TDI Advanced Cave Sidemount Diver Course

The TDI Advanced Cave Sidemount Diver course’s objective is to teach how to safely dive into cave passages so restricted that it becomes necessary to remove equipment to pass. It focuses on the stress management and mind preparation as well as on equipment removal and advanced propulsion techniques.

The TDI Advanced Cave Sidemount course is designed for experienced side-mount cave divers who wish to push their skills and knowledge to the limit. Students will learn how to safely remove equipment in order to pass restricted areas and how to solve equipment problem and failures directly underwater.

A proper mental preparation and the capacity of calm, sound judgement in stressful situations is paramount as the hazards increase in confined passage.

At that level, cave passages become so small that in some cases divers must solve problems without the assistance of the team mates, in zero visibility and in very small caves, which leads to diver’s autonomy in all situations.

The TDI Advanced Cave Sidemount course is an extreme cave diving course and is a real challenge for the student.

A word of warning

This is an extreme type of cave diving and it is certainly not meant for everybody. 

Students must be conscious that by engaging in such an advanced type of diving, they expose themselves to specific hazards and dangers beyond of what is usually accepted by the vast majority of the cave diving community.

Also, participants must be conscious that in many situations, there is no possibility for the instructor or/and dive buddy to help in case a real problem arises. This means that divers must be completely self-reliant.
