TDI or IANTD Intro To Cave Diver Course

3 DAYS - 30000 THB

The Intro to Cave Diving course is an exhilarating yet demanding program designed for experienced divers who are ready to explore the captivating world of cave diving. This course serves as an introduction to the techniques, equipment, and mindset required for safe cave exploration, offering a blend of theory and practical skills to prepare divers for the unique challenges of diving in an overhead environment.

Unlike open water diving, cave diving presents a whole new set of challenges and risks. The Introductory Cave course begins by focusing on essential theoretical concepts, such as cave formations, gas management, communication, and emergency procedures. Understanding these fundamentals is crucial for maintaining safety and composure while navigating the intricate passages of an underwater cave system.


Our students can choose between TDI Intro To Cave or IANTD Introductory Cave course. This course we conduct in the Song Hong cave (Nakon Si province) and Sra Keow cave (Krabi province). If you are already certified Cavern Diver it would be a very good idea to combine this course with TDI Full Cave Diver training.
