PADI Cavern Diver

Can you see the light? If you dive within the light zone of a cave–the area near the cave entrance where natural light is always visible–you're in the cavern zone.

 

The Fun Part

The fun part is exploring secrets hidden in caverns around the world and having the knowledge and skills to do it correctly.

 

What You Learn

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 learn about

* 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
 

The Scuba Gear You Use

You use all the basic scuba gear plus some specialty gear for cavern diving. This is one of the few diving activities in which you won’t use your snorkel.
