1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD EQ33 Echosounder and
Fishfinder - a high performance echosounder in a unique slim-line design
with a bright 6” TFT color or monochrome display.
The EQ33 is both an echosounder system with selectable frequency i.e. 50
and 200 kHz, providing an impression of what is to be found in the water
under the vessel, and it is a repeater for navigational data from connected GPS
receiver.
DS33 Dual Station for the EQ33 is available with a 6” bright TFT color
or monochrome display. The main unit and the dual station are identical in
design and operation.
How to use this manual?
It is a good idea if you make yourself familiar with the key functions, menu
structure and rotation of pages (screens) described in chapter 2 before you
start out, and then proceed with section 2.5 Initial start-up. For quick location
of a certain term, please check the “Glossary of terms” and the “Index” at the
back of the manual. Also, “How to get started” further on in this chapter will
give you a quick introduction to some of the features you have access to in
your new echosounder.
The display examples shown in this manual are not always an exact copy of
what you will see on the screen, as the presentation depends on your system
configuration and choices of setup.
How to interpret special marked key symbols etc. in the manual:
+/-
Either the + (plus) or - (minus) key may be applied.

EQ33 Introduction and safety summary
1.2 Safety summary
Precaution: Do not open the equipment, only qualified persons should work
inside the equipment. If the glass in the screen breaks, be careful not to get cut
on the sharp edges of the glass pieces.
Power source, fuse and power cable: Check that the DC power supplied to
the unit is within the range of 10 to 32 volts. Note that the appropriate fuse
must be employed (see the fuse rating in section 9.10 Specifications). Ensure
that the power cord is firmly attached.
Grounding: To reduce electrical interference and risk of electrical shock,
properly ground the unit to the ship’s ground using the ground screw at the
rear of the unit. Good grounding should also be exercised for any equipment
connected to the EQ33.
Quality service personnel: The EQ33 is sealed and does not contain any user
serviceable parts. Opening of the unit will void its warranty. Touching electrical parts inside may cause bodily harm. If the unit is not working properly,
check sections 9.7 Preventive maintenance, 9.8 Repair and service, and 9.9
Troubleshooting. If your EQ33 requires servicing or repair, call your authorized SIMRAD dealer.
Glossary of terms: If you have never used an echosounder before or if you are
unsure of how a term is used in this manual, then turn to Appendix A - Glossary of terms.
Default settings: All user implemented data in the EQ33 can be erased by
making a reset of the unit and thus return to factory default settings.

EQ33 Echosounder operation
Chapter 5-1
5. Echosounder operation
The echosounder function of the EQ33 determines the distance
between its transducer and underwater objects such as fish, lake
bottom or sea bed. It does this by utilizing the fact that an ultrasonic
wave transmitted through water travels at a nearly constant speed
of 1500 meters (4800 feet) per second. When a sound wave strikes
an underwater object such as fish or sea bottom, part of the sound
wave is reflected back toward 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 electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any
reflected signals from intervening objects (such as a fish school)
are received by the transducer and converted back into an electrical signal. It is then amplified in the amplifier section, and finally,
displayed on the screen.
The picture displayed is made up of a series of vertical scan lines
(pings), one for each transmission. Each line represents a ‘snapshot’
of what has occurred beneath the boat. The series of snapshots are
accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are
displayed.
Selecting echosounder displays
The EQ33 provides various types of echosounder displays: standard
echogram, A-scope, bottom expansion (zoom) and VRM expansion. Each display has its special advantages. Select the appropriate
setup for the echosounder display in the presentation “Setup” and
“Echosounder setup” displays, considering current sea area and
target fish.

Depth DS fish - define a specific area below the water surface of
minimum and maximum depth for the fish alarm.
Depth DK alarm min. and max. - set up a depth limit alarm for
depth below keel.
Water profile - choose between SALT and FRESH water. The setting will reflect on the:
Velocity of sound in water: SALT = 1470 meters per second and
FRESH = 1430 meters per second as standard. The standard settings can be even more accurate by slightly increasing the number of
meters in warm waters and decreasing in cold waters.
Time/distance scale - will indicate the elapsed time or distance for
the echo picture. The readout will appear in the upper part of the
echo display. Toggle between time and distance in “Scroll synchronisation”, section 5.9.
Echo sampling - is preset to BOTTOM, which enables auto range
and a view all the way to the bottom. In RANGE the unit will not
wait for a bottom echo, but transmit a new pulse as soon as the
selected range has been reached. This mode will often improve
bottom detection and digital depth readout for vessels moving at
higher speeds. Also, it will enable a more detailed search for fish
in mid water range. Auto range is automatically switched off. The
depth alarm setting will have a higher priority than the selected
depth range.
Demo mode - the echosounder will function as though a transducer
was connected, but all data presented in the display will be simulated.

EQ33 Principles of operation
Chapter 8-1
8.1 Parts of an echosounder
An echosounder is composed of a display screen, processor, and transmitter/
receiver unit which in the case of the EQ33 are housed in one unit.
Connected to this unit by a shielded cable is the transducer, which is mounted
horizontally on the bottom of the hull or on the transom.
The display screen presents in graphic and numerical form the information
the processor is receiving and accumulating from the transducer.
The processor is the “brain” of the echosounder. It is sealed inside the unit
which protects it from harm. The processor is composed of highly sophisticated microprocessor, memory and logic circuitry.
The transmitter/receiver (often called the “transceiver”) section of your
echosounder takes it’s commands from the processor. The processor tells the
transceiver to activate the transmitter. The transmitter sends a high voltage
transmit “ping” to the transducer mounted on the hull. At that point the transmitter’s job is done and the receiver takes over (see fig.1 in section 8.2).
The receiver is also connected to the transducer and amplifies the very small
signals received as echoes from fish and the sea floor which arrive at the
transducer (see fig.2 in section 8.2). The receiver is designed to reject other
signals as much as possible and provide enough amplification to see even relatively small targets at long ranges.
The amplified receiver signals are then send to the processor to be shown on
the display screen.
The transducer can be single or multiple ceramic elements in a rugged housing made from reinforced plastic, bronze or stainless steel. The transducer is
attached horizontally to the bottom of the hull. It is essential that the transducer be mounted properly, as echo transmissions are radiated at aright angles
from the transducer face. Shielded cables connect the transducer with the
echosounder.
Chapter 8-2
EQ33 Principles of operation
8.2 How the echosounder works
When the EQ33 is turned on, the processor begins to
send electrical pulses to the transducer. The ceramic
resonator in the transducer has a special property
which enables it to change dimensions slightly when
a varying voltage is applied.
The voltage is thus converted to mechanical vibrations (sound waves) which are then transmitted down
through the water.
See Fig. 1.
Fig. 1 Transmitted ‘ping’
from the transmitter/receiver.
The sound waves move through the water until they
encounter a change in density, such as a fish or the
bottom. This causes the sound waves to ‘echo’ back
up through the water. When the reflected sound
waves (echoes) hit the transducer, the ceramic disk
vibrates at the same frequency. This generates a
varying voltage which goes back up through the
cable to the receiver.
The EQ33 processes the signals and presents them on
the display screen.
See Fig. 2.
Fig. 2 The up arrow indicates:
Echo returning to the receiver.
The down arrow indicates:
Transmitted pulse.
EQ33 Principles of operation
Chapter 8-3
8.3 Transducer beam width
The transducer mounted to the hull of your vessel serves as both a ‘speaker’
when transmitting, and as a ‘microphone’ when the echosounder is receiving. Similar to the way a flashlight focuses light, most of the sound from your
transducer is focused downwards with a smaller amount going out to the sides.
The amount of focusing of the sound beam is expressed as a ‘beam width’.
Transducer
Approximation of the sound
pattern below the transducer
This angle is the transducer’s
beam width
1/2 maximum intensity
Maximum intensity
Fig. 3 A representation of a transducer beam width.
The center of the sound beam is the most intense, then as you move out
towards the sides of the sound beam there is a point where the intensity of
the sound is half what it was in the center. The distance moved is the ‘beam
width’. See Fig. 3.
Chapter 8-4
EQ33 Principles of operation
8.4 Effects of the vessel’s speed
The presentation of fish on the EQ33 depends directly on the vessel’s speed,
as well as on the depth of the fish. When the vessel is at rest, the echo traces
will appear stretched and flattened. As the vessel’s speed becomes greater, the
echo traces will become shorter and more arched. The reason for this change
in appearance is that as the vessel speed increases, fewer number of sound
‘pings’ strike each fish. A low vessel speed will provide the most accurate
information of where fish are located.

9.6 Basic transducer and cable information
The installation should be carefully planned in advance, keeping in mind the
standard cable length of 10 meters (32 feet) which is connected to the transducer. In the event where the standard cable is not long enough, up to an additional 10 meters (32 feet) may be connected without a noticeable reduction of
the performance. The cable must be of the same type as the standard cable.
The EQ33 must be turned off while connecting/disconnecting the transducer cable.
The use of longer cable runs, while possible, always increases the likelihood of
increased interference and decreased performance. Care must be taken when
increasing the cable lengths to ensure that proper, adequate and consistent
Chapter 9-8
EQ33 Installation and service
shielding is maintained, that cable of adequate cross section is used, and that
all connections are properly made and protected from the effects of the marine
environment.
If possible, running the transducer cable through a grounded conduit will
greatly decrease the likelihood of interference. Likewise, the transducer cable
should be run as far as possible from other electrical cabling. If it is absolutely
necessary to pass close to other cabling, it is best to keep as much distance as
possible, and to make all crossings as close to a right angle as possible.

9.6.2 Determining the position for the transducer
The EQ33 is a sophisticated piece of electronic equipment, but how well it will
perform under actual operating conditions will be largely dependent upon the
location of the transducer and how it has been installed.
Careful consideration, therefore, must be given to selecting the mounting location and on deciding the method of installation that best suits the vessel.
Air bubbles and turbulence caused by the vessel’s movement through the water
will seriously degrade the transducer’s performance. Therefore the transducer
should be located well clear of any water intake or discharge line and also
clear of any projection along the hull line which might disturb the smooth flow
of water. It is of profound importance for good performance of the EQ33 that
the water flowing over the transducer be free of bubbles and aeration. If the
transducer face is clean but the performance degrades with increasing vessel
speed, then aeration of the water flowing under the transducer may be the
cause of the poor performance.
Due to the varying design of ship’s hulls and different operating speeds, there
can be great variation in the amount of air bubbles which are carried beneath
the hull. These bubbles tend to be carried close to the hull as they pass aft. For
this reason, it is desirable for the transducer to be mounted on a fairing block
Chapter 9-12
EQ33 Installation and service
which holds the transducer away from the hull and which directs the flow of
aerated water around the sides of the transducer rather than over the face of
the transducer.
On deep keeled vessels, care must be taken to ensure that the transducer beam
will not be blocked by any part of the keel. Although the appropriate mounting location that meets all requirements depends on the type of vessel and its
normal operating speeds, a practical choice is usually somewhere between one
third and one half of the vessel’s water line length from the bow. Levelling
blocks may be designed accordingly to meet this requirement.
The more the transducer protrudes from the hull, the better the results will
be.
Particularly at lower frequency operation (50kHz), interference from propeller noise can be a significant problem. This can be seen as an increase in the
“noise” on the echosounder display when the propeller speed is increased. To
help reduce this, the transducer’s mounting face may be angled slightly forward on the order of 3-5°. The goal is to incline the transducer so that a line of
sight along the transducer’s radiating surface passes below the propeller.
Keeping the propeller clean and free of any nicks or roughness will assist in
minimizing interference from propeller noise due to cavitation.
Sources of noise to consider:
Water/air
noise
Air bubbles
Turbulence
Propeller
Acoustic noise
Main engine
Reduction gear propeller
shaft
Generators auxiliary
engines
Power plant for freezers
Hydraulic pumps
Rudder engine

9.7 Preventive maintenance
Surface cleaning – to keep the EQ33 cabinet and display screen clean, wipe
the surfaces with a clean damp cloth. For heavier cleaning, use a clean, damp
cloth which has been dipped in a solution of a mild dish detergent and water.
Wring out firmly before wiping the unit.
Never use cleaning solutions containing spirit or alcohol.
Electrical connections – periodically check the electrical connections. Make
sure that connections are tight and that no cables are frayed or worn.
Transducer - periodically clean the face of the transducer with a plastic utensil using a scrubbing action.
Do not use a harsh abrasive or a solvent to clean the transducer.
9.8 Repair and service
The EQ33 is sealed and does not contain any user serviceable parts. Opening
of this unit will void its warranty. If the EQ33 requires servicing or repair, call
your authorized SIMRAD dealer, but first check section 9.9 Troubleshooting.
Spare parts – fuses may be bought from a chandler or a marine supply store.
Use only fuses specified for this unit – see 9.10 Specifications.

EQ33 Glossary of terms
Appendix A-1
Alarms – can be set to sound a “beep” if the echosounder detects a target
above (shallower than) a minimum alarm depth or below (deeper than) a maximum alarm depth. The EQ33 allows you to set the alarm depths and to enable
or disable both the minimum and maximum depth alarms.
A-scope – a method of displaying the echosounder information. In A-Scope
mode, the echoes are displayed in a “bar-graph” format, with stronger echoes
displayed not only in the color representing their target strength, but also in a
width representing their target strength.
Color threshold – the color threshold function allows the “weaker” targets
and noise which may be shown on the display screen to be eliminated from
the display. These targets are usually shown in the weaker target colors such
as blues and greens. The Color threshold allows you to choose not to display
the blues, or the blues and greens, etc. Doing this will leave only the stronger
targets on the display screen.
Configuration – the configuration functions of the EQ33 allow you to adapt
the system more specifically to your needs. You may set Units of measure
(feet, fathoms, meters, etc.), Menu languages, Scroll speed, etc.
Depths – DK = Depth below keel, DS = Depth below surface, DT = Depth
below transducer.
Echogram background color – is the color shown on the EQ33 in the event
no target is present. There are three colors to choose from, white, blue or
black, where black is especially useful during nighttime operation when the
white background could appear too bright.
Echosounder frequency – 50 kHz or 200 kHz can be selected to suit the
task. 200 kHz is for general purpose and offers optimum discrimination and a
narrow transmitter beam. 50 kHz is for searching in a wider area, determining
bottom conditions and going the deepest.
Event marker – allows the user to set a vertical marker on the screen at the
current ping to indicate a school of fish, etc.
Expansion (zoom) – this function allows you to take a closer look at a particular section of the water underneath your boat. You can expand the view
near the bottom (Bottom expansion) or near the Variable Range Marker (VRM
expansion). The amount of expansion can be adjusted in “Expansion window”,
Presentation setup.
Gain – is another way of saying “sensitivity”, or possibly “volume”. Increas-
Appendix A-2
EQ33 Glossary of terms
ing the gain setting of the EQ33 will allow you to see smaller and deeper
targets. If the gain is set too high, however, you will begin to see “noise” and
unwanted targets. Generally speaking, you want to set the gain control just
below the point that you begin to see speckles of “noise” between surface and
the bottom on the screen.
LOG speed calibration – the unit is preset to receive 19000 pulses per nautical mile from the log transducer (paddle wheel). However the figure might
have to be changed to compensate for various transducers and actual water
flow passing the transducer. The correct pulse rate is calculated by:
19000 x indicated speed (e.g. 4kn) = 15.200 pulses/nm
actual speed (GPS) (e.g. 5kn)
Measurement units – the user may select the displayed units to be one of the
following:
m
meters
ft
feet
fm
fathoms
nm
nautical mile, 1 nm is 1,852 meters
kn
knots, nautical mile per hour
km
kilometer, 1 km is 1,000 meters
kh
kilometer per hour
mi
statute mile, 1 mile is 1,609 meters
mh
mile per hour
MENU – the selection of main menus will be shown in the upper part of the
screen. Leaf through the menus by means of the cursor key and the [ENT]
key, or use the numerical keys to activate one of the menus.
NMEA – National Marine Electronics Association. The NMEA is an organization of manufacturers of marine electronics equipment. They have adopted
the NMEA0183 as a standard for communications between various types of
marine electronic equipment.
Ping to ping filter – can be set to either on or off. With the filter “off”, then
each received echo will be reflected on the screen. Whereas with the filter
“ON”, the system will compare every two echoes received and only reflect on
the screen what is received from both echoes, which will give a more uncluttered and precise recording.
Pulse length – the transmitted pulse length can be set to OFF for observing
noise in the water (Auto range will switch to manual mode). Set to AUTO, the
optimum setting will be applied according to the water depth. Or it can be set
manually, if a specific pulse length is required - see next page:
EQ33 Glossary of terms
SHORT
MEDIUM
LONG
Appendix A-3
less than 10m deep water
between 10 and 50 m deep water
more than 50m deep water
A long pulse will reach deeper but give less resolution.
Range – refers to the distance shown from the top to the bottom of the display
screen. Selecting Auto range will cause the EQ33 to change the basic range
setting(s) to keep the displayed bottom in the lower half of the display. For
instance, as your boat moves into deeper waters, the system will automatically
switch to a deeper range, always keeping the displayed bottom in the lower
half of the display. Manual range allows the operator to set the range displayed on the screen.
Range start – allows the user to set the displayed depth range to begin at
some point below the surface. For example, a 100 meter displayed range can
be “phased” downwards, so that the screen shows a 100 meter section beginning at, say, 200 meters and going to 300 meters depth.
Scroll speed – is the rate of movement of the targets on the display screen,
moving from right to left. It is adjustable, to allow the user to show a longer
“history” on the display screen, if desired.
Scroll synchronization – the screen can be updated on the basis of time or
distance (when data from last ping appears on the display).
Signal threshold – can be set to ON to eliminate the appearance of unwanted
noise. The threshold level is automatic and the feature should be used with
caution, as it may eliminate small fish and small unidentified objects on the
screen.
TFT – Thin-Film Transistor (Active matrix) display.
Transducer – the transducer serves as the acoustic “loudspeaker” and “microphone” to send and receive the signals through the water. They are most
often made from ceramic elements carefully built into a robust housing. The
ceramic elements change shape when a voltage is applied across them (when
the EQ33 transmits a signal), and they also generate a voltage when they
encounter sound waves (as when the EQ33 is receiving an echo).
Appendix A-4
EQ33 Glossary of terms
Transmit power – should normally be left on AUTOmatic.
The modes available are: AUTO, 600W, 100W and 10W.
TVG – Time Varying Gain – is a control that allows the EQ33 to make corrections for most of the losses and absorption that occurs as sound energy passes
through sea water. There are three settings to choose from, Normal, Special
and OFF.
The setting “Normal (20 log R) is for general fish finding at depths down to
50m (150’) and it will also give a uniform bottom echo presentation at shallow,
mid and deep water.
The setting “Special (40 log R) will adjust the TVG to show the same echo
strength for a given size fish at varying depths.
The OFF position is used for net sounders. In OFF position the TVG is inactive which means that the sounder operates with a fixed gain between each
transmitter pulse. Auto range is switched to manual.
White line – is a control which places a white/black line at the displayed sea
floor and blanks out 4 pixels just below the line. The purpose of this is to help
the user detect targets, such as fish, which are very close to the sea floor and
whose echoes tend to merge with those of the sea floor itself.
VRM – Variable Range Marker – this refers to a horizontal black line shown
on the display screen. The user can measure the range to targets shown on the
display screen by use of the VRM. The depth to the VRM can be seen in the
left side of the screen. This function is not available if VRM expansion is ON.
XTE – Cross-Track-Error (-Distance), measured magnitude of the position
error perpendicular to the intended track line.
