Technical Wreck Diver in Thailand: 10 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 9 publish course prices.
TecDiveTools lists 10 dive centres teaching Technical Wreck Diver in Thailand. 9 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). 6 of these 10 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.

The centres listed above teach IANTD Technical Wreck 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.
10 dive centres on TecDiveTools teach IANTD Technical Wreck Diver in Thailand: Bangkok (3), Phuket (3), Krabi (2), Koh Phangan (1) and Pattaya (1). Each is listed above.
The Gulf of Thailand's technical wrecks are offshore expeditions rather than day trips: HTMS Pangan (65 m) and the Tattori Maru (75 m) are reached from Koh Tao, and HTMS Sarasin (43 m) off Pattaya and PAK 1 (43 m) off Koh Chang are closer. The USS Lagarto submarine (70 m) is a war grave: no penetration, and diving it is subject to US Navy permission.
Published prices for IANTD Technical Wreck Diver in Thailand range across 3 centres in the TecDiveTools directory. That is THB 45,000–49,000 (3 centres). 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 Thailand also teach TDI Advanced Wreck (11), RAID Advanced Wreck (3), ANDI Advanced Technical Wreck Level 2 (2), ANDI Advanced Technical Wreck Level 3 (2) and ANDI Advanced Technical Wreck Level 4 (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
