How can divers increase the accuracy of their surface air consumption (SAC) rate?

Determining the average surface air consumption (SAC) rate is essential for divers when planning future dives, as it helps in predicting how much air they will use at different depths and durations. To accurately establish this average, divers typically collect data over multiple dives, measuring their air consumption under various conditions. By calculating the average SAC rate, divers gain insights into their personal consumption patterns, which can help them in managing their air supply effectively and ensuring safe diving practices.

This method involves logging the amount of air used and the time spent at depth across several dives, which allows for a comprehensive understanding of individual air consumption behavior. Consequently, this accumulated data can be utilized for better planning and decision-making in future dives, enhancing overall dive safety and efficiency.
