Technical Diver in Krabi: 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 Technical Diver in Krabi, 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.

Candidates gain comprehensive knowledge of EANx operating limits and the application of enriched air and pure oxygen for optimized decompression procedures. This certification unlocks technical wreck, cave, and depth-extension training; it's the foundation for all open-circuit technical specializations.
Gas blending and mixture selection for depth and bottom time, decompression procedures and oxygen toxicity management, single and multi-gas-switch scenarios, emergency procedures at depth and during decompression, buoyancy and trim at technical depths
