Easy deployment and operation with wide and dense coverage
The ScanFish Katria ROTV and four magnetometers are easy to deploy with an A-frame and operate in the ScanFish Flight software.

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

High-quality magnetometers
The magnetometer type included in the ScanFish Katria is the Geometrics G-882 Marine Magnetometer.
When only the best magnetometers are good enough
Magnetometer quality and performance are key to successful subsea surveys
Therefore, the magnetometer type included in the ScanFish Katria is the Geometrics G-882 Marine Magnetometer. This is a high-end yet low-cost solution and the most used in the industry, and a perfect fit for subsea UXO detection.

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.

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 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 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 range and contribute to a high ROI through a long service life
The practical design of the ScanFish 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.
