I enlisted drone pilot videographer Riley Goss for help on this one. I knew the water was crystal clear and he would be able to see me underwater from above. I place the fish cam in 15 feet of water or so, in a trench between two outcrops, and then make a couple short dives to adjust it. Best part: the amazing tracking shot @1:10, where you can see what a beautiful underwater playground there is here at the Ledges. (No audio.)
