PREFACE
Note:
MAQ Sonar makes every effort to ensure the information contained within this document
is correct. However, our equipment is continuously updated, so we cannot assume
liability for errors, which may occur.
Warning:
MAQ Sonar disclaims any responsibility for damage or injury caused by improper
installation, use or maintenance of the equipment.
References:
This Technical Manual is intended as a reference only. The information contained in this
document is to be used in conjunction with the shipyards own vessel drawings,
documentation and engineers. Standards for installation are to be certified by the
installing shipyard, engineers and dealers. Further information about MAQ Sonar can be
found in the MAQ Sonar Operators Manual.
Manuals:
This manual must be kept aboard the vessel at all times. The information contained
herein is subject to change without notice.
Introduction:
The main purpose of this manual is to provide the information and basic drawings
required for installation of the MAQ Sonar system. In addition this manual contains
technical information which may be required in the future.
The MAQ Sonar electronics is capable of driving three different frequency transducers.
This is a generalized manual for all three types of transducers.
Responsibilities:
The installer is responsible for the equipment during the installation. The warranty is only
valid when the installation is made in accordance with this manual.
1) Approvals: Sea-Chest installations must be approved on a case-by-case basis with regard
to the vessel’s national registry and corresponding maritime authority. The ship owner
and shipyard performing the installation are responsible for obtaining installation
approval.
2) Power supply: For the Processor Units AC Power we recommend the use of an
Uninterruptible Power Supply (UPS). The UPS should have the ability to maintain power
for 10 minutes; This allows shut off of the equipment in the case of a AC power failure.
This also prevents shut off due to power surges/loses due to other vessel equipment.
Many Vessels are equipped with AC inverts. These must be Pure Sine Inverters with
sufficient power to support the system. Hoist DC power must be supplied from Vessel
Power sources. 22KHz will also require AC power for the Motor.
3) Dry Dock: Ensure proper clearance under Sea-Chest for sonar installation. Avoid placing
supporting blocks in the area of the Sea-Chest. In the Note section of this manual, log the
position of the Sea-Chest for future reference.
4) Wiring: All cables must be supported or protected along its entire length. Conduit or
cable trays should be used. Cables must be installed so as not to run in the areas of highpower supplies, antenna cables or other sources of interference.
5) Vibration: Vibration on any of the equipments must be monitored. Excessive vibration
will require dampeners to be installed. Improper installation on Transducer Guides can
result in Flow related vibration.
6) Temperature and Humidity: All equipment, unless otherwise specified, must be
protected from extremes in temperature and humidity.
7) Warranty: The warranty is only valid when the installation is made in accordance with this
manual. Note that the Warranty Registration Card must be returned by the vessel to MAQ
SONAR within 30 days of the installation to be validated (see the example below).

The MAQ Sonar system consists of the following components:
1) Computer interface unit (Processor) with Joystick unit. (An optional Keypad Control is
Available)
2) Hoist with Hoist Control unit (60 KHz and 90 KHz unit the same hoist system)
3) Transceiver Unit
4) Optional RDT Transmitter Unit (not Shown)
5) Transducer (90 KHz, 60 KHz or 22 KHz)
6) Monitor (not supplied by MAQ Sonar)

MAQ Sonar Sea-Chest Installation References
Approvals:
Sea-Chest installations must be approved on a case-by-case basis with regard to the vessel’s national
registry and corresponding maritime authority. The ship owner and shipyard performing the installation
are responsible for obtaining installation approval.
Dry Dock:
Ensure proper clearance under Sea-Chest for Sonar installation. Avoid placing supporting blocks in the
area of the Sea-Chest. Ensure you record the position of the Sea-Chest for future reference. Sonar have
been installed in existing Sea-Chest without placing the vessel in Dry Dock but this is at the discretion of
the vessel owners and Dealers.
Sea-Chest:
MAQ Sonar is one of the simplest and fastest Omni Sonar to install. This Sonar was designed to fit on
vessels with existing Sea-Chests and can be installed in as little as one day.
The Sea-Chest is probably the most important consideration when installing Sonar. For best performance
the transducer must extend properly out of the Sea-Chest in order that the active face is fully exposed
(Short Stroke). When it is extended farther below the keel it will not be exposed to air bubbles which
may be driven under the vessel which will reduce Sonar performance (Long Stroke). Many vessels do not
have an issue with air bubbles from the Bow of the vessel and short stroke installations are more than
adequate.
The recommended location for the Sea-Chest is 1/3 of the vessel length from the Bow and as close to the
keel as possible. For assistance Please contact the Factory tech@maqsonar.com .
There are several other
considerations for locating a SeaChest. When the vessel is already
equipped with Sonar these Sonar
may extend in front of or next to
the MAQ. If the equipment is in the
line of sight of the MAQ they will
create a shadow or block the
detection of the Sonar in this
direction.
Although MAQ Sonar will fit in any 8” (90KHz and 60KHz) or 18” (22KHz) Sea-Chest, Sea-Chest extensions
may have to be added to accommodate the MAQ. It is critical that the I.D. of a Sea-Chest extension
matches the original Sea-Chest I.D. and that the extension is aligned properly with the original SeaChest.
Before proceeding with the installation, please reference the attached Installation drawings and

diagrams. These drawing show typical lengths and dimensions for short stroke and standard stroke hoist
installations of the 90KHz, 60KHz and 22KHz Sonar.
Before installing the Sea-Chest or Sonar it is IMPORTANT to measure the angle of a vessel during
typical search and catch situations as well as pitch and Roll measurements. Sea-Chests, that were
angled as much as 10° off the typical vessel angles during standard Sonar operation have been
observed in the past. This will make operation of OMNI Sonar very difficult and also reduces
performance greatly.
These issues should all be considered on installations in new or existing Sea-Chests.
Sea Chest and Hoist Size Listings
CONSULT FACTORY FOR MINIMUM SEA CHEST LENGTHS AS SHORT SEA CHEST MAY CAUSE EXCESSIVE
VIBRATION. CONSULT FACTORY WITH SEA CHEST DIMENSIONS FOR APPROVAL
INSTALLATION OF 22 KHz TRANSDUCERS IN 16” SEA CHESTS IS NOT RECOMMENDED. PLEASE CONSULT
FACTORY WITH SEA CHEST DIMENSIONS FOR APPROVAL
Grounding and Zinc Anodes:
MAQ Sonar’s Transducer Pipe, Transceiver and Processor Units must be
electrically connected to the ships main ground.
Zinc Anodes must be installed on Transducer pipes and inspected and
replaced yearly.
