Technical diving in worldwide: 311 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 85 publish course prices.
TecDiveTools lists 311 dive centres teaching technical diving worldwide. 85 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). 198 of these 311 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, 140 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.

TecDiveTools lists 311 dive centres teaching technical diving worldwide: Mexico (102), United States (66), Philippines (39), Thailand (31), Egypt (30) and Indonesia (24), and 1 more country. The directory is not a census — it lists the centres we have been able to verify, and grows as more are added.
TDI (249), IANTD (74), PADI TecRec (14), GUE (12), NSS-CDS (12), RAID (11), SSI XR (8), ANDI (4), PSAI (1) and UTD (1), counted by how many of the 311 dive centres listed worldwide teach each. 91 teach more than one agency. The agency sets the standards and issues the card; the centre sets the price and schedule. Recreational training (SDI, PADI and SSI) is taught too and is not counted here.
