NSS-CDS
NSS-CDS Apprentice Cave Diver is Part I of the two-part process that leads to full NSS-CDS Cave Diver certification. The official NSS-CDS page explains that the Apprentice course focuses on developing practical cave-diving skills and knowledge while keeping the diver within strict limitations. It introduces cave procedures such as guideline use, gas planning, communication, propulsion, trim, buoyancy, emergency response, and the mindset needed to survive in an overhead environment.
This course is for divers who are ready to begin formal cave training, usually after cavern or technical-preparation work. The public NSS-CDS page frames Apprentice Cave as the first half of full cave certification, so prerequisites should be confirmed with the instructor and current standards before enrollment. Students should already have stable buoyancy, clean propulsion, strong situational awareness, appropriate equipment, and the humility to stay within Apprentice limits until completing further cave training.
Training normally includes academic development, land drills, confined or open-water skill work when needed, and cave dives focused on fundamental procedures. In High Springs, Florida, Apprentice Cave Diver is a serious step into the local cave-diving environment and should be treated as disciplined training, not a sightseeing pass. The expected outcome is a diver who can conduct limited cave dives within Apprentice restrictions and is prepared to continue toward full Cave Diver certification.
