Extended Range in Sulawesi: 1 dive centre on TecDiveTools, with agencies, courses taught and a summary of what students say.
TecDiveTools lists 1 dive centre teaching Extended Range in Sulawesi, Indonesia.
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, 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.

About the course
Extended Range pushes staged decompression diving further than the base Decompression Procedures course, requiring dives past 33m/100ft with at least 2 dives deeper than 40m/130ft on a single decompression gas. It teaches more advanced gas planning, longer runtimes, and the added risk management that comes with deeper no-mistakes diving. It's aimed at divers who've already got Decompression Procedures under their belt and want to extend their working depth before moving into trimix. It sits between Decompression Procedures and Trimix Diver in TDI's technical progression — the natural next step once a diver is comfortable running shorter deco dives. It's open-circuit diving with doubles or sidemount and a dedicated decompression gas, and it opens the door to Advanced Trimix and deeper wreck/cave specialties.
The centres listed above teach TDI Extended Range in Sulawesi, 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.
