I always start with a solid plan—map the route, mark the reef edges, and set a clear exit before I even hit the water. That keeps me focused and avoids wandering, so I’m not using more air or energy than needed. I keep my gear light but reliable, and I double‑check my dive computer and backup regulators so I never have to make a hasty surface call because of a glitch. For waste, I stick to the 5–2–1 rule: five minutes to surface, two minutes to a safe exit, one minute to double‑check equipment. I also avoid touching corals or nudging the sand, and I keep my ascent slow to reduce bubble risk. That way I protect the reef, stay safe, and keep my dive time efficient.
