My name is Arthur ENGASSER. I am an 18-year-old French French student in preparatory class in order to become an engineer. As part of my studies I have to deal with a subject related to the ocean, seek information, conduct experiments in order to provide scientific added value on a defined subject. I became interested in underwater acoustic communication. So that's why I'm contacting you. As one of the first companies to develop the underwater drone, you are probably the most likely to help me guide my research. I would like to learn a little more about the solution you have chosen so that the user can communicate with the drone. I have already understood from your forum that cable is not only used to communicate with the drone but also to power it. However, it seems to me that the cable limits the movements of the drone and therefore the exploration of wrecks for example. So I wonder why you chose to use a cable. If you can provide me with some answers, I would be very grateful. Thank you for reading this post!
