Pre-Dive Checklist: Gear, Permits, and Readiness
Before you enter a cavern environment, confirm that your setup is purpose-built and your team is aligned. Start with a buoyancy plan and verify your exposure protection is appropriate for the water temperature. Inspect your mask seal, regulator flow, and backup air source. Bring a primary light and a redundant light with fresh batteries, then secure them so they won’t shift during cavern diving finning or line handling. Confirm you have a dive computer and a pressure gauge where you can read them without straining. Review your entry and exit points with your buddy, and agree on turnaround cues. Finally, ensure you’re diving with the right permissions and follow local guidance provided by your operator.
Safety Checklist: Lines, Visibility, and Team Communication
Cavern conditions demand calm teamwork and disciplined navigation. Confirm that a continuous guideline is present and clearly managed, and practice maintaining contact or proximity as your training requires. Check that your reel or spool is stowed correctly and that you understand hand signals for critical moments such as sharing air, stopping, or regrouping. Use a simple call-and-response plan for Cave Diving key decisions like turnaround and when to slow down. In low visibility, avoid sudden movements that can stir sediment. Maintain proper spacing so you don’t entangle hoses or interfere with line work. If anything feels off—equipment, buoyancy, or comfort—pause your plan and address it before crossing into more complex sections.
Experience Checklist: Skills, Comfort, and Navigation Goals
A smooth cavern dive depends on stable fundamentals. Verify you can hold neutral buoyancy without finning hard, and confirm your trim helps you move efficiently through narrow sections. Rehearse controlled starts and stops so you don’t drift off-course or overexert during kicks. Make navigation goals specific: know how far you’ll go, what landmarks you’ll reference, and how you’ll return using the guideline system. Plan your breathing pace to reduce stress and maintain consistent performance. Keep your breathing smooth, monitor your depth and time, and stay alert to changes in light and flow. If you’re exploring for the first time, focus on comfort and technique rather than distance.
