Helitrox CCR Decompression Procedures in Mexico: 6 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 3 publish course prices.
TecDiveTools lists 6 dive centres teaching Helitrox CCR Decompression Procedures in Mexico. 3 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). 5 of these 6 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, 6 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
Extends Helitrox CCR diving into staged decompression using helium-diluted mix (up to 35% helium, up to 100% oxygen for decompression) to 45m/150ft. Teaches decompression gas planning and bailout procedures specific to helium-diluent rebreathers alongside core CCR decompression skills. Designed for divers on TDI's advanced mixed-gas CCR track seeking to extend Helitrox diving into mandatory-stop territory. Prerequisite requires at least 5 logged staged decompression dives to 30m/100ft.
Divers must perform decompression-specific drills, demonstrate helium-decompression gas planning, execute emergency procedures, manage deco obligations, and maintain buoyancy/trim in staged decompression dives to 30m minimum depth.
6 dive centres on TecDiveTools teach TDI Helitrox CCR Decompression Procedures in Mexico: Tulum (4), Mexico City (1) and Playa del Carmen (1). Each is listed above.
Long cave penetrations are where rebreathers pay off, and the Yucatán has one of the largest rebreather cave-diving communities anywhere, which makes unit-specific training and support easier to find than in most places.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in Mexico also teach IANTD CCR Advanced Recreational Trimix Diver (4). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
The centres listed above teach TDI Helitrox CCR Decompression Procedures in 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.
