Operator Manual
Introduction
1. Introduction
1.1 Purpose of this Operator Manual
This Operator Manual contains instructions and information on the operation of the software package
supplied with your WMB-X230 (i.e. WMB-3230 or WMB-5230) system. Installation and Commissioning
procedures are contained within the Installation Manual, also supplied alongside this manual.
Please refer to the Installation Manual for instructions on transducer and BTxR installation, sensor
connection, system configuration and setup, and commissioning steps required to get your WASSP
system up and running.
1.2 Introducing the WASSP Sonar System
The WMB-X230 is a multi-beam sonar system that uses a wide-angle sonar transducer to profile
the water column and seafloor to a high resolution. It is this unique combination of multi-beam
sonar and processing power which provides you with unparalleled information about the underwater
environment. It gives you a wide 120° port-starboard swath of the water column and seafloor, allowing
you to find and position reefs and wrecks, fish schools, seafloor hardness changes, and foreign objects
in the water column or on the seafloor. From the 120° swath, the system processes 112 dynamic
beams, with each beam containing detections from the water column and seafloor.
The information is presented in a user-friendly, mouse controlled, Windows-based operating system.
The intuitive graphical user interface displays both acoustic views and charting views for complete
knowledge of the world beneath with the ability to view both real-time and previously recorded maps
from any part of the globe in 2D and 3D. Depth and backscatter colours can be dynamically changed
while viewing. The system can output data to plotting software packages. For optimal performance,
roll, heave, pitch, heading and position inputs are all required.
The WMB-X230 can be applied to a variety of fishing methods, as well as search and rescue, customs,
and police applications.
1.3 Main Features
The WMB-X230 has the following main features:
► Improved performance.
The use of separate transmit and receive arrays has enabled WASSP to optimise both transmit
performance and receive sensitivity, giving improved performance over traditional sonar and
sounders.
► High detail picture of marine environment.
The transmit beam spreads over a 120° port-starboard swath and covers 4° fore-aft while the receive
beam covers 10° fore-aft, displaying a highly detailed picture of the marine environment.
► Real-time map generation.
Generate new maps in real-time from bottom detections.
► Beam stabilisation.
Beam stabilisation compensates for the movement of the vessel, providing accurate seafloor
profiles and fish school locations.
► Variable beam width.
Unique to the WMB-X230 the single beam view can not only be stabilised, but the beam width
can be varied from 5° to 40°.
► Triple beam view.
With variable width and angle, the port, centre, and starboard beams display together to help
build your understanding of the sea environment.
► Navionics chart overlay.
The charting displays can draw a vector Navionics hydrographic chart overlaid on the WASSP seafloor
data. The displayed chart features can be turned on or o as required. Maps are available from

Navionics to cover almost every part of the world.
► Bottom lock.
Bottom lock provides a traditional bottom lock mode where the changes in bottom depth are
ignored and the bottom is drawn flat. Fish and other echoes are shown relative to the flat bottom
image, enabling better discrimination between bottom fish and the seafloor.
► Computer based profile storage.
A computer-based system means the WMB-X230 can generate and store very detailed seafloor
profiles.
► Map resolution based on depth.
Your WASSP system dynamically changes the resolution of the stored maps to suit the depth of the
seafloor. Shallow seafloor data is stored at resolutions as high as 250mm to give the maximum detail
available, while deep seafloors have their resolution restricted to 4m to avoid saving spurious fine
detail.
► Database management.
The WASSP system uses one or more databases for storing and displaying WASSP data including the
depth, backscatter and water column information. Additional databases can be created at any time
and incoming data can be assigned to any database. Unnecessarily large databases can be downsized to save recording space.
► Digital signal processing (DSP).
Using DSP technology, the WMB-X230 can provide an indication of changes in seafloor hardness,
ideal for scalloping, crayfishing, and trawling where you want to understand and locate small
changes on the seafloor.
► 160 kHz operating frequency (WMB-3230).
Operating at a frequency of 160 kHz provides high seafloor definition at depths down to 200m.
► 80 kHz operating frequency (WMB-5230).
This frequency provides performance down to 500m with a slight reduction in the shallow water
< 60m performance.
► Depth and seafloor coverage.
Seafloor coverage is determined by the beamwidth in use: For a 90 degree beamwidth, the
seafloor coverage will be approximately twice the water depth. For example, 100m depth gives
200m seafloor coverage with 112 beams - every ping. For a 120 degree beamwidth, the seafloor
coverage is 3.4 x depth. For example 200m depth gives approximately 680m seafloor coverage.
► Unique power management system (14 power levels).
14 power levels provide optimal performance over a wide range of seafloor types and water
depths.
► More accurate seafloor - faster.
Profiles 90 times faster than conventional single beam echo sounders, leading to reduced costs
and improved accuracy.
► Future proof technology.
The computer based operating system and BTxR firmware are both upgradeable as new software
features are developed.

snapshot files.
2.10 Mapping Options
Used for interfacing seafloor and water column data to chart displays (see “4. Chart Display Modes” on page
18) and external viewers. This is useful for users who are recording to a database, but want to stop recording
temporarily, as the interfacing is an easy toggle ON / OFF. Both WASSP seafloor data and watercolumn targets
can be toggled.
These options only aect database recording for the Charting display, and will not stop raw data recording.
This button toggles seafloor detection recording for the Chart displays. When
enabled, the seafloor data as detected by the pinging transducer will be saved
to the current recording database.
When disabled, the charting display will not record the seafloor data detected
by the WASSP sonar.
See “6.9 Database Manager” on page 41 for more information on recording
databases.
This button toggles 3D fish marks recording for the Chart displays. When enabled,
3D fish mark information from the pinging transducer will be recorded for use on

Click this button to overlay the current Triple Beam configuration
onto the sonar display. The position (angle) and width of each beam
will be clearly visible. A RED mask for the port beam, grey mask for
the centre beam, and GREEN mask for the starboard beam.
Enable this to normalise the colours on the sonar display for
intensity based on power level, spreading and absorption loss.
Increasing the power will thus decrease the gain by a factor that
should mean the same fish echoes will be the same colour at any
power level.
This button opens the Fish Options window.

3.2 Single / Triple Beam Display
The Single / Triple Beam Display shows seafloor and water column information in a similar fashion
to the traditional fish-finder display. Signal returns are drawn vertically in slices, with new information
appearing on the right of the display, and old information dropping o the left side.
In Single Beam mode, only the middle beam is used to draw the information from the seafloor.
In Triple Beam mode, additional port and starboard beams are used to draw information from selectable
areas of the water column through configuration of the beam width and beam angle. See Figure 5.

Grid size selectable from 5 depth units to 100 depth units.
This adjusts the angle which the centres of the port and starboard
beams are set from the middle beam. Larger angles move
the beams further from the middle beam, and smaller angles
move the port and starboard beams closer to the middle beam.
The beam angle can be set to 5, 10, 15, 20, 30, or 40°.
This adjusts the width of the three individual beams used for the
Single / Triple Beam Display, and can be set to 5, 10, 15, 20, 30,
or 40° widths. Selecting a 10° beam width with a 20° triple beam
angle will therefore give a 50° swath for the Triple Beam view. See

Selecting this option enables the smoothing option for the Single
/ Triple Beam display.
Enable this to normalise the colours on the sonar display for
intensity based on power level, spreading and absorption loss.
Increasing the power will thus decrease the gain by a factor that
should mean fish echoes from the same fish will be the same
colour at any power level.
This is the method used by the program to constantly display the
seafloor during scanning operations regardless of the changes
in seafloor depth. This is indicated by the word (Tracking) being
tagged to the end of the words Manual Zoom in the Text Box
when the text box Status option is enabled.
Seafloor Tracking must be enabled in the Config sub-menu and the
Range Control dial set to automatic (GREEN). If Seafloor Tracking
is disabled in the config sub-menu, the word (Tracking) disappears
from the Text Box. If the Range Control setting is in manual mode
(YELLOW) and the seafloor then drops below the range setting, the
seafloor will stop being tracked (and lost from the screen).
This button enables the Triple Beam display. Triple Beam orientation
can be changed between Horizontal and Vertical in the System
Tab of the System Configuration Utility (see “7.1.4 System” on page
46).
This button opens the Fish Options window.
See “3.4 Fish Options” on page 16 for more details.
3.2.2 Display Oset (Shifting)
Zooming the Single / Triple Beam Display, by default, is centred toward the transducer location (0 m
depth), but the focus of the display can be changed by using a display oset.
With the Bottom Lock mode disabled, left-click on the Single / Triple Beam Display window and keep
holding down the left mouse button. By scrolling the mouse wheel, the zoom centre on the Single /
Triple Beam Display can be shifted from 0 metres depth (centred on the transducer), to deeper down
the water column.
Note: Right-click at a point on the Single /
Triple Beam display to send a mark to the
Charting display at the cursor location.
Advantages
à Shows past information.
à Width and colours of seafloor return can be used to help determine
bottom types.
à Adjustable beam width allows optimisation for full coverage or high
resolution to see small detail changes.
à Display redraws dynamically when range, gain, or zoom change.
Disadvantages
Ä Harder to relate the location of features seen to the vessel’s position.
Ä Does not show all information seen by the sonar view.

3.3 Sidescan Display
The sidescan display is another display type for viewing information generated from sonar data
received by the system. The display is drawn on the screen as a waterfall – the newest information
appears at the top of the screen, while the oldest falls o the bottom of the screen. This is similar to
the way the Single / Triple Beam Display operates, except that in their case, the new data appears on
the right and the old data disappears o the left of the display.
The left side of the Sidescan Display shows the signals received from the port side while the right
shows signals received from the starboard side. By default, the sidescan view starts at the centre of
the vessel and works its way out to port and starboard.
As the sidescan image moves further out along the seafloor, the picture shows features on the seafloor.
Objects such as rocks appear as bright white marks followed by a shadow. Harder ground gives strong
returns (lighter on the grey scale), while a patch of mud or kelp causes a dark patch/shadow to appear.
The primary advantage of the sidescan view over the other views is in locating and identifying objects
on the seafloor o to each side of the vessel. Some structures such as a shipwreck may appear like a
large fish school on the sonar view and thus not appear as an object on the other acoustic or chart
displays. Figure 7 shows how a wreck sitting on the seafloor can be distinguished as a clearly shaped
structure by using the Sidescan Display, allowing the user to interpret the sonar information from a
dierent viewpoint.
Due to the nature of the origin of the data, any signals of significant strength register as a faint mirror
on the opposite side of the display.

3.4 Fish Options
The Fish Options window contains preferences for watercolumn target detection. The user is able to
select any depth range and threshold for target detections, and view a detection histogram with an
adjustable 30 minute history. The settings contained in this window aect both the 2D and 3D fish
shown on the charting displays (NB: the 2D fish will ignore the history setting).
3.4.1 Fish Display Options
► Between Depths: The user can set a depth range for watercolumn
detections. The WASSP program will ignore detections outside of
this range.
► From Seafloor: If the user is only interested in near-bottom targets,
the From Seafloor option will only use detections that are located
a certain distance above the seafloor, ignoring the rest of the water
column. If Bottom Lock is enabled (see “Bottom Lock” on page
12), the Single / Triple Beam display will show a green line where
the detections start.
► From Range: If the user has set detections to “All Targets in Ping”
(see “System” on page 46), then the “From Seafloor” setting
becomes “From Range”. In this case, users are generally working in
deep water without a discernable seafloor. The detection range will
be from the last signal acquired up the water column. The depth of
the last signal will depend on the setting of the range dial.
3.4.2 Fish Threshold
Generally speaking, large fish return a stronger signal than small fish. The Fish Threshold control
dial allows you to tune the “Fish Detection” for your vessel. The control has a range of 1 to 30. It is
recommended that this threshold is set high enough that only the desired targets are ‘detected’. This
control also aects the fish shown on the charting displays as well as the Fish Histogram.
3.4.3 Fish Histogram
The histogram shows a gain-adjusted colour table to help reference the Fish Threshold to normalised
signals on the Sonar and Single / Triple Beam displays. The Fish Threshold setting is visible as a white
line on the colour table. By adjusting the Fish Threshold and referring to the histogram, you will find
an optimum level for your vessel’s installation.

WMB-X230 oers two modes for fish detection (Mode 1 and Mode 2). Both modes detect fish, but
vary slightly in their approach.
Seafloor discrimination settings will adjust how detections occur on outer beams. When discrimination
is set to none, the detection algorithm will try to detect targets as close to the seafloor as possible,
but may incorrectly identify part of the seafloor return as targets. When discrimination is set high, the
detection algorithm will try to ignore targets close to the seafloor in case they are part of the seafloor
return. Medium discrimination is a balance between the two.
