TDI Advanced Nitrox & Decompression Procedures Course

The ANDP course is the first step into multiple gas diving. The 2 courses can be taken separately, but they compliment each other so well, they really should be one single course.

During this course you will develop all the skills to safely conduct open circuit dives with staged decompression, to a maximum of 45m, using an enriched nitrox mix (50%) to accelerate your decompression phase.

As this course is a technical dive course, pushing you beyond the boundaries of the recreational dive world, we aim to cultivate and grow a technical mindset in our student divers. We do not believe tech diving is a weekend specialty course, and our instructors are regularly tech diving, locally and internationally, and keeping abreast with the latest changes and improvements in the tech diving world.

While it is not a hard pre-requisite, we firmly believe that this course requires competency and familiarity with diving with multiple cylinders, either in the backmount twin configuration, or our preferred configuration of Sidemount. As such, if you have not already completed one of these courses, then we strongly recommend a sidemount course be completed well before you consider this course.

As a technical diver, it is also imperative that you are intimately familiar with your dive gear, and as such it is practically essential that you own your own gear for this course. Please feel free to contact us prior to making any purchases, our tech instructors are always willing to offer their time and advice when it comes to gear selection. They have dived with and used a number of different brands and configurations, and will be able to provide you with detailed recommendations.

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? 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 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression 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.

Combining gasses higher than 40% and decompression theory is what this combination offer. The course examines the theory, methods and procedures of planned stage decompression diving to a depth of 45 meters.
