See the Donut testing of the new Geo Ranger in the videolink below. This hydrographic research vessel of Niestern Sander has a high maneuverability. This vessel contains Veth Propulsion by Twin Disc, Inc. thrusters; two VL-400 semi-integrated L-drives and two tunnel thrusters with special propeller design. This design ensures low noise reduction and less vibration so that critical underwater measurements can be carried out without problems.
