This not a ROV... in an other word, iBubble looks like the DJI Phantom 4 underwater.
The prototype is a bit slow at the present time. The transmitter is still a bit "huge" but existing technology give a range of 15 miles... 90ft will be enough lOl.
Some options will be available like 2x1000 lumens led light add on, lights will offer an angle capability to avoid back-scattering, especially when shooting in saltwater
