PADI or SSI Cavern Diver Specialty Course at Bonne Terre Mine
You can learn in two days, all you need to know to explore underwater caverns, in the most beautiful adventurous environment in the USA!

Cavern diving is defined as diving within the light zone of a cave, the area near the cave entrance where natural light is always visible. If you want to explore secrets hidden in caverns around the world, you'll need your PADI/SSI Cavern Diver certification

Cavern diving is spectacular and rewarding. It challenges our ability to plan and execute dives in a controlled and environmentally sensitive way. Caverns often hold the secrets of our past. We can sometimes find fossils and rock formations which have laid undisturbed for millions of years. The PADI/SSI Cavern Diver Specialty Course will enable you to develop your practical knowledge of the cavern environment and organize exploration in safety.

During your first open water dive you will practice line handling, use of reels, and emergency procedures in an open water environment. Your final three dives are conducted in the cavern environment. Your cavern penetration training dives limited to within the light zone and 130 feet total distance of the surface.
