What are two benefits of diving with nitrox?

Diving with nitrox, which is a mixture of nitrogen and oxygen with a higher percentage of oxygen than standard air, provides two notable benefits: longer dive times and shorter surface intervals.

The primary advantage of longer dive times comes from the reduced amount of nitrogen in nitrox compared to air. As divers breathe this gas mixture, they absorb less nitrogen, which directly translates to a lower risk of nitrogen narcosis and decompression sickness. Consequently, divers can remain underwater for extended periods before needing to ascend, allowing for more exploration and enjoyment of the dive site.

Shorter surface intervals result from the same principle. Since divers using nitrox absorb less nitrogen, they can complete multiple dives with reduced wait times on the surface before the next dive. This allows for a more efficient dive schedule, especially when diving in locations where time is limited or when divers wish to maximize the number of dives within a given period.

In summary, diving with nitrox enhances the diving experience by allowing for longer and safer dives, as well as minimizing the time spent at the surface between dives.
