Intro to Tech in worldwide: 188 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 57 publish course prices.
TecDiveTools lists 188 dive centres teaching Intro to Tech worldwide. 57 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). 131 of these 188 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, 108 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
TIER CORRECTION: Diver-tier introduction to technical diving equipment configurations and open-water diving skill enhancement. Teaches buoyancy, trim, situational awareness, and advanced gas planning techniques within a strictly no-decompression context. Designed as a bridge to Advanced Nitrox and Decompression Procedures, familiarizing divers with technical equipment (twin sets, sidemount) before committing to deeper technical courses. Can be combined with Advanced Nitrox at instructor discretion.
Divers must complete minimum 3 open water dives (max 4 if combined with Advanced Nitrox) to no deeper than 23m/75ft, demonstrating enhanced buoyancy control, proper trim, technical equipment assembly/configuration, and advanced gas planning skills. All dives must stay within no-decompression limits.

Published prices for TDI Intro to Tech worldwide range across 18 centres in the TecDiveTools directory — roughly US$280 to US$1,650 at current exchange rates. In each centre's own currency: €375–€500 (6 centres), $395–$1,650 (4 centres), IDR 5,050,000–7,500,000 (4 centres), THB 15,000–23,900 (3 centres) and ₱25,950 (1 centre). 4 centres charge by the day instead, which is not comparable with a course total. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
Between 2 and 5 days, based on the durations 17 centres publish for it worldwide. 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 worldwide also teach IANTD Tek Essentials Diver (23) and SSI XR Extended Range Foundations (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
