Introduction

The Cave 3 course is a "technical cave" course.  This very demanding cave training seeks to refine the cave diving techniques of certified Cave 2 divers who have mastered the requirements of Technical 1.  To succeed, students must be experienced in the fundamental aspects of cave diving and comfortable in the use of stage bottles and a single deco gas for decompression.

Course Information

Training requirements include a minimum of 6 cave dives at a minimum of 3 different diving locations.  Special emphasis will be placed on the demands of extended overhead penetration; advanced navigation techniques including traverses, circuits and siphons); advanced gas management; restrictive passage negotiation procedures; precision propulsion techniques; decompression risk management and protocol; and extensive stage bottle management.

Cave 3 training is normally conducted over a 3 day period, and involves a minimum of 24 hours of instruction (lectures and in-water) designed to extend the diver’s overhead skills and appreciation for the dangers, challenges and beauty of the cave environment.  Upon completion of Cave 3 students may conduct a rebreather endorsement if already certified as a UTD mCCR/pSCR rebreather diver.

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.
