Overview
The desire for underwater adventure in caves, caverns and cenotes has settled in you?
Mexico has the most concentrated submerged cave system in the world. The Yucatan Peninsula is a gigantic karst plateau with the two longest underground systems in the world (Ox Bel Ha and Sac Actun). It is an ideal place to follow this course because the region offers cave dives of all types and levels with different passages and depths.
This course is an introduction to the basic principles of cave diving utilizing a single primary guideline. Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern diver course. The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.

Participants in the Intro to Cave Diver TDI course cannot fly in an airplane within 24 hours of their dive.
