Fantastic 55m this morning as part of the IANTD Normoxic Trimix MkVI CCR Diver course at Drop Off. Had a MolaMola, an awesome encounter with a thresher shark which was flanking a school of big eye jack’s and white tip and black tip reef sharks. Shame we had to bail-out. would have been nice to stay and watch a bit longer. Another reason Bali is such a toptastic Tek destination.
