TDI Nitrox course is an entry level course for divers wishing to utilize enriched air nitrox (EAN) as a breathing gas. Little else has impacted recreational diving more than the introduction of nitrox, allowing more time underwater. During this course, you will learn the benefits, hazards and proper procedures for diving with EAN 22 to EAN 40. Your TDI Instructor will also cover.

• Equipment considerations
• Cylinder labelling
• Analysing of Nitrox

Qualifications of Graduates
Upon successful completion of this course graduates may engage in diving activities utilizing EAN-22 to EAN-40.

Graduates would be qualified to enrol in:

• TDI Advanced Nitrox Course.
• TDI Decompression Procedures Course.
• TDI Semi-closed Rebreather Course.

The student must:

• Be a minimum age of fifteen (15).
• Have a Minimum certification of Open Water Diver.

Course Structure and Duration
1 day course covers

• History of Enriched Air Nitrox (EAN)
• Physiology
• Physics
• Equipment Considerations
• Dive Tables
• Dive Computers

• Exam

COST: $329

The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox (EAN), from EAN 21 through to EAN 100 to a depth of 40 metres/130 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. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like:

• Equipment requirements
• Dive planning
• Oxygen tracking
• Blending methods

You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know.

As sport divers, planned decompression is not something that we do or have been taught. The TDI Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal sport diving limits. Your TDI Instructor will provide you with valuable information and skills, among the topics covered are:

• Kit set-up
• Equipment requirements
• Decompression techniques
• Decompression breathing gases
• Gas management
• Contingency planning

The TDI Decompressions Procedures course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels. Some of the materials you will be using include the TDI Divers Guide to Decompression Procedures, US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage).

Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m/180 feet. You won’t have to miss those dives. The Extended Range course will cover topics and skills such as:

• Equipment requirements and configuration
• Decompression options
• Use of surface marker buoys
• Buddy rescue
• Narcosis checks and management

Materials for this course include the TDI Extended Range Diving Manual and the US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage).

The TDI Advanced Wreck course is the next step for any diver that has taken a wreck diver course. During this course, your TDI Instructor will teach you the proper techniques for locating and planning a penetration dive. The Advanced Wreck course is commonly taught with other popular TDI course such as advanced nitrox, decompression procedures, extended range, closed circuit rebreather, and trimix. The course covers topics and skills like:

• Use of guidelines
• Overhead emergency procedures
• Redundant equipment requirements
• Locating and identifying wrecks
• Hazards of wreck diving
• Surveying of wrecks

The TDI Advanced Wreck Diving manual covers all the most commonly used wreck diving techniques in cold and warm water. The manual also covers team diving techniques and preservation of wrecks.
