Advanced Trimix in the Philippines: 11 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 1 publish course prices.
TecDiveTools lists 11 dive centres teaching Advanced Trimix in the Philippines. 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). 9 of these 11 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
Advanced technical diving course extending trimix diving into hypoxic gas territory at depths exceeding 70m/230ft. Teaches hypoxic gas planning, extended decompression management with multiple gases, and equipment redundancy required at extreme depths. Represents the top of open-circuit depth progression before rebreather training.
Minimum 4 dives with 100 minutes accumulated bottom time. At least 2 dives deeper than 70m/230ft. In-water skills: gas management at extreme depth, multi-stage decompression execution, buoyancy control at pressure, emergency procedures with stage cylinders. Competency in hypoxic gas calculations and extended decompression gas switching.
The centres listed above teach TDI Advanced Trimix in Philippines. 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.
11 dive centres on TecDiveTools teach TDI Advanced Trimix in the Philippines: Moalboal (2), Puerto Galera (2), Anilao (1), Cebu (1), Dauin (1) and Malapascua (1), and 3 more. Each is listed above.
Walls off Moalboal and the drop-off beyond Malapascua's Monad Shoal reach technical depths close to shore, and Coron's Irako gives deep decompression dives a wreck to work on.
