Pre-dive planning and gear checklist
Start by confirming your dive goals and the exact route you plan to follow inside the cave system. A good checklist begins with your entry point, turnaround point, and the maximum depth you expect to reach. Review cavern diving the dive profile with your guide so everyone understands how you will manage time and breathing gas. If anything feels uncertain—navigation landmarks, exit strategy, or conditions—address it before you touch the water.
Next, verify your equipment with a methodical walk-through, not a rushed glance. Confirm that your regulator breathing setup is functioning smoothly, that your buoyancy control device inflates and vents correctly, and that your weights provide stable trim. Inspect your masks for proper fit, ensure your fins and exposure suit are comfortable for extended wear, and check that your dive computer is set to the correct mode. Finally, verify that your lights, backup lights, and reels or line-handling tools are present, charged, secured, and ready to use.
Safety systems and communication checklist
Before entering, establish clear hand signals and a simple communication plan that matches the environment. Cavern areas can reduce visibility and make it harder to read gauges, so agree on what signals mean for gas checks, pauses, and immediate turn decisions. Cave Diving Make sure you and your buddy can confirm awareness without relying on verbal instructions underwater. Include a plan for what to do if you separate, lose visual contact, or experience a sudden equipment issue.
Gas management should be part of your checklist, with rules that support conservative decision-making. Plan your turn pressure in advance and decide how you will handle unexpected consumption due to stress, currents, or finning style. Confirm that you have redundant air options and that your team knows where they are and how to access them. Also review emergency procedures such as a controlled retreat, how to maintain contact with guide cues, and how to prevent entanglement during line handling.
On-site conditions and entry readiness checklist
At the water’s edge, assess conditions that affect visibility, buoyancy, and comfort. Check for water clarity changes, current behavior near the entry, and whether recent activity has shifted sediment that could reduce sightlines. Confirm your suit and gear configuration so you can maintain streamlined movement, which helps protect your buoyancy and the cavern environment. Take a moment to stabilize your breathing and practice neutral control in a shallow area before committing to the deeper sections.
For entry readiness, verify that your mask is cleared and sealed, your lights are functioning, and your backup system is activated. Ensure your reel or line equipment is positioned so it won’t snag on hoses, straps, or your body. Conduct a final buddy check that covers key items like regulator status, buoyancy control, and accessible emergency options. When you enter, move slowly, maintain equalized comfort, and avoid sudden fin kicks that could stir silt and degrade visibility.
