What could a diver see? - Ultrasound under water

Have you ever opened your eyes while swimming underwater in Lake Balaton? If so, you know there's not much to see. Now imagine that this is how you, as a diver, should help the passengers of a sunken ship on the Danube. We are trying to find a solution to this problem with the help of sonar images of ships and the use of VR glasses.

Try to find our sunken small boat with the help of the ultrasound device!
