TDI Technical Courses

Nitrox is, for most divers, the first step into technical diving, but it has also become very popular amongst sport divers, so TDI Advanced Nitrox and Decompression Procedures are often a great start. Advanced Nitrox and Decompression Procedures form the foundation of technical diving for all other courses.
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.
