Hi,
another two vehicles I saw at the Boot fair in Duesseldorf (quite large diving, yachting and outdoor water sports fair).
Ibubble probably some of you already know ( https://ibubble.camera/ )
Interesting to me was to see their recent (and presumably last) prototype being quite large (7kg) and using 7 ! BR T200 thrusters… More a BlueROV size vehicle now compare to the small diver gadget proposed in the beginning…
And a new vehicle of a Chinese Company: Fifish (http://www.qysea.com/index.html)
Powervision was also there, but that I covered in the CES Post
