How long does it take?


Intro to Cave Diver course follows the Cavern Diver course and the cave dive are usually done on the same trip.

Before entering the course you must have successfully completed the PSAI Advanced Buoyancy Control and other pre-course work. the actual dives in Cavern Diver and Intro to Cave Diver courses can be completed in 4-5 days.


All overhead programs start with getting your skills - especially buoyancy control - up to the levels required from divers in overhead environments with the PSAI Advanced Buoyancy Control course. The ABC is done in Hong Kong (or sometimes in Guangzhou).

There are no caves suitable for diving in Hong Kong. All cave dives are conducted abroad. Cave diving trips for training you can join are arranged to caves in China, Philippines, Florida and Mexico several times a year.

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.

Intro to Cave Diver course is designed for divers who wish to make limited penetrations into the cave overhead environment where vertical access is not possible. This includes a variety of underwater cave zones found throughout the world in both fresh and salt water environments.
