TDI
Who is TDI?
TDI is the largest technical certification agency in the world. As one of the first agencies to provide training in mixed gas diving and rebreathers, TDI is seen as an innovator of new diving techniques and programs which previously were not available to the general public. Training with TDI has provided divers with the opportunity to see such wrecks as the Andrea Doria, Luisitania and the Prince of Wales. TDI divers have explored underwater caves in Spain, Australia and Mexico and assisted as support divers on world record freedives done in the Red Sea.



TDI’s professionals are held to the highest standard to ensure quality training throughout the world. This means that as a diver taking a TDI course, your instructor will have documented his experience and knowledge prior to achieving that rating. As an instructor candidate taking a TDI course, your TDI instructor trainer will have gone through the paces to achieve the highest level of training that TDI offers.
TDI is committed to offering the highest quality training supported by the latest materials with the most up to date information and techniques. TDI’s materials are written by authors that acutely conduct the type of diving they are writing about. Those same materials are update as technology and equipment change.

Question: What is technical diving?
Answer; All non commercial diving is categorized as recreational and within recreational diving there is sport and technical. Sport diving includes your open water certification, advanced scuba diver, and many other specialty course. Technical diving picks up where sport diving ends generally at nitrox (a breathing gas with oxygen levels greater than 21 percent).
Question: What is my first step into technical diving?
Answer; Nitrox is most divers first step into technical but it has also become very popular amongst sport divers so TDI Advanced Nitrox and Decompression Procedures would be a great start. Advanced Nitrox and Decompression Procedures for the foundation of technical diving all other course will build on the knowledge and skills learned during these courses.
Question: Do I have to go deep for technical diving?
Answer; No. Although technical diving is commonly thought of as deep, there are a lot of courses that stay within the sport diving limits (40 m / 130 feet) such as Advanced Nitrox, Semi Closed Circuit Rebreather (SCR) and Closed Circuit Rebreather (CCR) and Advanced Wreck to name a few.
Question: Will technical diving allow me to go deeper?
Answer; yes. TDI has course curriculums that take you as deep as 100 m / 330 feet and do so in a manner that each course builds on the last and each course takes you a little deeper. By receiving training in this manner not only are your skills and knowledge increasing but so is your comfort level.
