What is the concept of "The Rule of Thirds" in diving?

The concept of "The Rule of Thirds" in diving primarily pertains to the management of air supply and emphasizes safety during dives. According to this principle, a diver divides their total air supply into three segments. One third of the air is allocated for the descent and exploration of the dive site, another third remains reserved for the ascent and safety stops, and the final third is saved as a contingency reserve.

This method ensures that a diver does not deplete their air too quickly and allows for a safe return to the surface, accounting for unforeseen delays or emergencies. By reserving a portion of the air supply specifically for ascent and safety stops, divers can significantly reduce the risk of complications such as running out of air before safely surfacing.

This concept is crucial for promoting a safety-first mindset in diving practices, helping divers manage their resources effectively during underwater adventures.
