CCR Advanced Recreational Trimix Diver in worldwide: 20 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 13 publish course prices.
TecDiveTools lists 20 dive centres teaching CCR Advanced Recreational Trimix Diver worldwide. 13 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). 13 of these 20 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.

About the course
This rebreather course trains CCR-qualified divers to deploy helium-based mixtures on closed-circuit rebreathers at greater depths (up to 150 fsw), achieving exceptional efficiency and minimal narcosis for deep technical recreational dives through hypoxic bailout and multi-setpoint oxygen management. You'll learn hypoxic loop operation, setpoint transitions across depth, and extended decompression procedures on CCR. This course unlocks highly efficient deep technical recreational diving and bridges toward full technical CCR Trimix certification.
