TDI TEC Diving

Diving on air has limits. When we dive on air we have to consider nitrogen narcosis and No Decompression Limits (NDL) when planning dives.
Technical diving pushes back the NDL and nitrogen narcosis limits of air.

Technical Diving International is the largest technical diving certification agency in the world and is one of the first agencies to provide training in mixed gas diving and rebreathers, TDI’s professionals are held to the highest standards to ensure quality training throughout the world.

This means that your TDI instructor will have documented his experience and knowledge prior to achieving that rating. TDI is committed in offering the highest quality training supported by the latest materials with the most up to date information and techniques.

From Basic TDI Nitrox Diver to TDI Dive Master Course, Deep Divers offer all levels of Technical Training Courses.

Below you will find brief descriptions and prerequisites of the most followed courses.

But we would be happy to receive an email when you like to find out more about the other courses or have still questions after reading our basic course information.

The TDI Intro to Tech Diving course is the perfect course for divers who have heard about technical diving and want to find out more about this exciting branch of advanced recreational diving.

This course walks students through the special techniques, planning procedures and skills that set technical diving apart from traditional sport diving. It will show them how to improve their dive planning methods, in-water skills and streamline their existing gear configuration, in a non-threatening and fun learning environment.Out of air.

The TDI Nitrox course is an entry level course for divers wishing to utilize enriched air nitrox 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.

The TDI Advanced Nitrox course qualifies divers to use enriched air nitrox from EAN 21 through 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.

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.

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.
