Open Circuit

TDI Open Circuit Technical Diving Courses



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 15 years and wholeheartedly agree with their philosophy. We currently employ two Instructor trainers and 6 technical instructors.
