1. OPERATIONAL OVERVIEW

Mix display

The mix display compares echo intensity between low and high frequencies, and
displays echoes from tiny fish in discriminative colors. This is done by utilizing
the fact that tiny fish return a stronger echo against a high frequency rather than
a low frequency. This is done as below.

1. If a high frequency echo is stronger than the corresponding echo on the low
frequency, the high frequency echo is displayed.

2. If the low frequency echo is stronger than or equal to the high frequency echo,
it is less likely to be a tiny fish and therefore is displayed in blue.

3. If the echoes on both frequencies have the intensity corresponding to
reddish-brown or red, they are displayed in reddish-brown or red: this is
necessary to display the zero line and bottom in reddish-brown or red.

4. In other words, the echoes displayed in orange thru light-blue may be
considered to be tiny fish such as whitebait.

1. OPERATIONAL OVERVIEW

Ship’s speed dependent mode

With speed data provided by a speed log, current indicator or navigation
equipment, the display 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. The picture advance speed indication is suffixed with
an “S” when the ship’s speed dependent mode is active. For example, “1/1S.”
This function is available with ship’s speed of 2-20 kt. You can use the ship’s
speed dependent mode by setting PRR LEVEL to “S” on the TX/RX menu. For
further details, see PRR LEVEL on page 2-8.

PRR LEVEL

Changes pulse repetition rate. Normally, the highest rate (20) is used. When in
shallow waters, second reflection echoes may appear between surface and
actual bottom echo. In t his case lower the PRR level. The option “S” means the
ship’s speed dependent mode, where the PRR changes automatically with ship’s
speed. (Requires speed input.) For further information about the ship’s speed
dependent mode, see page 1-19.

Note: When using the t ransducer pair 88F-126H and 28F-24H with the PRR

setting of 20, transmitter power will drop slightly on the LF/HF display
when the range is within 40 m.

2. MENU OPERATION

STC (High and Low Frequencies)

Adjusts STC level for the high and low frequencies, and is useful for suppressing
surface noise. The setting range is 0 (OFF) to 10. “10” suppresses noise which
is up to 5 m distance from the face of the transducer. Turn off the STC when
there is no noise on the screen, otherwise weak echoes may be missed.

GAIN ADJ (High and Low Frequencies)

Adjusts gain of receiver unit chosen. Adjust the setting when the GAIN control
cannot effectively adjust the gain.

RX BAND (High and Low Frequencies)

Sets amplifier bandwidth of high and low frequency Rx amplifier. When
NARROW is chosen, the noise suppression is greater however resolution in
shallow water is lower. Normally, set to STD. For increased resolution, choose
WIDE.

TX PULSE (High and Low Frequencies)

Sets TX pulselength for high and low frequencies. The available choices are
SHORT1, SHORT2, STD, LONG, and MANUAL. Pulselengths except MANUAL
automatically change with range and shift .

PULSE LENGTH (High and Low Frequencies)

Sets pulselength, and is effective when TX PULSE setting is MANUAL. Choose
a low value for better detection resolution: a hig h value to increase detection
range.

The zero line represents the transducer’s position. It moves off the screen when
a shifted range is used, or is shown at draft depth when ship’s draft is entered.

4.3 Bottom Echoes

Bottom echoes are normally strongest and displayed in reddish-brown or red,
but colors and width will vary with bottom material, depth, sea condition,
installation, frequency, pulselength and sensitivity.

A hard and rough bottom appears with a longer tail because it reflects more of
the ultrasonic pulse. Because of their stronger return, shallow echoes appear
wider than deep ones even when all bottom conditions are equal. Also, a longer
bottom tail appears on slopes because of the difference in traveling time at both
edges of the beam angle. In the rugged bottom, echoes are reflected on many
different planes, overlapping to present a 3D effect.

Color difference

Second bottom

Rugged

4-2

Bottom material and bottom profile

4. INTERPRETING THE DISPLAY

The nature of the bottom is known from the intensity and length of the bottom tail.
Generally, when observing the bottom nature, the lower sounding frequency is
used, the pulselength is set to long, and the gain setting is not disturbed. In the
hard and craggy bottom, the bottom appears more reddish and with a long tail.
However, the bottom with sediment may give a short tail if a low frequency
sounding is used.

4.4 Fish School Echoes

Fish quantity can be estimated to a certain extent from fish echoes on the screen
if fish school size and fish school density are kept in mind.

Usually the size of fish echoes on the screen is proportional to the actual size of
the fish school. However, if two fish echoes appear at different depths with the
same size, the fish school at shallower depth is smaller because the ultrasonic
beam widens as it propagates and a fish school in deep water is displayed
larger.

4. INTERPRETING THE DISPLAY

If two fish 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 fish school in deep water tends to be displayed in a weaker color.

4.5.3 Surface noise

When the sea is rough or the ship passes over a wake, surface noise may
appear at the top of the screen. It can be suppressed with the CLUTTER
function.

Surface Noise

4.5.4 Aerated water

When the sea is rough or the ship makes a quick turn, gaps in the bottom echo
on the screen may appear. This is caused by air bubbles which block
propagation of the sound wave. Generally low frequency ultrasonic waves are
interrupted more easily than high ones.

4. INTERPRETING THE DISPLAY

4.5.5 False image

Every time the ultrasonic pulse is transmitted, some radiation escapes on each
