CAVERN DIVER
The PADI Cavern Diver Course

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

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 130 feet total distance of the surface.

You'll also cover the following:
• Planning, organization, techniques, problems and hazards of cavern diving
• Special equipment use, such as lights, guidelines, reels and redundant breathing systems
• Proper body position, buoyancy control, air management and emergency procedures
• Cavern diving hazards such as silting, line problems, disorientation and emergencies

This Specialty course certification also counts as one of five Specialty certifications required for Master Scuba Diver certification. Take the Master Scuba Diver Challenge!

Prerequisites:
• PADI Advanced Open Water Diver (or qualifying certification from another organization)
• Minimum age is 18 years old

Materials:
• TDI Diving in Overhead Environments Manual (included in cost of class)

Note: You will need to read the manual prior to attending class. Course fee does not include rental equipment.
