Advanced Nitrox in Indonesia: 21 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 7 publish course prices.
TecDiveTools lists 21 dive centres teaching Advanced Nitrox in Indonesia. 7 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). 12 of these 21 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, 9 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
Technical diving course teaching advanced nitrox diving from EAN-21 to 100% oxygen at depths to 40m/130ft. Teaches gas planning, oxygen exposure management, gas switching procedures, and multi-gas dive planning for technical diving without staged decompression. Gateway to deeper TDI technical courses.
Land drills: oxygen analyzer use, dive planning with CNS/MOD calculations, nitrox computer setup. Pre-dive: START procedure (S-drill, Team checks, Air matching, Route, Tables). In-water: buoyancy control, air sharing, free-flow management, safety stops. Minimum 4 dives with 100 minutes accumulated bottom time, max depth 40m/130ft.
The centres listed above teach TDI Advanced Nitrox in Indonesia. 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.
21 dive centres on TecDiveTools teach TDI Advanced Nitrox in Indonesia: Jakarta (6), Bali (5), Gili Trawangan (5), Sulawesi (3), Alor (1) and Lombok (1). Each is listed above.
Walls drop past technical depths close to shore in Bali, Bunaken and Alor, which makes deep and decompression training efficient. Currents can be strong and change quickly, so choose an operator who plans dives around the tides.
Published prices for TDI Advanced Nitrox in Indonesia range across 3 centres in the TecDiveTools directory. That is IDR 7,500,000–9,000,000 (3 centres). 1 centre charges by the day instead, which is not comparable with a course total. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
Between 2 and 3 days, based on the durations 2 centres publish for it in Indonesia. The time depends on the centre's schedule, weather, and how quickly the required skills are demonstrated — agencies set a minimum number of dives, not a fixed number of days.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in Indonesia also teach RAID Decompression (3) and PADI TecRec Tec 40 (2). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
