Here a video of today's test to 28meters, to check if the network connection to the ROV is really water proof
on the successful test. How did you go about sealing the network cable at the ROV?
As for the audio, might I suggest a video editor? :)
With wind like that I half expected to see one of Theo Jansen's beests sprinting down the shore in the background.
A+ Check one off the list!
