How long does it take?

 

We rarely run the Cavern Diver course as a stand-alone course. It is part of larger scope of cave dive training. Divers usually earn the rating while pursuing the higher cave diving certifications.

 

Cave diving is a process: you attend training sessions and earn the ratings along the way. The pre-course academic and pool work will take some time, the actual cavern dives for PSAI Caver Diver certification will only take two to three days.

Where?

While the PSAI Advanced Buoyancy Control (ABC) is not technically required for Cavern Rating, your instructor is likely willing to accept you on a trip overseas only if he/she is confident that your dive skills are up to it. The ABC course, all required pool work and at least some of the Cavern Diver academics are done in Hong Kong (or China).

 

The actual cavern and cave dives require travel.

 

How much does it all cost?

We quote the courses as 'Tuition Only', you will then pay for the dives and travel as you go.

The Cavern Diver course is conducted in the “daylight zone” of any solid (rock) overhead. Cavern Diver course certifies divers to limited penetration in the daylight zone of overhead environments.

A diver that successfully completes PSAI Cavern Diver program will be qualified to:

 

  • Plan and conduct cavern dives in environments and conditions similar to their training, with the gases they are previously qualified to use to the maximum of 60 linear meters (depth plus penetration) from the surface
     

  • Determine the risks and hazards of a proposed cavern dive

 

Prerequisites

 

 

  • minimum of 25 logged dives

 

Course Structure

 

  • Approximately 6-8 classroom and practical demonstration hours

  • Minimum one confined water (pool) session

  • Land drills for line handling, guideline following with and without visibility

  • Four (4) open water dives
    - one (1) dive in the open area for purposes of practicing skills such as line following and touch contact without visibility
    - three (3) dives in the cavern zone.
