Advanced Nitrox and Decompression Procedures
Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water longer. The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 45 meters/150 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.
When you book this course, you will receive all the student materials to complete at home, which takes about 10 hours.
An instructor will then reach out to schedule your classroom session and dives.
The course includes gas and 6 dives (3 charters with 2 dives each).
Additional dives are not included but can be arranged separately.
TDI Advanced Nitrox Training at Stuart Scuba
What is TDI Advanced Nitrox?
TDI Advanced Nitrox teaches divers to use enriched air nitrox from EAN21 through EAN100 within their certification limits. It is a foundation course for technical divers and future SCR or CCR divers.
Is Advanced Nitrox taught alone?
At Stuart Scuba, Advanced Nitrox is normally taught with TDI Decompression Procedures or TDI Helitrox. This lets equipment, dive planning, gas selection, skills, and emergency procedures work together as one technical-diving program.
What is the difference?
Advanced Nitrox covers higher-oxygen gases and oxygen-exposure management. Decompression Procedures adds staged-decompression planning and execution. Helitrox adds helium-based breathing mixtures to reduce nitrogen exposure on deeper dives.
What will I learn?
Training covers oxygen physiology, maximum operating depth, gas analysis, gas planning, equipment configuration, team procedures, buoyancy, trim, propulsion, shutdowns, gas sharing, decompression-gas handling, DSMB deployment, and dive planning.
How much study is required?
After booking, you will receive materials to complete at home. Plan on 10 hours of independent study. Your instructor will contact you to schedule class and training dives.
What is included?
The course includes breathing gas and six training dives over three two-dive charters. Equipment needs depend on your course combination. Stuart Scuba will review your equipment and explain any rental or purchase requirements.
How deep will I dive?
Depth depends on the course combination, certifications, gas plan, conditions, and performance. Training may progress to 45 meters/150 feet when allowed by standards. Performance and judgment matter.
