The THURN USV Profiler System provides all the tools for your USV sub bottom requirements. Supplied with a GeoAcoustics GeoPulse compact and an SBG INS/positioning sensor all of which come fully integrated. The system was designed to enable remote surveys, keeping people out of the water and minimising risk.

Thus decreasing survey time and enabling surveys in previously inaccessible and dangerous waters. With easy to use industry standard software options this will help solve your hydrographic and survey safety problems. The software will track and display the position of the USV in real-time, with a real-time data feed option.
