The Cavern course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; in addition outlines specific hazards associated with cave diving. The cavern diver course in not intended to provide instruction for cave diving environments. The objective of this course is to train divers in the proper planning, procedures, techniques and hazards of cavern diving.
Knowledge and skills covered in this program include:
- Basic dive planning for overhead environments
- Basic cave diver propulsion techniques
- Basic guideline and reel use
- Basic cave diver communication
- Basic emergency skills
- Advanced buoyancy control and trim
Certification is through NSS-CDS, NAUI, TDI, IANTD, PADI.
The prerequisites are:
- Be at least 18 years old
- Have 25 or more dives
- Be certified to the Advanced Open Water Diver level or equivalent. Intro to Tech is recommended
- Possess Nitrox Diver certification
Students need above-average buoyancy control to enter the course. To determine if you meet this requirement is to stop swimming while diving. Upon doing so, one should instantly hover, motionless. The feet should not sink and the knees should remain in line with the shoulders. If you cannot accomplish this, then an Intro to Tech or remedial buoyancy training is recommended.
- The Cavern Diver course generally takes two days and approximately four dives. Depending on student progress, more time might be necessary, and this typically depends on ones prior experience in doubles, sidemount and/or any and prior technical training.
- With sufficient notice, we can usually accommodate requests for specific course dates.
