NEW PADI Tec Rec Course Update

In November 2023 PADI launched a complete revamp of all their Technical Diving Programs and Courses. The core courses Tec 40, Tec 45 & Tec 50 have been completely rewritten with the most up to date training methodology using the latest internationally recognized research, Diving Science and Technical Diving practices.

For example as a result of the new diving science around Gas Density there is now an option to train and qualify to use trimix as a gas option. This is available on all three core courses beginning at 40m with the Tec 40 Trimix certification option.

Tech Dive Asia is the only training facility in Phuket to offer both diver level and Instructor level Technical Diving Courses under the new PADI Tec Rec format.

Latest Training Materials

The new PADI courses additionally include eLearning availability at all levels with the same platform as recreational courses allowing an easy transition for students moving from recreational diving to Technical Diving.

Although there is an introduction to dive tables all the dive planning is now done on software without the need for complicated calculations. Therefore the theory time previously taken on planing theoretical dives can now be focused on the latest gas density and gradient factor theory.

Both the new student materials and the instructor materials are arguably some of the best materials currently available in the Technical Diver training space.
