Decompression Specialist in Thailand: 11 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 10 publish course prices.
TecDiveTools lists 11 dive centres teaching Decompression Specialist in Thailand. 10 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). 7 of these 11 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, 7 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.

About the course
This specialized classroom course (no water diving) qualifies divers or professionals to master decompression theory, gas physiology at depth, and the software/algorithm tools used for technical dive planning. It bridges recreational and technical diving knowledge with rigorous decompression science, including dissolved and bubble models, and proficiency with advanced decompression planning software. This theoretical foundation is essential for technical divers planning extreme dives.
Demonstrate mastery of inert gas uptake and elimination, dissolved-gas vs bubble-formation decompression schedules, and proficiency with advanced decompression planning software.
