Introduction
General Overview
The DMD system has been designed to provide divers with the ability to navigate and carry out
inspections in zero visibility conditions.
Utilising the Gemini range of Multibeam imaging sonars allows the user to select the most suitable
sonar for the type of operation required. Employing a high degree of resolution and field of view the
diver can opt for either the Gemini 720ik or Gemini 1200ik Multibeam imaging sonars, both provide
excellent range, resolution and field of view. These high specification Multibeam imaging sonars
provide a diver with a high degree of confidence while working in zero visibility conditions and allow
searches to be undertaken farmore efficiently thanusing conventional search patterntechniques. The
DMD systems have been designed to be used with the Inodive accessory rail system, allowing for the
DMD system to be used with an extensive range of dive masks and helmets. All of the Gemini sonars,
when supplied with a DMD system, are built-up with an Inodive interface to allow for seamless
installation onto the dive mask/helmet.
Power and control of the DMD system can either be through a tethered connection to the surface,
where the topside operator controls what the diver sees, or the diver can work autonomously with no
need for a surface connection by utilising a diver battery pack and DMD hand controller.
The tethered system (DMD-T) is intended primarily for surface air dive systems where the supplied
tether connects the diver to the surface and control of the sonar is undertaken by the support team.
The same DMD-T system can be used by scuba divers, where it’s acceptable to be attached to the
surface by the tether.
The untethered system (DMD-U) allows the diver to operate totally independent of a surface
connection, with the diver himself taking control of the sonar operation. This is of particular benefit
where a diver wishes to operate in a covert fashion or where there may be hazards that the tether
could get snagged on.
By using the DMD system, a diver has the ability to view the sonar image on the diver mounted
monocle, allowing the diver to quickly and efficiently locate targets of interest. The DMD-U system
allows the diver to adjust settings using a custom hand controller and record data of interest on the
subsea computer, while the DMD-T system allows the support diver on the surface to make any
necessary adjustments to the sonar settings and highlight any targets of interest for the diver to
investigate.
The Inodive rail system simplifies the fitting and removal of the DMD system. This allows the sonar to
be removed from the mask/helmet and attached to a Gemini sonar pistol grip where this may at times
offer some advantage, such as difficult to reach areas or where a different sonar viewing angle may
be beneficial.
The innovativeMonocle design allows for it to beaccuratelypositioned onthe divers helmet/mask and
yet it can also easily be lifted out of the divers view and later replaced back into the same position by
the diver when it’s required.

Hardware Installation & Configuration
The full DMD system is contained within 4 separate rugged deployment transit cases
These are
•DMD SCU
•DMD Instrument Deployment Case
•DMD Diver to Surface –Deployment Case
•DMD Sonar Deployment Case
DMD Surface Control Unit (SCU)
The DMD SCU case is a self-contained rugged transit case featuring integrated connection points on
its rear which provide all the surface connections required which power run and deploy the system
onto a diver. Securely mounted within the DMD SCU are x2 Li-ion battery packs linked into an
intelligent charging circuit.
To comply with IATA shipping regulations the Toughbook laptop should not be
retained within the DMD SCU when the unit is presented for international air
transportation. The ‘Air Transportation Fuses’ at F1 & F2 on the rear of the SCU
should be removed and stored separately (this will isolate the Li-Ion batteries). The
Toughbook should be shipped separately within a purpose defined space contained
within the DMD Instrument Deployment case
