The type of cave dives students make at each point during their training is structured so that learning takes part at an even and progressive rate. For example, during the Cave Diver- Level I curriculum , students make a series of relatively conservative cave dives. Successive dives may be into cave systems that are more challenging than those preceding them. II course , students may begin making planned decompression dives. They also begin exploring offshoot tunnels that radiate from the main passage.
Students also begin more extensive cave exploration.
They may make traverses from one cave entrance to another, or complete a circuit of a cave system with complex, interconnecting passageways. Students at this level also receive an introduction to basic cave surveying techniques. Emergency training at each level also proceeds at a progressive rate. As the training progresses, this practice extends into the cave environment. Some of this practice includes emergency drills simulating loss of breathing gas supply, loss of light and a possible break in the continuous guideline.
