Advanced Trimix school Hydra 2006

Article: George Petrou

Hellas Underwater Explorers / George Petrou organized and held an Advanced Trimix Diver school in the summer of 2006 with certification from the TDI organization. Trainees were Nasos Zervopoulos, Kotsifas Ioannis, Agapakis L. The dives took place in the wonderful waters of Hydra. Maximum school depth was 100 meters. The last certification dive had a wonderful surprise in store for us as we reached its deepest point and met 4 large gray rays which calmly swam away from us towards the deep blue. The participants had an excellent performance.
