Almitch, what vis was it like for you in neptune fansea aka gorgonian patch. On that dive we must have had 40m+ prob as it was a channel. But yes all others were 10m average in sth and 15m average in north.
We did do a dive down in the South called Gorgoninan ...something which was in a narrowish channel between two islands but the viz was pretty average there. Not sure if its the same dive site you are talking about. Definitely never had any 40m+ viz dives... I definitely would remember that.
