The journey of Cave Diving starts with the Deep Cavern/Sinkhole course. It is highly regarded by those who have completed it as the skill levels that are attained throughout the course can be used in all facets of diving for the life of the diver. This gives the successful candidate access to some of the most amazing sites found anywhere in diving such as: Piccaninnie ponds, Kilsbys Sinkhole, The Shaft and many more. The next level is Cave, this is the introductory level to overhead environment whereby the diver attains the skills to enter into cave systems that can have two divers side by side. Following on from Cave there is Advanced Cave which gives divers an introduction into trans-versing single file through underwater restrictions and more complex cave systems.
