The Tritech Typhoon colour underwater video camera has a 22:1 auto focus zoom lens within a 3000m housing. Manual Focus and Zoom may be controlled using conventional Analogue signals or via the integrated RS232 Interface.

The ¼ Type CCD Sensor provides a high-resolution 470 Horizontal TV Line colour picture. When operating under low light conditions the shutter speed reduces to provide a light sensitivity of 0.1 lux.

Commonly overlooked in underwater cameras is the importance of a high quality view port. The Acrylic view port used on Tritech cameras has similar refractive properties to that of water providing a sound basis for the use of a plano-concave view port, which is the preferred lens type for deep water rated lens.

This plano-concave view port reduces the effects of refraction and also removes the effect of chromatic aberration. This results in a camera that provides a crisp picture during close proximity viewing in murky water.

Supplied with a switchable long line amplifier the Typhoon underwater video camera is suitable for use with short, medium and long umbilicals.

• High resolution 470 horizontal TV lines

The technology behind the CAT II:
CAT II is in the category where two GPS receivers and two antennas are combined to be able to measure heading. The technology is single frequency (L1), GPS, phase measurements and RTK (Real-Time Kinematic). Apart from the heading added this principle offers better position stability and better speed accuracy compared to CAT I. A built-in rate sensor makes the system robust in its overall performance. Differential corrections from EGNOS, WAAS and MSAS are standard and corrections from shore beacons are a feature that can be added.

• General navigation
• Accurate channel navigation (positioning)
• Precise heading and ROT information
• Precise speed information
• Berthing tool (if a speed error of up to +/-2 cm/seconds can be tolerated)
• Transponder functions via UHF, GPRS or UMTS
• Reception of weather data, VTS targets and radar overlay
• PPU, TDMA transponder functionality (Transmission of
own position).

The technology behind the CAT III:
CAT III is the highest level in satellite positioning. Similar to CAT II it operates with two receivers to provide heading. CAT III is a dual frequency (L1 + L2) receiver, phase measurements and RTK. Accuracy is position jumps to centimetre and heading accuracy to 0.02 of a degree. These extreme accuracies allow us to make reliable prediction calculations. The E-Sea Fix CAT III also has motion sensors integrated that compensates for Heave, Pitch / or Roll and keep track of ROT (Rate Of Turn). These parameters are also essential for the prediction of accuracy end-result. The CAT III satellite receiver gets signal from not only GPS but also GLONASS and in future also GALLIEO. With this increase of available satellites the E-Sea Fix CAT III can operate under the most critical situations such as obstructions from cranes, bridges and ships own masts, antenna etc. ‘

• Extremely precise position accuracy under all conditions
• Ultra precise heading and ROT at any time
• Precise speed information at any time
• Berthing tool (2 to 4 times more accurate than CAT II) accuracy equal to laser system
• Reception of VTS targets and radar overlay
• PPU, TDMA transponder functionality (Transmission of own position).

It’s reliable signaling technology that has saved more than 26,800 lives since 1982.

• Full functional self-test including battery voltage and internal circuitry
• Bright LED strobe conserves battery power without sacrificing intensity
• Single, three-position switch for easy test and operation
• Lanyard coiled on recessed spool for nontangling deployment
• Non-Hazmat Battery

Performance Tether - 8mm diameter (standard length: 40m)

The performance tether is a thin and flexible, neutrally bouyant tether - ideal for shallow water work. When using long tether configurations we would normally start with a length of 40m performance tether at the ROV end because of the excellent flexibility and low drag characteristics. This tether has higher power losses than the other types of tether, so is normally supplied in short lengths.

Neutral Tether - 10mm diameter (standard length: 76m)

Flexible, neutrally buoyant tether. This is the standard tether on many VideoRay systems. The thicker diameter wires mean there is less power drop than the performance tether so it is suitable for use in longer tether configurations. The neutral buoyancy and good flexibility ensures that it does not compromise ROV manouverability.

Negative Tether - 8mm diameter (standard lengths: 76m, 152m, 228m, 305m)

The negative tether is negatively buoyant, making it ideal for operating in deep water environments, or areas with snagging hazards near the surface of the water. It also has the best power performance of the 3 tether types making it ideal for use in long tether configurations.

Utilising a wide transducer aperture, the SeaKing Hammerhead has a very fine mechanical step size and proven DST technology, for outstanding image quality. The operational range of the SeaKing Hammerhead is increased with two frequencies; a high chirped 935 kHz frequency to enable high resolution imagery and a second chirped frequency, 675 kHz to allow for long range capability. The wide transducer design allows for a very narrow horizontal beam to be created on both frequencies, to increase image resolution.

In addition, the SeaKing Hammerhead has a built in attitude sensor, which makes the unit ideal for tripod deployment, giving the user a clear indication as to the position of the unit relative to the seabed. The unit also has an integrated three axis compass, to allow the sonar image bearing to be continually displayed and updated. The SeaKing Hammerhead can be easily networked with all products from the SeaKing family.

A thin “membrane” panel is included with the HAWK BOARD. It can be mounted and sealed to a flat surface with an adhesive. If the application requires a water tight seal LYYN recommends some extra mechanical mounting. The panel is connected to the HAWK BOARD with a flat cable (included). User controls: On/Off, LYYNification level in 9 steps, Selection Window On/Off.

• PAL or NTSC video, auto sensing, micro connectors on the board
• S-Video (separate luminance and chrominance)
• Direct Analog Bypass when unit is powerless
• Two control ports, one for control panel (a standard panel included) and one for software control through a RS interface.
• Nominal input voltage: 12 Vdc, 0.1 A.

Each video frame is optimized for contrast and color spectrum to make it as “natural” as possible to the human eye. Even the smallest fragments of color and object shape can be extracted from the camera sensor. And all this is done in real-time.

The result is an image that constantly self-adjusts to the environment.

PRESENTATION OF INFORMATION

The data is available from the office PC, which will be running the MARIMATECH Dockmaster Windows software.
There are a number of different ways to present the information to the operators outside. The most common way is to use the large displays typically mounted on the jetty, which can be seen up to a range of 300 metres. Another option is to use hand held pagers or PDA’s.

SYSTEM DESIGN

The devices in the MARIMATECH systems are linked by using LMS4 Ethernet building blocks.
The LMS4 is a unique designed microcomputer with a built-in LAN switch, memory and enough processing power to preprocess the raw data from sensors such as lasers etc.
The benefit of the LMS4 design is that the PC is no longer the central computer but just a monitor.

SYSTEM INTEGRATION

MARIMATECH is a specialist in system integration. Not only do we integrate our own systems but also other relevant systems on a marine jetty complex. In most cases the central control cabinet is designed for the individual system according to the client’s standards. This covers, support relevant to UPS, cable data networks, fibre optical networks as well as wireless networks of various technologies. Back-up systems on different levels are our specialty as well as LAN/Ethernet solutions.

An all-in-one 19” display with integrated PC, the system is compact and easily installed on a short pedestal on the chart table, long pedestal or console-mounted.  We also offer larger screen options including 20.1”, 23.1” and a new ‘widescreen’ 27”, which are supplied as a separate screen and rack-mounted PC.

Fully integrated with the UK Hydrographic Office "e-Navigator" planning and chart update service.

All systems are delivered with computer based training (user training courses are also available on request)

Designed to be complementry to the Micron DST sonar, it can also act as a stand-alone altimeter, providing accurate height off the seabed and other subsea distance measurements.

The Micron Echo Sounder DST is a robust professional offshore or freshwater altimeter, built to the highest quality standards. It is optimised for operation on small vehicles, as it is both compact and very lightweight in water.

It is an ideal OEM product, being able to accomodate a wide range of voltage inputs. Other options such as increased depth rating are available upon request.

The Micron Nav system is an innovative USBL positioning system designed for small ROV / AUV. It has been primarily designed to be used in conjunction with the Tritech Micron / SeaSprite sonar and other Tritech Micro products. This concept will also be adapted and integrated into the Tritech SeaKing range of products in the future.

The system comprises of a subsea Micron Nav unit, a surface USBL transducer unit with integral Magnetic Compass and Pitch / Roll sensors, a surface Micron Nav 100 interface module and operating software under control of the customer host PC / Laptop.

Micron Nav uses the very latest in Spread Spectrum acoustic technology. This provides a robust method for communications between the dunking transducers and the vehicle responder / transponder.

It can be used as a stand-alone system, powered by and communicating with the Micron Nav through a spare RS232 port on the ROV (at 9600 baud) or RS485 through a spare screened twisted pair in the umbilical. Alternatively it can be integrated with the Tritech Micron / SeaSprite sonar communicating via the sonar RS232 aux port.

The USBL transducer is designed to provide 180 degree hemispherical coverage below the transducer, allowing vehicle tracking in very shallow water. The design of the ROV Micron Nav transducer provides omni-directional coverage.

Quick and easy to mobilise.

Integrated motion sensor in dunking transducer.

Seamless integration into Tritech Seanet Pro software control system.

Can connect via the 'aux port' of Tritech sonar systems - no need for extra umbilical communication channels.

If the new generation of very small and low cost ROV are to develop their full potential it is essential they are equipped with the vital tools and sensors expected on larger ROV. Along with the camera, the most important sensor for any ROV is its obstacle avoidance sonar.

The Tritech Micron DST (Digital Sonar Technology) Sonar sets new standards in compact sonar technology. It is the smallest digital CHIRP sonar in the world. CHIRP technology dramatically improves the range resolution compared with conventional sonars - it is a feature normally associated with much larger, more expensive systems.

Based on experience gained from Tritech's world class range of industry standard SeaKing and SeaPrince sonars, the Micron DST Sonar incorporates the most advanced acoustic features and software available today.

The Micron DST Sonar can be controlled by a customer supplied PC or laptop and it can be configured for either RS232 or RS485 protocols. The sonar has a standard auxiliary port to allow it to interface with other Tritech sensors.

The Micron DST Sonar incorporates the very latest surface mounted digital electronics and many software features normally found only on full sized commercial sonar systems. Tritech believe that although the Micron DST Sonar is small in both size and cost it should offer the full range of functionality expected from a professional sonar product.

Unlike receive only AIS devices which do not transmit vessel information to surrounding traffic, the Nauticast-B system allows you to virtually participate in neighboring vessels maneuvering activities for collision avoidance. Announce your identity, position, speed and course over ground to oncoming traffic allows for increased security that you will be seen in low visibility conditions.

Avoid not being seen because of extreme weather conditions or busy vessel traffic environments. Generate a safety distre ss message to surrounding AIS equipment, including vessels, base-stations, and possibly SAR teams. All in all, it is a horizon expanding experience; especially in combination with an electronic chart system.

The hard case can withstand the rigors of the marine environment as well as multiple deployments. Corrosion resistant IP65 rated connectors enhance the system reliability and connectivity. This unit is capable of being set up and running within minutes. Once the transponder is powered up and programmed with ship’s static data easy to install VHF and WiFi antennas complete the installation.

With a fully charged internal battery, the portable system can operate for 3 hours or indefinitely when connected to ship’s power. Interfacing with the ship’s sensors and ECDIS displays is made easy with the external case mounted ports and optional cables. Built in WiFi allows for communication with PC ECS software.

This transponder is compliant for Inland and SOLAS applications. 

Our state of the art receiver uses highly sophisticated AIS software which allows for its small size and low cost.

The marine grade, water resistant housing mounts discretely below deck or in an electronic box.

AIS increases navigational safety by receiving vessel identification, position, course and speed of other AIS equipped vessels and base stations. This helps reduce the difficulty of identifying ships when not in sight and understanding their navigational intentions.

Built-in multiplexer for additional NMEA0183 devices

Dual Channel receiver ensures that all AIS messages are received, both Class A and Class B messages simultaneously

Exceptional receiver sensitivity ensures maximum range in the field

Full power ROV systems in extremely small and light packages, the Reservoir ROV (RESROV) and Hot Water ROV (HOTROV) are designed specifically for safe and painless inspections of drinking water reservoir tanks, and hot water systems, respectively.

The V4 can be delivered in a special configuration based on heat-resistant components, dubbed HOTROV. As a world first, this allows the V4 to be used for inspections inside active hot water accumulator tanks. HOTROV will tolerate 65°C continuously, and 75°C momentarily.

The V4 can also be delivered in a certified drinking water safe configuration for use in any type of water reservoir. Both versions may also be equipped with metal thickness gauges, high-pressure cleaning heads, suction heads and sensors for water quality measurement.

ROVPack

The small size and weight of the V4 in combination with the carrying concept ROVPack makes it easy and safe to access tight and hard-to-reach areas

Such areas, for example water towers and reservoirs have previously been restricted to micro-ROVs. With these innovations it is now possible to use a full-power vehicle, equipped with the entire range of sensors, cleaning equipment and tools available for the standard V8 Sii.

A full system can easily be transported and operated by two people.

The Tritech SeaKing Towfish Side Scan Sonar System is an extremely compact and low cost high definition side scan sonar system. The Towfish side scan sonar is designed for a wide range of seabed survey and inspection duties.

The SeaKing Towfish Sonar is available with two operating frequencies. The high frequency 675kHz side scan sonar has the greatest resolution and a useful range out to 75 metres on either side of the survey tow track. The mid frequency 325kHz side scan sonar has a useful range in excess of 200 metres either side.

The towfish sonar is designed to tow cleanly and with excellent stability under all towing conditions. The towfish body is fitted with durable Polycarbonate stabiliser fins. In the event of ground contact, the fins will break away from the sonar body and are retained for recovery by a shock cord line.

The towfish side scan sonar has a weak link and safety recovery line. If the towfish hits an obstruction the weak link will part but the sonar will not be lost. The towfish side scan sonar is small and light and may be manually deployed and operated by a single person from very small boats thus making it ideal for inshore and coastal applications.

In common with all Tritech sonar systems, the SeaKing Towfish Side Scan Sonar may be connected to a Seanet SCU surface control and display unit or most standard laptops and PC's. In addition to the display of side scan sonar data, the system will take position input from DGPS. This information is recorded with the side scan sonar data to allow a 'fix' of a target.

All data produced by the towfish side scan sonar system is processed within the towfish and transmitted to the surface in digital format. All data from the sonar may be stored on the built-in zip drive, in the Seanet SCU.

Building on the success of our advanced side scan sonar systems Tritech announces the next generation model, the SeaKing Towfish SK150 DST. Specifically designed to fly at depths of up to 120 meters, the SK150 side scan can be used for high resolution surveys at depths other lighter systems can't reach.

The SK150 combines the very latest Tritech DST (Digital Sonar Technology) electronics with industry leading transducer design and digital CHIRP signal processing techniques to dramatically improve range resolution and generate sonar images of unprecedented clarity.

The advanced 150kHz composite transducer assembly provides superior image quality and long range.

The SK150's simple, modular design provides increased reliability and facilitates quick in-field repairs should any damage occur during operation. All electronics are located in a single subsea pressure housing isolated from the rest of the towfish. The stabilising fins can be cheaply and easily replaced and a simple sheer and recovery mechanism is provided in the event of the SK150 side scan becoming snagged.

As part of the Tritech SeaKing suite of survey sensors, it is possible to run the SK150 with other SeaKing sensors over one communication link. The SeaKing Towfish SK150 DST may be connected to a Seanet SCU surface control or most standard laptops and PC's with Tritech Seanet Pro software installed. In addition to the display of side scan sonar data, the system will take position input from GPS. This information is recorded along with the sonar data to allow a 'fix' of a target.

The SK150 Towfish side scan sonar is fully compatible with all Kiltec and Easyreeling electric winches.

• Wide range up to 300m
• Extremely cost effective side scan sonar
• Easy to deploy and recover
• Low power and data rates
• Compatible with Tritech SeaKing product family

Its low power consumption and proven network reliability make it a cost-effective, low-maintenance, end-to-end solution for today's ship security requirements.

Ocean Alert software upgrade ensures full LRIT compliance

Existing Ocean Alert satellite terminals can also with a simple software upgrade fulfil Long Range Identification and Tracking (LRIT) compliance in line with the International Maritime Organisations (IMO), SOLAS V19-1 regulations.

The Ocean Alert solution was futureproof designed ensuring a single piece of equipment would fulfil the requirements of both LRIT and SSAS regulations. Avoiding the need for vessel operators to source new hardware and ensures compliance at a low cost.

The equipment will automatically identify the type of message to be sent, either LRIT or SSAS, and automatically mark if for the correct destination, thus ensuring that it is successfully delivered to either the Flag State for LRIT or the vessel operator for SSAS.

Comprehensive Tracking and Security Monitoring

Ocean Alert combines location tracking with security monitoring. The system will automatically transmit a ship's precise location to the fleet operating company at customer-defined intervals - typically every 6 hours - via Satamatics' worldwide telematics network, while also monitoring the multiple security-alert activation buttons that can be deployed around a vessel. In an emergency situation, triggering any of the covert activation points will immediately transmit automatic SMS text and email alert messages, to the fleet operator's chosen points of contact and to the flag state appointed authority. Once triggered, Ocean Alert will automatically increase the position reporting frequency to every 30 minutes until the emer gency has been resolved - this allows a ship's precise location to be tracked, identifying which alert activation point has been triggered, and reporting any tampering with the external power supply.

Satamatics' user-friendly web interface also allows fleet managers to nominate contact names, mobile phone numbers and email addresses to receive the automatic alert notifications. These can include emergency-alert activations and power supply interruptions, as well as exception reports - for example, when a vessels moves outside a pre-determined zone, reaches a particular destination or a hatch is opened without authorisation.

As part of Satamatics service, all Ocean Alert systems send an "over-the-air" test message once a day, informing chosen individuals that the system is working correctly. This gives users confidence in our solutions as they know their Ocean Alert is in working order.

Additionally, users can add to their solution web-based mapping. This gives users the option of viewing their entire fleet of ships on a world map or alternatively zoom into an individual vessel's precise location.

Advanced Terminal Technology

Sealed and certified to IP66 for operation above decks in heavy seas, Ocean Alert’s compact and concealable omni-directional antenna has a "look angle" of elevation less than five degrees above the horizon, ensuring unrivalled levels of operation.

To ensure there is no interruption to service all Ocean Alert solutions have an integrated back-up battery that will automatically switch into action if there is an interruption in power supply, malicious or accidental. The terminal will immediately broadcast a message stating there is a problem and will switch into "power-saving" mode, while continuing to monitor the covert activation points for further tampering.

The original StarFish 450F sonar offers a powerful, yet affordable, entry level side scan sonar system for shallow water survey work. Since its launch, the StarFish 450F has gained worldwide recognition as the most portable, affordable, towed side scan sonar on the market. Powered by a 450kHz CHIRP transmission, the 450F provides wide range sonar coverage up to 100m/ 300ft per channel (200m/ 600ft total swathe) with good, clear image definition.

Simple Operation

StarFish systems have been designed to be ‘plug & play’, connecting to your PC/laptop via a top‐box with USB connection. The topbox allows the sonar to be powered from both AC (i.e. mains supply) or DC (i.e. battery, generator) sources and multiple adaptor cables are supplied with every system, making it straightforward to power the StarFish system from your existing power source. Our intuitive StarFish Scanline software, designed for Windows operating systems, has an easy‐to‐use interface. With helpful ‘Wizards’ to get you started, you’ll be up and running in no time. For more experienced operators, enabling advanced features within the software is extremely simple to implement through the clever use of interactive displays, tabbed menus and ‘Widgets’.

CHIRP

Utilising the latest in advanced CHIRP (Compressed High Intensity Radar Pulse) acoustic technology and digital‐signal‐processing (DSP) techniques at the core of its imaging capabilities, StarFish sonar systems have the ability to detect small closely spaced targets at far greater distances than conventional single frequency, monotonic systems. By sweeping the acoustic transmission from one frequency to another, the bandwidth of this ‘chirped’ signal allows closely spaced targets to be imaged individually instead of typically becoming merged into one larger target. CHIRP techniques also help to remove random or out‐of‐band noise, therefore reducing the risk of acoustic interference.

All starfish systems have been specifically designed for shallow water survey in depths up to 30m/ 100ft. This makes them ideal for port & harbour survey and security operations, inland water survey of rivers/ canals/ lakes, wreck location and Search and Recovery (SAR) missions. StarFish towed systems are extremely portable, with each sonar less than 15” long.

The Tritech Super SeaPrince DST (Digital Sonar Technology) is an all-new sonar incorporating everything that we have learnt from previous generations of SeaPrince Sonars and the industry standard SeaKing and Micron DST sonars.

The Super SeaPrince DST Sonar is designed specifically for survey, observation and light work class ROV. The sonar is a single transducer, full digital CHIRP system, complementing the larger dual transducer Super SeaKing DST Sonar.

This core product sets new standards in sonar technology; its advanced composite transducer and CHIRP signal processing generate images of unprecedented clarity and resolution.

The Super SeaPrince DST is available in two configurations with either single or dual port pressure housings. This enables the sonar to function within the ArcNet network and interface with Tritech and third party products.

The standard depth rating of a Super SeaPrince DST Sonar is 4000 metres. It has all the functionality expected of a Tritech professional offshore sonar. Amongst its advanced capabilities are instant scan reversal, sector scan, image measurement, inverted head operation and true acoustic zoom.

Super SeaPrince DST CHIRP's around its optimised frequency of 675kHz. The sonar is extremely rugged, built to the highest quality standards and with a hard boot to protect the transducer.

The Super SeaPrince DST Sonar may be operated by the Tritech Surface Control Unit (SCU) or a customer supplied PC or laptop. As part of the SeaKing family, the sonar can be run simultaneously with other SeaKing products on a single ArcNet communications link, using the same processor and display. The sonar can also be configured for either RS232 or RS485 protocols.

Built to survive in the harsh underwater inspection environment, Tritech Super SeaSpy video cameras have been designed to be compact and rugged while at the same time provide a high quality colour picture.

The Super SeaSpy camera has integrated white ring LED's providing uniform illumination across the viewing area. A feedback loop automatically adjusts the lighting level so that optimum picture quality is achieved, regardless of the reflectivity of work surfaces. This integral lighting provides an underwater camera that is well suited for close proximity inspection work where little or no lighting is available.

The light can also be adjusted manually, thanks to a single wire control, compatible with several standards. In a warm environment, the LEDs are protected by a temperature sensor.

The Super SeaSpy has an internal focus adjustment that allows the focal range to be set between 50mm and infinity. The camera power supply provides excellent protection for the efficient operation of the camera module. Fitted with an integral video line driver the Super SeaSpy compensates attenuation of the video signal when used over various umbilical lengths. This line driver is adjustable and is protected against overvoltage.

As with all of the Tritech underwater video cameras the Super SeaSpy camera is fitted with a high quality water corrected viewport to optimise the picture quality. This water corrected viewport results in a video camera that provides a crisp picture during close proximity viewing in murky water.

A depth rating of 300 meters is standard, and improvements in the electronics allow for greater total tether length (up to 500 meters) and much better power transmission over long tethers.  New sensors, including a 3D compass and MEMS gyro improve navigational capabilities.  A high quality video camera & high intensity LED lighting allow for very clear video and stills to be recorded, particularly in difficult lighting conditions. 

The intuitive "VideoRay Cockpit" control software allows more functionalilty and diagnostics than were ever possible with earlier ROV systems. VideoRay's commitment to making software updates available free of charge, ensures that existing customers will always have access to the latest features.

The Pro 4 is sold in a variety of configurations designed to suit common ROV applications. Configurations currently available include Search & Recovery, Commercial Diving, Port Security, Offshore, Nuclear Inspection, Work Boat, Potable water, Aquaculture, and Science & Research.

Atlantas Marine is an authorised VideoRay service center, and as such all VideoRay servicing & repair work is undertaken at our UK based workshop. This allows us to offer very quick turn around times and give our customers the support they need. 

High Efficiency Brushless Thrusters

The VideoRay Pro 4’s highly efficient brushless thrusters deliver unparalleled performance and reliability, producing the highest thrust-to-vehicle weight and thrust-to-drag ratios in the industry. Enhanced vertical thrust and pitch-enhanced dive and surface modes get you to and from your working depth quickly, while the ducted hydrodynamic float maximizes efficiency and allows for optimal ROV stabilization.

Motor controllers are tuned for lightning-fast responsiveness. In conjunction with joystick sensitivity and independently adjustable gain these features ensures precision handling and the dexterity to position and hold the ROV exactly where you need it.

Camera Systems

The VideoRay Pro 4 is equipped with a high resolution colour camera, equipped with wide dynamic range and backlight compensation to give you the most detailed pictures even in difficult lighting situations. The camera is optimized for underwater use and offers ultra low-light sensitivity by including automatic or manual switching between colour and black and white modes. There are more than 20 user controllable settings that can be managed from the surface.

Ultra High Intensity LED Lighting

Industry leading LED lighting provides 3,600 lumens of light.

The forward light reflectors have been engineered to distribute the light evenly throughout the camera tilt range. Lights are positioned outside the main pressure hull to provide the greatest separation from the camera.  Separation is extremely important in minimizing backscatter and reflections.

Internal Sensors

The VideoRay Pro 4 includes enhanced navigation features including a 3D Compass and a MEMS Rate GYRO, and a depth sensor with accuracy better than 1 inch allowing very stable auto depth and auto heading modes. 

The VideoRay Pro 4’s internal sensors can detect vital information including temperature, moisture (in the unfortunate event of a leak), and a range of internal diagnostics. This information can be essential in reducing downtime while keeping the mission going.

Ergonomic 12 Button Hand Controller

Intuitive and ergonomic VideoRay controls allow you to pilot the ROV instinctively and comfortably. No specialized training is required for basic operations.

Complete ROV control, including recording of still images and video is available through the hand controller. Additional functions and custom configurations can be added using the programmable feature of the 12-button industrial hand controller.

All components fit neatly in a watertight, rolling Pelican case that fits easily in the trunk of a car or in airline luggage compartments. The Scout ROV system includes a fixed color camera and a 7 inch LCD color display monitor.

An external video monitoring/recording device that has a composite video input is recommended for recording missions.

Consider moving up to the Scout X3 which includes the Tether Deployment System (TDS), an excellent option for quick coiling and recoiling of the tether.
