You will learn the techniques during the land drills and reinforce them during freshwater dives in the cenotes. At least four separate cavern dives are made in at least two completely different cave systems.
Afterwards, a written exam must be taken. If you need additional training sessions, this will be discussed directly. It may be necessary to take a break for independent work on skills and knowledge before continuing with the course.
The course deals with body positioning (trim), buoyancy, emergency procedures, how to follow the guideline, the use of different types of reels and the different propulsion techniques. Additional course topics are anti-silting techniques, line entanglements, loss of orientation and adaptation of equipment for this type of environment.
