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 far
more efficiently than using conventional search pattern techniques. 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 innovative Monocle design allows for it to be accurately positioned on the 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 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
