Tek Essentials Diver in Mexico: 10 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 5 publish course prices.
TecDiveTools lists 10 dive centres teaching Tek Essentials Diver in Mexico. 5 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). 4 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, 4 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.
