Big Blue Tech – Technical Diving Thailand – Celebrates the graduation of Ash Dunn, Mark Slinn and Adny Cavell from their TDI Decompression Procedures Course conducted over the past few days off the coast of Thailand on and island called Koh Tao

The TDI Decompression Procedures course is best described by the TDI/SDI website as:

The TDI Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal sport diving limits.

This course began before the christmas break with some new skills to help train the students to a level appropriate for entering the next step. The students will start their next course, TDI Extended Range, on our Similans Islands Liveaboard in the new year.

The highlight of the course was the abundant marine life on every dive. With large 2 meter Bull and Gray Reef Sharks around us during all our dives the excitement of diving was forced back into every sense we had. The sharks at Chumphon Pinnacle Dive Site seem to disapear during some months and then come back in large numbers without warning. Sharks can be seen hunting and stalking prey but always keeping a safe distance from divers. This safety is kept in part from the prevention of shark feeding so no shark has associated food with a diver.

All of the students excelled at their skills and conduct in the water and received their certification after completing a written examination.

Below are some pictures from this event. The next open space for this course is in March 2010
