Adv. Cave - Survey Diver in worldwide: 5 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 4 publish course prices.
TecDiveTools lists 5 dive centres teaching Adv. Cave - Survey Diver worldwide. 4 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). 3 of these 5 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, 3 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 training qualifies Technical Cave Divers to systematically map, photograph, and document cave passages using proper survey techniques and underwater photogrammetry. You'll learn line laying and baseline measurement, data recording under overhead conditions, and coordination with team members to ensure accurate spatial documentation. Survey diving opens opportunities to contribute to cave research projects, expeditions to unmapped systems, and scientific diving efforts that advance speleological knowledge.

Published prices for IANTD Adv. Cave - Survey Diver worldwide range across 2 centres in the TecDiveTools directory — roughly US$370 to US$850 at current exchange rates.

Between 2 and 3 days, based on the durations 3 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 NSS-CDS Cave Surveying (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
