TDI Advanced Nitrox Diver

dptscuba tech diver

The TDI Advanced Nitrox Diver course teaches divers about the benefits and hazards of diving with gas mixes containing up to 100% oxygen to a maximum depth of 40m. It is a foundation technical diving course and is most commonly taught in combination with the TDI Decompression Procedures course. It is also a prerequisite course for CCR training.

Prerequisites:

  • Minimum age 18, 15 with parental consent
  • Minimum certification of TDI Nitrox Diver or equivalent
  • Proof of 25 logged open water dives (bare minimum, I would highly recommend closer to 100 dives)

Course Duration:

As a stand alone course, Advanced Nitrox requires 3 full days

  • Day 1: Theory review, gear appraisal and dry skill session (9-5pm)
  • Day 2: 2 shore dives focussing on skill development (9-5pm)
  • Day 3: 2 boat dives to a maximum depth of 40m (dependent on boat schedule)

When taught in combination with decompression procedures, 4 full days are required, or 3 full days and 2 half days for decompression dives (dependent on boat schedule)

  • Day 1: Theory review, gear appraisal and dry skill session (9-5pm)
  • Day 2: 2 dives focussing on skill development (9-5pm)
  • Day 3: 2 dives to a maximum depth of 40m, no decompression (dependent on boat schedule)
  • Day 4: 1 or 2 dives to a maximum depth of 45m, including staged decompression (dependent on boat schedule)
  • Day 5: 1 dive to a maximum depth of 45m, including staged decompression (dependent on boat schedule)

Course Content:

Advanced Nitrox picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including:

  • Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
  • Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
  • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen

Training and certification:

Upon successful completion of this course, you will be able to plan dives using gas containing up to 100% oxygen, to a maximum depth of 40m so long as:

  • The diving activities approximate those of training
  • The areas of activities approximate those of training
  • Environmental conditions approximate those of training

This course is also a prerequisite to enrol in the TDI Decompression Procedures course and the TDI JJ-CCR Level 1 course.

As with all courses at DPT Scuba, training is purchased, but certification is earned. This means you must meet ALL the required skills & standards before you will receive a certification card. Additional training to meet these requirements will incur additional costs.

Certification Requirements:

  • Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
  • Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
  • Demonstrate the ability to manage free flow from primary regulator in controlled fashion, shut down cycle, and switch to back up regulator
  • Conduct appropriate safety stop while maintaining neutral buoyancy
  • Demonstrate the ability to share air with buddy as both recipient and donor in a controlled manner while maintaining position in the water column
  • Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
  • Demonstrate proper stress analysis with self and dive buddy
  • Satisfactorily complete the TDI Advanced Nitrox course and written examination
  • Complete all open water requirements safely and efficiently
  • Demonstrate mature, sound judgment concerning dive planning and execution
