TecDiveTools lists 17 instructors teaching GUE Deep Primer worldwide.
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). 13 of these 17 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, 11 have a written synthesis of what reviewers say about them. How we read and count reviews.
