Extended Decompression 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 Extended Decompression 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
A bridge to deeper technical diving without helium for sidemount and twinset divers in regions where trimix is unavailable. This course extends technical diving capabilities to 55 metres using compressed air as the primary breathing gas, with up to four stage cylinders containing custom nitrox blends for decompression. Students master complex multi-gas management, extended decompression obligations, nitrogen absorption and off-gassing, and deep air-based diving suitable for locations where trimix is impractical or cost-prohibitive.
The centres listed above teach RAID Extended Decompression 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.
2 dive centres on TecDiveTools teach RAID Extended Decompression in Indonesia: Bali (1) and Gili Trawangan (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.
One centre in the TecDiveTools directory publishes a whole-course price for RAID Extended Decompression in Indonesia: Gili Divers, at IDR 15,000,000. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in Indonesia also teach TDI Extended Range (12), IANTD Technical Diver (3) and PADI TecRec Tec 50 (2). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
