Eliminate data uncertainty with high-quality seabed imaging
ScanFish Tropheus is a terrain-following ROTV especially designed for UXO detection that eliminates data uncertainty with high-quality seabed imaging
Optimal side-scan sonar positioning
… through an intelligent ROTV functioning as depressorAccurate real-time data
… through continuous data acquisition close to the seabedEfficient operations that do not forgo safety
… through the possibility of using an unmanned vessel to tow the ROTVMonitoring and complete control of the vehicle
… through the user-friendly ScanFish III Flight softwareA long service life
… through quality materialsReduced risk of the ROTV suffering damages
… through robust design and a storage cradle -
Continuous acquisition of accurate and comprehensive data
ScanFish Rocio's pattern in the water column is easily adjusted to ensure well-founded results of the survey task at hand.
Continuous acquisition of accurate and comprehensive data
The intelligent control of the ScanFish Tropheus ensures that the ROTV together with the side-scan sonar mounted on the underside maintain a constant, fixed altitude in proportion to the seabed – and far closer than solutions without a depressor.
Add to this a high tow speed of up to 10 knots and the fact that the ScanFish Tropheus allows for continuous data acquisition, you are ensured more accurate and comprehensive data and thus extensively detailed images of any potential UXO targets.
It is possible to set the ScanFish ROTV to operate at a fixed height from the seabed via the ScanFish Flight software

User-friendly control and monitoring software solution
All ScanFish models come with the ScanFish Flight software, which is an easy-to-use software system allowing for control and monitoring of the ROTV.
User-friendly control and monitoring software solution
All ScanFish models come with the ScanFish III Flight software, which is an easy-to-use software system allowing for control and monitoring of the ROTV.
Controlling the ROTV's movements in ScanFish III Flight software
Only a minimum of training is required to prepare the crew to operate the ROTV, which means you will be ready to set sail within a short period of time. Moreover, there is no risk of wasting time on difficulties resulting from a complicated software user interface.
Via the intuitive interface of ScanFish III Flight, you are in complete control of the position of the ROTV by defining its height compared to the seabed. At the same time, you can monitor its position in the water, and an alert panel will warn you of any irregularities.
ScanFish III Flight in action
On-site calibration
A pre-flight feature allows for testing and calibration of the ScanFish ROTV on-site prior to deployment, promising you the highest possible performance and data quality.
Recording of flight data
Acquired ROTV data can be analysed by means of a flight recording feature. It enables you to play back all flights and, for example, quickly locate the cause of any irregularities, thus enhancing the quality of your results and saving survey time.
Automatic control of winch
ScanFish III Flight can be set up to control the winch towing the ScanFish ROTV, thereby ensuring an optimal cable length adjusted to the movements of the ROTV. This is especially relevant for the ScanFish Konia and ScanFish Rocio models.

Robust product with a long service life
The practical design of the ScanFish models makes them so robust that they can be deployed in rough weather.
Robust product with a long service life
Quality materials and easily replaced wear parts characterise the ScanFish III range and contribute to a high ROI through a long service life
The practical design of the ScanFish III models makes them so robust that they can be deployed in rough weather. This saves time as the risk of downtime is vastly reduced. Two side plates with bars, which also function as handles, protect the body and facilitate handling, thus reducing the risks posed to the ROTV in the water and ensuring the safety of the crew during deployment and recovery.
