Normoxic Trimix Diver in Indonesia: 1 dive centre on TecDiveTools, with agencies, courses taught and a summary of what students say. 1 publish course prices.
TecDiveTools lists 1 dive centre teaching Normoxic Trimix Diver in Indonesia. 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). 1 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, 1 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
Normoxic Trimix is a technical mixed-gas certification designed to extend depth range to 132–200 fsw (40–60 msw) while managing nitrogen narcosis through trimix theory. This course trains divers in gas blending basics, narcosis mitigation, decompression procedures using nitrox decompression gases, and safe single-gas-switch profiles. The qualification bridges recreational and advanced technical diving, unlocking deeper technical wreck and cave progressions.
Demonstrate safe trimix gas blending, narcosis management through depth planning, decompression gas selection and switching, gas management on technical dives, and emergency procedures specific to mixed-gas technical profiles.

At the same tier in TecDiveTools' cross-agency comparison, dive centres in Indonesia also teach TDI Trimix (6), RAID Normoxic Decompression (1) and PADI TecRec Tec Trimix 65 (1).
