What is a key advantage of using Nitrox for divers?

Using Nitrox, which is a mixture of nitrogen and oxygen with a higher percentage of oxygen compared to regular air, offers a significant advantage in terms of extended exposure times with minimal risk of decompression sickness. The increased oxygen content in Nitrox reduces the amount of nitrogen that divers take on during their dives. With less nitrogen in the system, divers can extend their bottom time, especially at certain depths, without significantly increasing their risk of experiencing decompression illness.

Additionally, this allows for longer dive durations and a greater safety margin when ascending, as the body can off-gas nitrogen more efficiently. This is particularly beneficial for repetitive dives and when diving at depths where traditional air might pose increased decompression risks.

While other options like warmth, lighter equipment, or faster ascent rates may relate to dive experiences or strategies, they do not provide the critical dive safety and efficiency advantages that utilizing Nitrox offers.
