The hammerhead video is lame. My main focus was the stills and kept taking it down since I felt I was struggling getting a decent shot. I only took the video down 2 time for hammerheads. At Alycon had great viz and hundreds of hammerheads. Raise the video up to shoot and the housing (Ikelite) is a total fog out, DOOOOHHHHHHH! We had gone from the surface temp of 75 to a thermo cline of about 65 and it was to much for my little desiccate pack.
