This is where our new 50 kg electric jet-powered direction finder drone is now being used. It can travel for up to 6 hours at 4 knots on one charge. And with a draft of just 20 cm and a length of 1.65 meters, it can get into the smallest corners. It can actually do everything that a large sounding vessel can do. In addition to classic underwater sounding with the multibeam echo sounder, it also has a special type of camera above water with which a precise 3D laser scan, e.g. of banks and quay walls, can be created.
The small and quiet drone is also ideal for water areas that are not actually used by ships, such as the Alte Süderelbe or the new Kreetsand shallow water area.
