In diving, what is meant by 'return to assent point'?

The term 'return to ascent point' refers specifically to the action of returning to the surface safely after a dive. This encompasses the entire process of safely ascending from depth while considering factors such as safety stops and avoiding rapid ascents to prevent decompression sickness. A safe return to the surface is crucial in diving as it marks the completion of the dive and ensures that divers can safely exit the water without any adverse effects associated with diving.

Returning to the dive shop might be part of the post-dive process but does not encapsulate the immediate actions taken during the dive. Similarly, returning to the starting depth does not reflect the essential safety consideration of reaching the surface. Finally, while returning to the boat is an important part of a dive trip, it does not necessarily mean that divers have completed their ascent in a safe and controlled manner. The focus on safely reaching the surface highlights the importance of proper ascent protocols in diving.
