CCR Trimix Diver in the United States: 4 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 1 publish course prices.
TecDiveTools lists 4 dive centres teaching CCR Trimix Diver in the United States. 1 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). 4 of these 4 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, 4 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 full technical certification qualifies Normoxic Trimix-trained divers to deploy hypoxic and normoxic trimix mixtures on closed-circuit rebreathers with multi-setpoint strategies across depths to 330 fsw (100 msw). It enables the most efficient technical diving possible at intermediate and deep depths through oxygen partial-pressure management, forming the foundation for expedition-level CCR diving.
Demonstrate mastery of hypoxic and normoxic loop operation, multi-depth setpoint transitions, comprehensive stage management, and advanced decompression strategies on CCR.
The centres listed above teach IANTD CCR Trimix Diver in United States. 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.
4 dive centres on TecDiveTools teach IANTD CCR Trimix Diver in the United States: North Florida Cave Country (2), Florida West Coast (Tampa Bay) (1) and Southeast Florida (1). Each is listed above.
Rebreathers are common in Florida's cave community for long penetrations, and the springs' constant temperature and depth make them a practical place to build hours on a unit.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in the United States also teach TDI Advanced Mixed Gas CCR (11). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
