Advanced Trimix in Koh Tao: 1 dive centre on TecDiveTools, with agencies, courses taught and a summary of what students say.
TecDiveTools lists 1 dive centre teaching Advanced Trimix in Koh Tao, Thailand.
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). 0 of these 1 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, 0 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.
