Cavern: This is a challenging and very exciting course that includes four training dives over at least two days. During your first open water dive you'll practice line handling, reel use and emergency procedures without entering a cavern. But for your next three dives, you're  headed into the cavern, staying within the light zone and 40 meters/130 feet total distance from the surface. You will learn about:

  1. Cavern navigation and line protocols

  2. Planning, organization, techniques, problems and hazards of cavern diving

  3. Special equipment use, such as lights, guidelines, reels and redundant breathing systems

  4. Air sharing, disorientation, silting, line problems and other emergency procedures specific to cavern diving

  5. Silt prevention, buoyancy control, air management and emergency procedures

  6. Depth and distant limits for cavern diving

Cost: The line drills will be done in Miami and the dives will be on our annual camping trip to Ginnie Springs. cost varies but the minimum would be $220. You must be at least Advanced Open Water.
