UTD Cave 3 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 UTD 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.

  • Must meet UTD General Course Prerequisites as outlined in Section 1.6.
  • Must be a minimum age of 21 years of age.
  • UTD Cave Diver with a minimum of 25 non-training dives at the UTD Cave 2 level or above.
  • UTD Technical 1 or equivalent, with a minimum of 25 non-training technical decompression dives. Divers who were not previously trained by UTD must first secure the approval of the UTD instructor before entering this class and must be prepared to engage in supplemental training to remedy any training deficiencies. Additional time and fees are at the discretion of the instructor.
  • Must have proof of at least 200 logged non-training dives, with at least 60 non-training dives in double tank/cylinder configuration. 
  • Must be able to swim at least 400 yards/365 meters in less than 14 minutes without stopping.
  • Must be able to swim a distance of at least 60 feet/18 meters on a breath hold.

Course Limits

  • Student to Instructor ratio is not to exceed 3:1 during any overhead diving activity.
  • Gas consumption: maximum use of 1/3 of gas supply for cave penetration, variable based on team size, equipment redundancy and cave conditions.
  • No training dives are to exceed a depth of 160 feet / 48 meters.
  • Minimum 10 feet/3 meters of visibility to enter a cave.

Course Content

Training requirements include a minimum of six (6) cave dives at a minimum of three 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.

UTD 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 divers’ 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.
