Low Frequency]: The low frequency measured water temperature
[High Frequency]: The high frequency measured water temperature

7.15 Interpreting the Display
Zero line
The zero line (transmission line) shows the position of the transducer. The line disap-
pears from the screen when the range is shifted.
Bottom echoes
The strongest echoes are from the bottom, and are normally shown in reddish-brown
or red. The colors and the width change with bottom material, depth, sea condition,
installation, frequency, pulse length and sensitivity.

Bottom contour
The tail from a hard bottom is longer than the tail from a soft bottom, because the hard
bottom reflects more of the ultrasonic pulse. An echo from shallow water gives a stron-
ger reflection than the echo received from deep water. A longer bottom tail appears
on slopes, because of the difference in travel time at both edges of the beam angle.
For the rough bottom, echoes are reflected on many different planes, which displays
echoes in many layers, giving a 3D effect.
Nature of a bottom
The nature of a bottom is known from the intensity and length of the bottom tail. To
find the nature of a bottom, use a long pulse length and normal gain. For the hard and
rough bottom, the bottom echo is reddish-brown with a long tail. For the mud or sand
bottom, the bottom echo has less red and with a short tail. A bottom with a lot of small
particles can give a long tail on the low frequency picture.
Fish volume
The size and density of a school of fish are indicators of the quantity of fish.

Size of a school of fish
Usually the size of fish echoes on the screen is proportional to the actual size of the
school of fish. However, if two fish echoes appear at different depths with the same
size, the school of fish at the shallower depth is larger because the ultrasonic beam
widens as it propagates and a school of fish in deep water is displayed larger.
Density of a school of fish
If two schools appear with the same color at different depths, the one in deeper water
is denser because the ultrasonic wave attenuates as it propagates and the school of
fish in deep water tends to be displayed in a weaker color.
Bottom fish
The echoes from the bottom are stronger than the
bottom fish echoes so that you can distinguish be-
tween them by colors. The bottom echoes are
normally shown in reddish-brown or red, the bot-
tom fish echoes in weaker color.

Plankton
A plankton layer appears as a large amount of
green or blue dots, and is a possible location for
fish. A plankton layer moves down in the day and
up at night.
Current rip
When two ocean currents of different speeds di-
rections and water temperatures meet, a current
rip occurs. A current rip appears on the screen as
shown in the right illustration.
Surface noise
When the sea is rough or the ship moves over a
wake, surface noise can appear at the top of the
screen.
Air bubbles in the water
When the sea is rough or the ship makes a quick
turn, there can be blank spots in the bottom echo
(see the right illustration). These blank spots are
caused by air bubbles which stop the movement
of the sound wave. These air bubbles can occur
with the low frequency ultrasonic waves.
Unstable bottom echo
The bottom echoes can have a saw-tooth appear-
ance. This occurs in heavy weather because pitch-
ing and rolling changes the direction of the
ultrasonic pulses and the vertical motion of the
ship causes the distance to the bottom to change.

False echo
When an ultrasonic pulse is transmitted, some energy leaves from each side of the
beam. This energy has the name “sidelobe”. Echoes from sidelobes show on the
screen as false images like in the illustration shown below.
