Imagegear, absolutely no idea what it is but it seems fairly constant judging by this link:-
- well, at least while this sequence was recorded. Your clip appears to the same as the 0:25 - 0:28 point in my link and, at 0:14, the flow appears to stop for a second or so. Rest of the time it seems fairly constant. Someone swabbing something down? They do whatever "swabbing" is in the Navy I understand!!
As I say, absolutely no idea what is actually causing it!
H 'n' H is clueless .... again!
