Decompression Procedures in Tulum: 10 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 6 publish course prices.
TecDiveTools lists 10 dive centres teaching Decompression Procedures in Tulum, Mexico. 6 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). 10 of these 10 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, 10 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
Decompression Procedures is the foundational staged-decompression course: planning and running dives with a dedicated deco gas and mandatory stops, on open circuit, to a maximum depth of 45m/150ft over 4 dives. It teaches gas planning for a single decompression gas, in-water discipline for controlled ascents, and the contingency thinking a no-immediate-surfacing dive requires. It's for Advanced Nitrox divers ready to move from no-decompression technical diving into real staged decompression — the gateway course into TDI's deeper technical progression (Extended Range, Trimix, and most CCR decompression tracks all build on it). It's usually taken right after or alongside Advanced Nitrox, since the two share overlapping dive requirements.
The centres listed above teach TDI Decompression Procedures in Tulum, Mexico. Requirements are set by the agency, not the centre, so they are the same wherever you train — what differs is price, class size and how much diving is included.
