Technical Cave Diver in worldwide: 46 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 28 publish course prices.
TecDiveTools lists 46 dive centres teaching Technical Cave Diver worldwide. 28 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 30 of these 46 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 25 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

Published prices for IANTD Technical Cave Diver worldwide range across 5 centres in the TecDiveTools directory — roughly US$600 to US$1,800 at current exchange rates. In each centre's own currency: THB 59,000 (3 centres), $600 (1 centre) and €1,000 (1 centre). 4 centres charge by the day instead, which is not comparable with a course total. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
Between 2 and 10 days, based on the durations 6 centres publish for it worldwide. 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.
At the same tier in TecDiveTools' cross-agency comparison, dive centres worldwide also teach TDI Cave Decompression (20), NSS-CDS Tech Nitrox and Cave Decompression Diver (2) and PSAI Cave Decompression Diver (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
