Adv. Cave - No Mount Diver in worldwide: 22 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 11 publish course prices.
TecDiveTools lists 22 dive centres teaching Adv. Cave - No Mount Diver worldwide. 11 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). 14 of these 22 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 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
This specialized cave technique teaches divers to navigate and exit cave systems using no mount configuration (bailout gas only or minimal tank arrangement), enabling passage through extremely tight restrictions where stage cylinders would create hazards. The course emphasizes refined gas management, stage abandonment protocols specific to no mount setup, and streamlined movement through narrow sumps and restrictions. You must first master sidemount configuration in the Advanced Cave - Sidemount course before progressing to this advanced specialization, which unlocks access to the tightest passages in technical cave systems.
22 dive centres on TecDiveTools teach IANTD Adv. Cave - No Mount Diver worldwide: Mexico (17), Thailand (3), Indonesia (1) and United States (1). Each is listed above.
At the same tier in TecDiveTools' cross-agency comparison, dive centres worldwide also teach TDI Advanced Cave Sidemount (6) and NSS-CDS Advanced Sidemount Diver (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
