Twinset Diver in worldwide: 41 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 19 publish course prices.
TecDiveTools lists 41 dive centres teaching Twinset Diver worldwide. 19 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). 25 of these 41 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, 18 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.
