PADI Cavern Diver Specialty

Cavern Diver

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

This specialty can be used as one of five Specialty certifications required for your Master Scuba Diver certification.

What Is Involved?

During your first open water dive you'll practice line handling, reel use and emergency procedures without entering a cavern. But, for your next four dives, you're headed into the cavern, staying within the light zone and 40 metres/130 feet total distance of the surface. You learn:

  • Cavern navigation and line protocols
  • Planning, organization, techniques, problems and hazards of cavern diving
  • Special equipment use, such as lights, guidelines, reels and redundant breathing systems
  • Air sharing, disorientation, silting, line problems and other emergency procedures specific to cavern diving
  • Silt prevention, buoyancy control, air management and emergency procedures
  • Depth and distant limits for cavern diving
