TDI Underwater Cave Surveying in worldwide: 13 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 8 publish course prices.
TecDiveTools lists 13 dive centres teaching TDI Underwater Cave Surveying worldwide. 8 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). 12 of these 13 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, 11 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.

This foundational survey course is for Full Cave Divers seeking to contribute to cave documentation, exploration records, or conservation projects. Training covers survey methodology, data collection using line, compass, and depth instruments, and the process of converting raw underwater measurements into usable cave maps suitable for expedition planning or publication.
Students complete 2+ cave survey dives of 60+ minutes each, demonstrating mastery of: underwater survey methodology and data collection, compass and line measurement techniques, depth recording under task-loading, emergency procedures during survey work, proper instrument handling, and accurate field note compilation for map construction.
