Phase 1: Knowledge & Planning
Students begin with eLearning or a classroom review of cave diving policy, gas matching, psychological aspects, communication, gear setup, and problem-solving strategies.
Phase 2: Skill Training in Real Caves
Across 8 dives at 3 different cave sites, students practice guideline handling, stress management, propulsion techniques, and backup navigation. Exercises include jump/gap reels, lost line and lost diver drills, air-sharing, and light failures—all under instructor supervision.

Students receive personal feedback and progress at their own pace. Each dive builds on the last, refining control, confidence, and awareness.
