TDI intro to cave diver course


The TDI Intro to Cave Diver course is designed for certified divers seeking to expand their underwater adventures into the challenging and fascinating realm of cave diving. This course builds on skills learned in the Cavern Diver course, focusing on more complex cave environments and advanced diving techniques.

                                     Course Structure

The TDI Intro to Cave Diver course includes both theoretical and practical components. Classroom sessions cover:

  1. Cave Diving Principles: An in-depth look at cave environments, potential hazards, and the differences between cavern and cave diving.
  2. Dive Planning and Navigation: Advanced dive planning, including gas management, penetration limits, and the use of permanent and temporary guidelines.
  3. Equipment Configuration: Detailed instruction on the specialized equipment required for cave diving, including sidemount configurations, dual tanks, and backup systems.
  4. Emergency Procedures: Training on handling complex emergencies such as entanglement, lost line scenarios, and out-of-air situations.

                                    Practical Training

Practical training involves a series of dives in actual cave environments under the supervision of a certified TDI Cave Diving Instructor. Key skills practiced during these dives include:

  1. Line Handling and Management: Proper use and placement of guidelines and markers for effective navigation and safe exits.
  2. Buoyancy and Trim Control: Maintaining perfect buoyancy and horizontal trim to avoid disturbing the cave environment and maintain visibility.
  3. Team Communication and Coordination: Effective use of hand signals, light signals, and touch contact to communicate with dive buddies in low visibility or zero visibility conditions.
  4. Problem Solving and Emergency Management: Realistic scenarios to develop and refine problem-solving skills and emergency response procedures.


To enroll in the TDI Intro to Cave Diver course, divers must be at least 18 years old and have completed the TDI Cavern Diver course or equivalent. They should also have a minimum of 50 logged dives.


Upon successful completion of the course, divers earn the TDI Intro to Cave Diver certification, allowing them to explore cave environments beyond the light zone while adhering to the training and safety protocols.

The TDI Intro to Cave Diver course is an essential step for divers aiming to safely navigate and explore the complex and captivating world of underwater caves.
