Advanced Recreational Trimix Diver in Indonesia: 2 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 2 publish course prices.
TecDiveTools lists 2 dive centres teaching Advanced Recreational Trimix Diver in Indonesia. 2 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). 2 of these 2 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, 2 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 open-circuit course teaches recreational divers to manage helium-based gas mixtures at greater depths, reducing nitrogen narcosis while maintaining recreational-level decompression procedures and dive planning. You'll learn multi-mix deployment strategies, hyperbaric narcosis avoidance, and stage cylinder management for air/EANx/trimix transitions. This course unlocks deep recreational technical diving and is a gateway to full technical trimix certification for divers seeking to explore the world's deepest recreational dive sites.
