Thank you for your kind words! Shipping to customers is always great.
Your questions about onboard position and acoustic communication are very interesting. As you have seen in the YouTube video, we made a “proof of concept” drone which we controlled without a tether. Currently we are fully focused and commited to the Underwater GPS solution and will continue to refine this. We are constantly evaluating market needs and applying this to our roadmap. At the moment we are not able to communicate our roadmap publicly, but your interests are well received!
