Adv. Cave - Sidemount Diver in Thailand: 3 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 2 publish course prices.
TecDiveTools lists 3 dive centres teaching Adv. Cave - Sidemount Diver in Thailand. 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 3 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 specialized cave course teaches divers already qualified as Technical Cave Divers to master sidemount cylinder configuration within cave systems, where streamlined tank placement improves profile and navigability through tight passages. The focus is on sidemount-specific trim and buoyancy control, gas management across multiple independent sidemount cylinders, and stage abandonment from the sidemount position. Sidemount cave diving unlocks exploration of restricted passages and technical sumps that would be hazardous with back-mounted tanks, and is a prerequisite for the Advanced Cave - No Mount specialization.
The centres listed above teach IANTD Adv. Cave - Sidemount Diver in Thailand. 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.
3 dive centres on TecDiveTools teach IANTD Adv. Cave - Sidemount Diver in Thailand: Bangkok (1), Koh Phangan (1) and Phuket (1). Each is listed above.
Thailand's caves are a step up from showcase training systems: Khao Sok's limestone caves and the deep sinkholes of Sra Keow near Krabi and Song Hong in Trang combine depth with overhead, and see far fewer divers than the Yucatán. They suit divers who want to build cave skills in more challenging conditions — and Phuket, Krabi and Khao Sok keep a cave course within reach of a beach holiday.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in Thailand also teach TDI Cave Sidemount (3). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
