Caver Diver Course

Advanced Nitrox/Deco Procedures This is the first step on the tech diver training ladder. Although technically separate courses (with considerable overlap between them), in North America they are almost always taken as a combined program, in so far as you really need both to participate in the kind of tech diving we do here.

The Cavern Diver course is the first in a succession of programs designed to lead to full Cave Diver certification. Although some students enroll in this course as a means of enhancing their recreational diving skills, the majority take this and the Advanced Nitrox/Deco Procedures program specifically to prepare for Cave Diver training.
Cavern diving is defined as the penetration of natural overhead environments while remaining within sight of daylight. Our course, however, goes well beyond this, covering the fundamental knowledge and skills required to prepare for Basic, Apprentice and full Cave Diver certifications.

Cave Diver
Students who successfully complete this course will have several options for continuing on to full Cave Diver status. Given our close proximity to one of the world’s most visited cave diving areas, its little wonder why this course is so popular with our more accomplished customers.

Who Can Learn

This course has the following prerequisites:

  • Be at least 18 years of age.
  • Possess a minimum of an Advanced Open Water Diver (or equivalent) certification. Enriched Air Nitrox strongly recommended.
  • Although there is no required number of dives to get into this course, successful candidates typically have several dozen or more logged dives and exceptional buoyancy control skills.

What is involved in learning to dive?

This course consists of self-study, classroom discussions, skill-development sessions in the pool, and four or more training dives. It takes four evenings and at least two (very) full days.

Where Do I Learn

We conduct the classroom and pool portions of the course here at Diver’s Den. Training dives take place at the nearby Florida springs.

When Can I Learn?

Cavern Diver courses take place bi-monthly. We spend Monday and Tuesday evenings in the classroom, Wednesday and Thursday evenings in the pool, and all day Saturday and Sunday at the springs. Scheduled on an as needed basis


The course fee is $395 and includes:

  • All instruction.
  • Self-study materials.
  • Certification card processing.
  • Students are responsible for supplying:
  • Personal diving equipment (see list below).
  • All air or gas fills.
  • Dive site admission fees.
  • Transportation to and from dive sites.
  • Accommodations and meals, as needed.

What Equipment Will You Need?

In theory, if you aspire to progress no further than the Cavern Diver level, you can take this course using little more than normal recreational equipment, plus a primary and backup light, and a personal safety reel or spool. Most students, however, take this course and the Advanced Nitrox/Deco Procedures program in preparation for Cave Diver training. In that case, you are best off using the same equipment you will need as a cave diver.
That includes:

  • Mask, fins.
  • Adequate exposure protection.
  • Dual cylinders with isolation manifold.
  • Technical diving harness and air cell.
  • Two high-performance regulators with DIN connectors, configured for cave diving.
  • Either two mission-capable dive computers, or one computer and a back-up depth gauge and timer.
  • Dive tables and slates.
  • One primary (canister) and two back-up lights.
  • Safety reel or spool.
  • Two cutting tools.

The preceding list is not intended to be used as a checklist for purchasing the least-adequate items that marginally fit the description of what is needed. Every single piece of cave diving gear must meet very stringent and specific requirements. Do not purchase any equipment without first consulting our staff.
