Dive Deep and Ace the SDI Computer Nitrox Test 2025 – Breathe Easy and Conquer the Seas!

Using Nitrox for diving primarily offers longer bottom times and shorter surface intervals due to its reduced nitrogen content compared to air. When divers breathe Nitrox, which typically has a higher percentage of oxygen, the amount of nitrogen they inhale is decreased. This results in less nitrogen absorption into the body during the dive, which lowers the risk of nitrogen narcosis and decompression sickness. As a result, divers can spend more time at depth without exceeding safe nitrogen limits, leading to extended bottom times.

Moreover, because less nitrogen is absorbed, divers may also be able to shorten their surface intervals. This is particularly advantageous for those looking to maximize their dive time on multilevel dives or multiple dives in a day. In comparison, the other options provided do not accurately reflect the primary benefits of using Nitrox, as they focus on features that are not relevant to Nitrox diving, such as depth limits, cost, air pressure, or visibility.
