  3. Plan Your Dive: Thoroughly plan your dive, including entry and exit points, gas management, and navigation. Stick to your plan and avoid exceeding your limits.
  4. Dive with a Buddy: Always dive with a buddy who is equally trained and experienced in cave diving. Maintain close communication and visual contact throughout the dive.
  5. Follow Guidelines and Rules: Use guidelines (a reel and line) to mark your path and ensure you can find your way back. Never stray from the guideline.
  6. Monitor Your Air Supply: Keep a close eye on your air consumption and ensure you have enough air to return to the surface safely. Follow the “Rule of Thirds” for air management: one-third for the way in, one-third for the way out, and one-third as a reserve.
