What you will learn
– Core cave-diving control: You will work on buoyancy, trim, propulsion, awareness, positioning, and team control inside the cave environment.
– Guideline and line procedures: You will practice awareness of guidelines, reels, spools, jumps, gaps, markers, and line protocols appropriate to each level of training.
– Gas management and planning: Disciplined gas management, team awareness, turn pressures, contingency planning, and decision-making.
– Communication and team procedures: Light communication, hand signals, touch-contact communication, team positioning, pre-dive checks, and procedures.
– Emergency response and problem-solving: Realistic procedures for common cave-diving problems, including reduced visibility, lost line, lost diver, light failures, gas-sharing, and team-based exits.
– Full cave navigation: Advanced navigation, including cave dive planning, route awareness, jumps, gaps, circuits, traverses.
This program has a minimum duration of 8 days, but the training adapts to your pace. If you need more time to consolidate skills, build confidence, or consistently reach the required level, we can extend the process.
Your progression will depend on your performance, control, comfort, and decision-making throughout the course. Our goal is not only to complete the minimum required days, but also to help you develop the skills, safe habits, and discipline needed to dive in caves with greater confidence and safety.
