This course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; in addition it outlines specific hazards associated with cave diving. The cavern course is not intended to provide instruction for cave diving environments.

Cavern diving is another type of diving that requires substantial training as it can sometimes prove to be hazardous, however, with the correct training, you can explore all sorts of overhead environments and catch a glimpse of some staligmites or staligtites.
