+Tether somehow came off my BCD and the end of our dive on the La Francesa reef in Cozumel on 8/24/2020. Dive with Martin was our boat. . It was in about 25-30 ft and mostly flat sandy bottom. GoPro Hero5 on a black aluminum tray with a Bigblue video light (Color Blue). There are pictures of my and my wife on it. Will be able to give specifics of most of the photo's and videos..... thanks
