All About TDI Courses at Tech AsiaWhat you need to know

TDI has a great progression of courses to take you from entry to technical diving through to the most advanced levels. 

The TDI Intro to Tech course has trememdous value to most people starting out. From this platform there is generally a three step pathway through the deeper levels of diving :

  • TDI Advanced Nitrox and Decompression Procedures, or Advanced Nitrox and Helitrox combined.
  • TDI Trimix Diver
  • TDI Advanced Trimix Diver

Along the way you can branch out into specialized areas that interest you, be it DPV Diving, Advanced Wreck, Sidemount, or maybe Gas Blending. We also train Instructors. Have a look at the Flow Chart for ideas.

The Learning Materials You Need

Coming soon are pdf versions of some manuals which will also be included for download with the eLearning option.

Please note that eLearning does NOT replace the instructor presentations in the course. It allows you, like reading the manual, to be better prepared on arrival. If opting for eLearning we will issue the instructions and access codes upon receipt of a small deposit.
