IANTD – (Tecnical) Full Cave Diver TDI – Full Cave Diver

This Program is designed to train divers in safe cave diving and, if doing Technical Cave, the technical utilization of EANx for cave exploration, and the use of EANx and oxygen for decompression.


  1. If entering through modular route, must be qualified as Introductory Cave Diver, with proof of a minimum of 50 logged dives. If not qualified as Introductory Cave Diver must have proof of 100 dives or sufficient experience doing technical dives to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
  2. To enter Technical Cave (Technical Diver) in addition to #1, student must be qualified as an Advanced EANx Diver, or Advanced Recreational Trimix Diver or equivalent experience or training as determined by the Instructor.
  3. Must be a minimum of 18 years of age.
  4. Course Duration: 8 days (If the requirements of the standards are not met by the student, one or more additional days of training are required.)
  5. This Program must include a minimum of 500 minutes of in cave bottom time completed and there must be a minimum of 12 cave dives performed even if the time requirements are completed earlier (dive time for cavern or limited wreck or limited mine diver may not be credited).
  6. For students already qualified as Introductory Cave Diver or this Program must include a minimum of 400 minutes of cave bottom time within a minimum of 8 cave dives.
  7. IANTD Technical Diver must complete 350 minutes in cave bottom time and a minimum of 6 cave dives.


The full-cave zone is the highest and most demanding level of technical & cave diving. This includes everything which is not covered by the previous two levels, especially: any desired penetration distances, narrow passages, post-siphon dives, depths up to 40m EAD, any desired visibility up to 0m visibility, other gasses than air, use of stage bottles, long-distance dives, decompression dives and narrow passages down to the size of so-called “squeezes.” Equipment and training, which based on the nature of the dive, are much more rigid than for the cavern area. It is definitely a cave area, and is no place for a “normal” recreational diver to be without the right equipment AND the proper training.

To conduct an Introductory Cave Diver course, the following is to be included:

  1. The planning, organization procedures, techniques, problems, and hazards of cave diving
  2. Special equipment considerations including, but not limited to: lighting, guidelines, reel handling and redundant breathing systems
  3. Proper body position and buoyancy control, air-consumption management and emergency procedures

Information that describes the specific hazards of cave diving should include, but not be limited to: silting, line entanglement and breakage, disorientation from permanent lines and emergency situations unique to cave diving.



Auch im Jahr 2021 war eigentlich unsere Präsenz auf der BOOT in Düsseldorf geplant.

Doch leider wird 2021 nichts daraus da die Boot nun endgültig Abgesagt wurde.

Auf vielfache Anfrage haben wir, trotz allem, auch in diesem Jahr wieder einen Kalender von den Cenoten für euch zusammengestellt.

An dieser Stelle ganz besonderen Dank an Manuela, Martin und Pekka für das bereitstellen der wunderbaren Fotos.
