Tek Sidemount Diver in Thailand: 11 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 10 publish course prices.
TecDiveTools lists 11 dive centres teaching Tek Sidemount Diver in Thailand. 10 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). 7 of these 11 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, 7 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 sidemount configuration diving to depths matching the diver's previous certification level. Teaches advanced sidemount trim, redundant gas management on sidemount, equipment assembly and configuration, and specialized procedures. Ideal for technical wreck penetration and confined cave systems where sidemount excels.
The centres listed above teach IANTD Tek 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 days, based on the durations 1 centre publishes for it in Thailand. 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 Thailand also teach TDI Advanced Sidemount (5), RAID Sidemount (2), PADI TecRec Tec Sidemount (2) and SSI XR Extended Range Sidemount (1).
