The TDI Intro to Cave Course in Playa del Carmen will be your first incursion past the cavern zone. This course will teach you the necessary skills to safely dive in caves in backmount twinset or sidemount configuration while respecting the conservative rule of 1/6th towards gas management, and following only the main cave line.
This course does not prepare you to conduct cave dives involving complex navigation. For that, you must complete the TDI Full Cave Diver Course for which this course is a prerequisite.
This course will prepare you for hazards of cave diving such as loss of visibility, loss of guideline, team separation, loss of breathing gas and more.

Theory sessions,land drills, open water sessions and a minimum of 4-6 dives are required.
