The Cavern Diver Specialty offers divers access into the veins of the planet Earth to explore the truly amazing and beautiful world of underwater caves. The Cavern Diver Specialty is the first of four steps toward the Full Cave Diver certification, and it allows the diver to explore the portion of a cave system within the daylight zone. Whether you decide to pursue additional cave training or not, the knowledge and experience gained in a Cavern course will greatly improve your open water dive skills and awareness.


PADI Cavern Diver

The Cavern course requires two (full) days, four dives for completion. Curriculum consists of class sessions, gear review and modification, surface guideline drills and underwater skills. Please be aware that enrollment in a course, at any level, does not assure certification. Due to the risks involved in diving an overhead environment, only those students who meet specific performance criteria will earn their certification.

Of key importance as the diver progresses from open water to the overhead environment is above-average buoyancy control and a high degree of comfort in the water. In-water skills include a no-mask swim along a guideline and air-share while under simulated zero visibility conditions.

Cavern Divers:

  • Experience the overhead environment in a controlled setting to determine if cave diving is of interest to you
  • Learn how to exit an overhead environment in zero visibility
  • Achieve improved buoyancy control
  • Master line handling skills appropriate for the environment

Equipment Considerations:

The Cavern Diver course serves as an extension of open water diving and your first introduction to the cave environment. Most open water dive gear can be adequately modified for this course. In addition to standard open water gear, additional required equipment includes two lights (one should be of a tubular body design - not pistol or lantern grip) and a safety reel for each diver in the overhead environment.

Travel Considerations:

This course cannot be taught locally in the DC Metro area. Please check the Travel page for upcoming trips to the Florida Springs.
