Cavern Diving

Cavern Diving is SSI’s premier entry-level natural overhead-environment program. Designed to take your diving beyond open water, it develops disciplined line handling, conservative gas management, precise buoyancy control, and effective team communication. Remaining strictly within the daylight zone and utilizing simple single-line navigation with the rule of sixths, you will learn to evaluate cavern sites, deploy continuous guidelines, and manage emergencies. Through a combination of digital learning and practical, performance-based training, you’ll gain the confidence and competence needed for safe overhead exploration.

SSI Full Cave Diving teaches you complex underwater navigation skills as you learn how to manage a traverse, jump, tee, and gap within a cave system. Performing advanced cave dives is as technical as it gets and will take you to exciting dive locations worldwide. Prepare to dive the deepest caves in the world by learning lost line, lost light, gas sharing, and lost diver procedures. Utilizing either an XR Sidemount, Twinset, or Rebreather Total Diving System, the Full Cave Diving program is SSI’s highest-level overhead environment certification, providing all the tools you need to explore the world’s underwater caves.
