Introduction

The Cave 2 course is the continuation of the pursuit to become a fully certified cave diver.  The course is designed to be the second step in educating and refining skills within the cave environment to protect the cave.  This is achieved through an intense diver education program that acquaints individuals with an understanding of established cave conservation procedures and an appreciation for the subtle dangers often associated with this overhead diving.  This course covers more advanced principles of cave diving, continuing with the skills and knowledge required to penetrate and navigate the underwater cave environment. 

Training includes an emphasis on awareness, cave dive planning, cave environments, stress management, navigation, T’s, Jumps, Gaps, conservation, standard procedures, emergency procedures, techniques, problem solving, and the hazards of cave diving.  Upon completion of the Cave 2 course, divers are fully-qualified cave divers, and their cave certifications do not expire.  They will be able to safely penetrate and navigate the cave, not only following and exploring the mainline but many of the side passageways and tunnels that make up this underwater labyrinth, while using no more than 1/3rd of their gas for penetration.

Cave training is not for everyone.  In fact, only very capable divers, who are quite comfortable in the water, should consider this form of diving.

Cave 1 and Cave 2 can be combined into a single 6-day program.

Course Information

The Cave 2 course is normally conducted over a 3 or 4 day period and involves a minimum of 24 hours of instruction (lecture and in-water) designed to instill divers with an appreciation for the dangers, challenges and beauty of the cave environment.  Special emphasis here will be placed on the unique challenges posed by overhead exposure and the identification, management and resolution of life-threatening adversity.

Course requirements include nine hours of academics and 8 dives at a minimum of 2 different locations.  One experience dive should be at a different cave site conditions permitting.

Equipment Requirements

Prior to the commencement of the course, students should consult with a UTD representative to verify equipment requirements.  All participants are responsible for providing all equipment or for making provisions to secure all necessary equipment before the start of the course.

In general, it is better for the student to learn while using their own equipment.  However, students should exercise caution before purchasing new equipment to avoid acquiring substandard or unnecessary equipment.  Please contact us prior to making any purchases.
