Helitrox CCR Decompression Procedures in worldwide: 54 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 22 publish course prices.
TecDiveTools lists 54 dive centres teaching Helitrox CCR Decompression Procedures worldwide. 22 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). 41 of these 54 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, 35 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 days, based on the durations 1 centre publishes for it worldwide. The time depends on the centre's schedule, weather, and how quickly the required skills are demonstrated — agencies set a minimum number of dives, not a fixed number of days.
At the same tier in TecDiveTools' cross-agency comparison, dive centres worldwide also teach IANTD CCR Advanced Recreational Trimix Diver (20) and SSI XR CCR Extended Range Trimix (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
