During the TDI Advanced Nitrox course not only will you become proficient with analysing and marking cylinders containing high percentages of oxygen, but you will also work on your overall diving ability. To be able safely to use the full range of Nitrox mixes available to you after certification as an Advanced Nitrox Diver you will need to ensure that you achieve excellent buoyancy control and the ability to maintain this control even if things are going wrong around you.

By working on your buoyancy and trim in full technical diving over the course of 4 dives and 100 minutes bottom time you will finish the course with confidence to maintain safety stops, share gas with another diver and handle failures such as free flowing regulators or leaking hoses.

• Minimum age 18 (15 with parental consent)
