Advanced Nitrox + Decompression Procedures (ANDP)

The two halves of entry-level staged decompression, taught back to back.

The most widely sold bundle in the directory and the only one found in every priced country. Most centres teach and charge for advanced nitrox and decompression procedures as one course; the shops that price the halves separately are the outliers. It ends at 45 m with a single decompression gas, and it is the gateway to extended range, trimix and most CCR decompression tracks.

Sold by 19 centres in the directory across Malta, Egypt, Mexico, United States, Thailand, Philippines, Indonesia.

Centres that sell this package

19 dive centres in the directory publish a price for this bundle, 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.

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.

Only rows whose own wording says they bundle these certifications are listed. Upgrades from an existing rating, wider bundles that add a further level, and open-ended day rates are excluded, since none of them is the price of this package.
