Borrowed a GoPro camera to play with so here's a 4 min video of the old bugger doing 30 at Yorkey's FNQ. I only got one good run that day so was lucky to get some video.
Note how blue the water is At 1.05 the Shark bait, a baited hook on a buoy
I'm happy with the quality for the price so will get my own, I know there are better cameras but I think there is only so much video I need of me bouncing around the ocean so no need to spend more
