Air consumption tips
Lowering your air consumption extends your bottom time and increases comfort. Small adjustments to your technique can lead to significant gas savings.

Monitor your gas supply
Never skip-breathe or hold your breath to save air; maintain a natural, continuous breathing pattern. Always turn the dive and surface according to the reserve pressure agreed in your briefing.
Buoyancy and trim
Good air consumption begins with proper buoyancy control and trim. When you are perfectly weighted and horizontal, you move through the water with minimal resistance, reducing physical effort.
Avoid using your hands to swim or stay upright. Every unnecessary movement increases your heart rate and oxygen demand, leading to faster gas consumption during the dive.
Efficient propulsion
Slow, deliberate fin kicks are far more efficient than rapid movements. Use the large muscles in your legs for long, steady strokes that propel you forward without causing fatigue.
Stop frequently to rest and enjoy the surroundings. Moving slowly reduces drag and helps you maintain a calm, rhythmic breathing cycle throughout the entire dive profile.
Relaxation and breathing
Mental relaxation is one of the most powerful tools for gas conservation. A calm mind leads to a lower heart rate and a more efficient respiratory exchange at depth.
Focus on long, deep exhales to ensure you are clearing carbon dioxide from your lungs. This reduces the urge to take the next breath, helping you settle into a comfortable and sustainable rhythm.
