Technical Diving International (TDI) was formed in 1994 by some of diving’s most experienced instructors. The aim was to bring technical diving applications to a wider audience. TDI’s training materials have become known as the best in the industry, with the most professional resources available. Most importantly, they have the best safety record of all training agencies and have become the largest, specialised dive agency in the world.
TDI instructors maintain the highest levels of professionalism, standards and quality instruction. This ensures that certification is earned so that students walk away proud and competent technical divers.
Blue Marlin Tech have been a TDI technical facility for over 18 years and wholeheartedly agree with their philosophy. We currently employ two instructor trainers, two technical instructors and 1 technical guide.

decompression.
Often taught together with the Decompression Procedures course, this is the foundation of your technical diving career when you choose the classic technical divers Twin Tank or Sidemount option. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for Semi-Closed Rebreather (SCR)or Closed-Circuit Rebreather (CCR) divers.

requirements and configuration, decompression options, use and deployment of surface markers,
buddy rescue and narcosis checks and management.
Upon successful completion of the course, divers will be certified to plan and execute deep
air decompression dives to a maximum depth of 55m with the use of up to two
decompression/travel gases.

that wreck
that is part of history or that cave system that you have read so much about. One of the major
limiting
factors of going deeper is narcosis; the TDI Trimix Diver course provides the training
required to competently
and safely utilize breathing gases containing helium for dives that require staged
decompression and
how to minimize the effects of narcosis by adding helium to offset the nitrogen in your
breathing gas.
Students must show exemplary in water skills and show good mental and physical fitness.
