Centres that teach this course
2 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.

Same training under a different agency
30 centres
A separate set of centres, teaching Cavern 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

These centres publish a price for Cavern, 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.

Common questions about ANDI Cavern
How much does ANDI Cavern cost?
Published prices for ANDI Cavern range across 2 centres in the TecDiveTools directory. That is THB 20,000–29,000 (2 centres). Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
How long does ANDI Cavern take?
Between 3 and 4 days, based on the durations 1 centre publishes for it. The time depends on the centre's schedule, weather, and how quickly the required skills are demonstrated — agencies set a minimum number of dives, not a fixed number of days.
What is the equivalent of ANDI Cavern in other agencies?
At the same tier in TecDiveTools' cross-agency comparison: TDI Cavern, RAID Cavern, PSAI Cavern Diver, IANTD Cavern Diver, NSS-CDS Cavern Tech Diver, SSI XR Extended Range Cavern Diving and NSS-CDS Single Tank Cavern Diver. They cover comparable training, but each agency sets its own standards, depth limits and certification card, so they are comparable rather than interchangeable — check which one your next course accepts.
