Intro to Tech teaches you the fundamentals of technical diving, starting with: twinset, trim and propulsion The course focuses on perfecting buoyancy and fining techniques as without those – your life as a technical diver just got harder. Starting with the basics, we can then progress to skills being performed neutrally buoyant and in trim.


Nitrox diver qualifies you to use Nitrox mixtures containing 22-40% O2 to a maximum depth of 40m. TDI Nitrox course is an entry level course where you will learn the benefits, hazards and proper procedures for diving with EAN 22 to EAN 40. It can be used to extend bottom time, depending on gas consumption.


Advanced Nitrox is used to expand your time underwater. The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox through to 100% Oxygen within your current certification level to a maximum depth of 40 metres during dives that do not require staged decompression. We often teach it with the TDI Decompression Procedures course.


The deco pro course is the foundation course for all stage decompression diving. As recreational divers planned decompression is not something that we do or have been taught; the TDI Deco Pro course prepares you for just this. Among the topics covered are: deco techniques, deco breathing gases, gas management, contingency planning, problem solving procedures.


Extended range is the pinnacle of Air/Nitrox diving. This challenging course teaches you the proper techniques, procedures, risks and hazards to plan and perform accelerated staged decompression dives to 55m. The course also covers advanced diving physics, physiology and decompression theory to give a full understanding of all aspects of diving utilising air and Nitrox.


Entry level trimix is the first step into helium based diving. Helium based diving reduces the effects of narcosis, allowing you to dive at deeper depths and qualifying you to utilise non hypoxic (minimum 18% O2) trimix mixtures to perform accelerated staged decompression dives to 60m and finally dive the Arch at the Blue Hole.


Advanced Tmx qualifies you to use helium to do accelerated staged deco dives to a max of 100m. It is the top level of training for the Open Circuit diver and is perhaps one of the most informative and challenging courses resulting in you being among some of the most elite divers below the water.


TDI Gas blender/Advanced Gas blender course provides the training required to allow you to competently and safely blend Nitrox and Trimix After covering academic subjects including responsibilities of the gas blender, oxygen handling and gas production equipment and oxygen analyzing, you will demonstrate proficiency in blending nitrox.
