The navigational markers and mooring buoys are made out of environmentaly friendly UV stabilized polyethylene and are filled with CFC-free low absorbing EPS. This helps them keep their buoyancy even after a collision. With buoy lanterns as a speciality NavigationsTeknik offers a wide range of cardinal markers.
