TDI Tech Courses

Techncial Diving International Courses

TDI has an excellent progression of courses to take people from entry to technical diving, through to the most advanced levels. The courses we teach most frequently are detailed below with for most people, the best pathway being :

  • Advanced & Helitrox ( or Decompression Procedures )
  • Trimix Diver
  • Advanced Trimix Diver

At any point along the way you could branch out to include the challenges of Advanced Wreck diving, the use of DPV’s, learn about Gas Blending or move towards Rebreathers. Unless otherwise stated all our course fees include Manuals and Certfication Fees, local boat trips, tank, regulator and backplate/wing bcd’s, and all gas fills except helium. Students need to bring, or rent, their own personal equipment such as wetsuits, mask and fins, gauges etc. Some courses may also be packaged together. If you have questions on any of these, or other courses, please email us at: info@techasia.ph
