THE THIRD RULE OF SCUBA: ALWAYS MAINTAIN NEUTRAL BUOYANCY AT DEPTH A "safe" diver integrates proper diving practices at each and every phase of the dive. Preparation and proper execution directly impact the overall safety of the entire dive profile. To increase your safety while diving it is vital to follow the Third Rule of Scuba: "Always maintain neutral buoyancy at depth".

In addition to affecting the overall enjoyment of a dive, possible in-water "emergencies" will be better dealt with. Practically, when a diver fails to achieve neutral buoyancy, swimming becomes more difficult and tiring. Gas (air) consumption increases and fatigue is more likely. Swimming speed is decreased by a causal increase in drag making the dive "work" instead of fun. If a dive plan is improperly executed (or the plan was flawed/incorrectly planned) a diver finding themselves in a emergency situation will be better prepared to react if they are neutrally buoyant. Because the air in the BC will expand on ascent, only minimal effort is required to achieve positive lift. Further, by venting air from the BC during an ascent a diver or buddy team can perform a controlled emergency ascent. Remember, always plan your dives and dive your plan!
