Tec Sidemount in Thailand: 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 Tec Sidemount 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 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
Learn the sidemount equipment configuration, an increasingly popular setup that offers superior trim, streamlining, and maneuverability for technical wreck and cave diving. This course teaches tank mounting at the sides of the body, gas-switching procedures with side-mounted regulators, and sidemount-specific buoyancy and trim techniques. Sidemount configuration reduces drag, improves horizontal positioning, and allows easier tank swaps—advantages particularly valuable in wreck penetration and tight cave passages. Tec Sidemount certification qualifies you for advanced technical wreck and cave exploration where streamlining and maneuverability are critical safety factors.
Assemble and configure sidemount tanks correctly; manage buoyancy and trim in sidemount configuration; execute gas-switching procedures at depth; navigate wreck and cave environments in sidemount gear; perform emergency procedures with side-mounted tanks
The centres listed above teach PADI TecRec Tec Sidemount 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.
2 dive centres on TecDiveTools teach PADI TecRec Tec Sidemount in Thailand: Koh Tao (1) and Phuket (1). Each is listed above.
Koh Tao's deeper pinnacles are close enough for routine decompression training, and warm water keeps long stops comfortable. Trimix depths mean going offshore: the Gulf's technical wrecks lie at 43–75 m.
Published prices for PADI TecRec Tec Sidemount in Thailand range across 2 centres in the TecDiveTools directory. That is THB 23,900–35,000 (2 centres). Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
5 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 IANTD Tek Sidemount Diver (11), TDI Advanced Sidemount (5), RAID Sidemount (2) and SSI XR Extended Range Sidemount (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
