Here at Dive Spear and Sport, we combine the TDI Advanced Nitrox and TDI Decompression Procedures Courses into one program. These two courses form the foundation of your technical training and qualify divers with standard open-circuit SCUBA equipment to dive to 45m and complete dives with mandatory decompression stop requirements. In addition, you will be certified to use enriched air nitrox, from 41% – 100% O2.


A pathway to deeper, darker things beyond recreational limits, this program is for those who are interested in extending their bottom time and looking to expand their diving knowledge surrounding decompression theory and techniques.
