Navigator: Diver Held Sonar Imaging and Navigation System

A one man Navigation and Sonar Reconnaissance unit.

The Navigator is a second generation Sonar Imaging and Navigation System, designed by Shark Marine primarily for MCM and SAR use.

The Navigator is in use by many of the worlds Navies, and has become a trusted piece of their standard kit and reshaped many of their SOPs.  The modularity of the system and numerous advanced sensors available allow the Navigator be to become a force multiplier, enabling smaller groups to cover more ground in less time.

Many Police forces and Fire Departments are also using the Navigator in homeland security / search and recovery roles as well as scientific organizations, and commercial dive companies. 

The Navigator is the most modular system of its kind, enabling it to be quickly configured for any application.  The modularity of the system also means that it will never become obsolete, as technology advances in certain areas these components can be replaced, rather then needing to replace the entire system.  Shark Marine’s DiveLog software controls all operations of the navigator and its accessories, operators need only learn one software to master all their equipment.

Surface GPS

Option - Surface GPSThe Surface GPS can be used when the Navigator is functioning on the surface.  It also works well as a rapidly deployed system where it would provide the initial position fix for the DNS.

Floating GPS

Option - Floating GPSThe Floating GPS provides positioning in shallow waters.  This system can also be periodically deployed to the surface to remove any time accumulated error when using the DNS for long range covert operations.

Pole GPS

The Navigator Pole GPS was designed for use with the Rapid Beach Profiling system, or other applications where the operator will be swimming on the surface.

Doppler Navigation System (DNS)

Option - Doppler Navigation SystemThe Doppler Navigation System tracks the divers movement over the sea floor.  As a result it does not require a satellite fix or base stations once its initial position has been set.  The DNS is an ideal set up for covert rapid deployments (when paired with the surface GPS) or to fill in any gaps caused by acoustic shadows when using the LBL system.

Long Base Line (LBL) Positioning System

Option - LBLShark Marines LBL system provides high precision underwater navigation without the need for a floating GPS  or tethers to the surface.  This system can use 2 or 3 base stations which can be rapidly deployed from any small craft or by a diver.  The LBL is the system of choice for any long duration underwater searches.

Motion Reference Unit

The Extended MRU option provides the Navigator or Dive Tablet with a more accurate compass and full 360 degree pitch and roll orientation data. Highly recommended for use on the Navigator with forward-looking sonars and the Doppler Navigation System for more accurate positioning.

Forward Looking Sonars


P-450 Series – Long Range:

The P-450 series forward-looking sonar is the best solution to detect, monitor, and track objects and/or targets at distances up to 300 meters (984′). The P450 is available with a 45°, 90°, or 130° field of view.

Frequency: 450 kHz
Range Max: 300 m (904′)

P-900 Series – Mid Range:

The P900 series forward-looking sonar is the ideal sonar for underwater detection and identification operations up to 100 meters (328′). The P900 series is also available with a 45°, 90°, or 130° field of view.

Frequency: 900 kHz
Range Max: 100 m (328′)

 P-900-2250 Mid – Short Range:

The P900-2250 forward-looking sonar combines a medium range 900-45 navigation and inspection sonar with the identification capabilities of a higher frequency 2.25 MHz sonar head.

Frequency: Selectable 900 kHz 2.2MHz
Range Max: 100 m(328′) 900kHz 12 m (39′) 2.25MHz

Sound Metrics Aris:

The Sound Metrics Aris sonar is a dual frequency unit that provides extremely high resolution imagery at short range, well suited for detailed inspections and target identification.

Frequency: Selectable 1800kHz, 3000kHz
Range Max: 15 m (50′) 1800kHz and 5 m (16′) 3000kHz

Tritech Gemini:

At 750kHz the tritech Gemini is well suited for medium to long range searches (150 m (492′)).  The wide even image of the Gemini allows this sonar to make very clean mosaicks.  Its small size also make it a perfect fit for Shark Marine’s Navigator DT2 system.

Frequency: 750 kHz
Range Max: 150 m (492′)


PRO-MAG - Magnetometer

Option - PRO-MAGThe PRO-MAG is a high sensitivity Overhauser Magnetometer that can be equipped on the Navigator to locate objects with ferrous content. 

725K Metal Detector

725The Ebinger 725K is a field proven, valuable tool for underwater ordnance detection. When integrated with the NAVIGATOR its abilities are further enhanced with the addition of a visual data display and the navigational features of the system.

Radiation Detector

Oprion - Nav-RadThe Shark Marine radiation detector is a plug and play unit designed to detect gamma radiation underwater. 

Bathymetric Sonars

Option - Altimeter SonarSonar Altimeter:

The Sonar Altimeter measures the distance to the seafloor.  The Sonar Altimeter can also be used to gather bathymetric / beach profile data.

Option - Multi-Beam ProfilerMulti-Beam Profiler:

The Multi-Beam Profiler can be used to gather bathymetric data.  The Multi-Beam covers a much larger swath then the Sonar Altimeter.

Option - Transom Mounted Altimeter SonarTransom Mounted Altimeter Sonar:

The Transom Mounted Altimeter Sonar is used for the Rapid Beach Profiling System (RBPS). It was designed to quickly mount to vessels of opportunity for collecting bathymetric and beach profile data.


Starfish Side Scan Sonar

Starfish 452FThe small size of the Starfish Side Scan Sonar makes it a good match with the Navigator.  Powered and controlled by the Navigator the Starfish can be towed by any vessel of opportunity or by the MAKO Diver Delivery System.

Underwater Head-Mounted Display (UHMD)

Option - UHMDDesigned for use in zero visibility situations, or for operations where a low light signature is required, the Underwater Head Mounted Display (UHMD) brings the NAVIGATORS display right to the divers mask.  The UHMD is available as a monocular or binocular version.  Mounts are also available for different masks or helmets.


Option - NavCamThe NavNam is a plug-and-play digital camera that mounts onto the Navigator. It can capture still images up to 1920 x 1080 and video up to 1280 x 720, which are geo-referenced (if a position is available), and digitally stored in the DiveLog project.

Sub-NET Communications System

Option - Sub-NETSub-NET is an underwater communication system that allows multiple Navigators to communicate with one another or to surface vessels or other assets.  Sub-NET also allows connected Navigators / other assets, to share their locations with one another, as well as send target information and waypoints.

MAKO Diver Delivery System

P1040590The MAKO DDS marks a new evolution in diver transportation by combining a propulsion device with the Shark Marine Navigator. The combination provides a system that is capable of automated flight paths, from a simple “Goto Target” to complex survey routes, while providing the diver with full navigation and forward looking sonar imagery to locate and view targets up to 300 meters (904′) away.
