Cavern Diver students will be better equipped to assess whether they possess the skills needed for Cave Diver training. They can also better evaluate whether it is worth the time and expense to do so. Students must possess Advanced Open Water Diver and entry-level Nitrox Diver or equivalent certifications from a widely recognized diver training organization, or equivalent experience. This training may take place concurrently with the CDS Basics orientation or Apprentice Cave.
Students participating in any training program involving planned decompression must possess appropriate certification from a widely recognized diver training organization. This training must cover: Use of pure oxygen or oxygen-rich decompression mixtures and procedures for decompression diving. This training may take place concurrently with NSS-CDS Cave Diver training.
Additionally, instructors must screen and evaluate students to ensure they possess the necessary attitude, knowledge and skills before any further in-water training takes place. Instructors must refer students who cannot pass this screening process to opportunities where they can obtain remedial training. Only when students can pass the screening process may they continue their cavern/cave training.
