OZD is the only CMAS technical dive center in the south of Thailand and is the technical advisor for TDA technical diving branch.

CMAS technical programs are constructed around the whole CMAS system, so entering a CMAS tec course basicaly requires the diver to be a qualified CMAS diver. CMAS Tec courses follow the same structure as most other agencies to the exeption of the lack of decompression and extend range courses, which are part of the *** star diver course.

Introduce the diver to the techniques involved in diving with nitrox to a limit of 40% oxygen.Make the diver aware of the additional physiological problems encountered when diving with gases other than air. Make the diver aware of the special dive planning procedures appropriate to diving with nitrox. Introduce the diver to the problems of equipment approved for oxygen and procedures for gas mixing. Prepare the diver for the first dives using nitrox, and to lead toward further experience before taking the Advanced Nitrox Diver course.
