Advanced EANx Nitrox Diver
This open-circuit course extends nitrox diving to greater depths, teaching mix selection and oxygen toxicity management for deeper recreational and technical dives using enriched air blends up to 150 fsw. You'll master accelerated decompression procedures, extended bottom times at depth, and nitrogen narcosis management when combining enhanced oxygen mixtures with greater depths. This course bridges toward technical trimix diving and is essential for divers planning deep expeditions who want to optimize air consumption and decompression obligations.
Centres that teach this course
15 dive centres in the directory publish a price for this exact certification, checked Sep 2026. Each centre's own wording is shown beneath its name. Ranges cover whole-course prices only — where a centre charges per day or per dive, its rate is listed separately below, since a daily figure is not comparable with a course total.

28 centres
A separate set of centres, teaching Advanced Nitrox / Decompression Procedures under a different agency. These are not the same certification — the standards and the card differ — but they cover the same depth and scope, which is why centres price them alike. Every row here names whose rating it is, and none of them is counted above.

Same tier, agency not stated
19 centres
These centres publish a price for Advanced Nitrox / Decompression Procedures, but their own wording does not say which agency's certification it buys — many teach several and name the card only once you enquire, and some price one course for either agency. The figure is comparable; the certification is not identified, so we do not guess at one.

These prices are not like-for-like. Two centres can charge very differently for the same certification because they include different things. One price may cover twinsets, stages, deco gas and cylinder rental for every training dive, a dedicated classroom for the theory, boat or transport to the site, and the agency's registration and materials; another may be tuition only, with all of that charged separately — or the other way round, with a centre bundling in extras the first leaves out. Class size, whether the course is one-to-one, and how many days are allowed for it move the figure too. Check what each centre's price includes before comparing them, and confirm with the centre before booking.
Consumables are usually extra. Sorb, helium, O₂ and other fills, park and cenote fees, certification fees and rental are commonly charged on top.
Packages combining several certifications, upgrades from an existing one, and open-ended day rates are excluded — none of them is the standalone price of this course, and including them would move the figures away from what a new student can actually book.
