One of the most beautiful and exciting places to dive in the underwater world is the "cavern".  Come with Michael O'Leary into the most exciting caverns every imaginable. 

Cavern diving  is the exploration of an overhead environment while remaining within the portion of the light zone, which is illuminated by sunlight.  It differs from cave diving in that, while cave divers may penetrate thousands of feet/meters, cavern divers go no further than a linear distance of 200 feet from the surface.  The maximum depth for diving in a cavern is 100 feet.

The course is designed to train the open water diver to dive safely in an overhead environment.  This course is an extension of recreational diving designed for the use of a SINGLE TANK, and upon completing the course, a diver will possess the skills,  knowledge, dive planning abilities, and  problem solving techniques to safely cavern dive within no-decompression limits.

Upon completion of this course you are eligible for the Intro-To-Cave Course, or try our 3-Day Combo course which encompasses Cavern and Intro-to-Cave.

• Prerequisite:  Open water Certification is required .
• Certification by NACD/ NSS-CDS/TDI

Fee: $300.00 each two or more students; $450.00 for private class plus certification fee; add Nitrox course for an additional $150.00.  Course fees are paid directly to the instructor, in cash, at the beginning of each course.

Registration:  To register for this course, a deposit of $100.00 is required.  Early registration is important because classes generally run full!  Enrollment in an NSS-CDS or NACD,  or TDI 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.  As the diver progresses from open water to the overhead environment, of key importance is above-average buoyancy control, awareness,  and a high degree of comfort in the water.  Water skills will include a no-mask swim along a guideline and air-sharing while under simulated zero visibility conditions.

Register early and get the dates your requested...  Don't be caught with your pants down...
