This is the last step to get certified as a TDI Full Cave Diver. At this level, advanced cave diving planning for complex navigation and execution of different types of cave diving scenarios are introduced. This course expands the previously learnt skills and emphasizes in dive planning and skill perfection through actual cave diving penetration.
During this course the students learn about properly marking their exit lines as they encounter multiple points of navigation and learn to safely plan dives to complete simple and complex circuits and traverses.
The duration of this course when taken on its own and the student is already certified as Intro to Cave diver is a minimum of 5 days. The skills learnt in the Cavern and Intro to Cave course are reviewed before going into the complex navigation portion of the course.
When the course is taken in one shot starting with Cavern all the way to Full Cave, it can be accomplished in a minimum of 8 days.
The Side mount Diver course is recommended before starting with cave diving training and it adds 2 days at the beginning of the full cave course.
