Intelligent wide-sweep ROTV for magnetometer surveys

The ScanFish Katria is an intelligent wide-sweep remotely operated towed vehicle (ROTV) solution for time-efficient magnetometer surveys.

As it comes with high-sensitivity magnetometers for maximum target detection efficiency, it is an effective tool for detection of sub-bottom magnetic anomalies. If you wish to connect your own magnetometers, the ScanFish Katria is also available for purchase without magnetometers.

Please note: The webshop price is including magnetometers and excluding shipping fee. An EIVA employee will contact you when we receive your request to finalise all details.

    Deployment of the ScanFish Katria ROTV

    Wide and dense coverage at a fixed height

    The terrain-following operation mode of the intelligent ROTV ensures that it maintains a fixed height as close to the seabed as possible, depending on the topography. This equals high-quality data.

    The horizontal array of underwater magnetometers enables you to cover a larger survey area in less time and ensures dense coverage, translating into better indication of signal strength and origin in one sweep.

    Terrain-following mode of the ScanFish Katria ROTV

    The ScanFish Katria ROTV can be set to automatically follow the seabed in the ScanFish Flight software.

  • High-quality magnetometers

    Controlling the ROTV's movements in ScanFish III Fligh software

    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.

    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

    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.
