Convert your SAC rate to a tank-independent RMV value.
Calculate RMVSurface Air Consumption (SAC) rate is the volume of air you consume per minute at surface pressure. It's a key metric for gas planning and understanding your diving efficiency.
Where:
• Perfect your buoyancy
Minimize unnecessary movements and finning
• Practice slow, deep breathing
Avoid rapid or shallow breathing patterns
• Streamline your gear
Reduce drag and maintain proper trim
• Stay relaxed and calm
Stress and anxiety increase air consumption
