PADI Enriched Air Nitrox
Many divers assume nitrox lets them dive deeper. It doesn’t. What changes is the gas you breathe: air is about 21% oxygen and 79% nitrogen, while enriched air has extra oxygen added, typically 32% or 36%, leaving less room for nitrogen.
Less nitrogen means your body takes it up more slowly, so you can stay down longer before you reach your no-stop limit. With the right mix for the depth, that time is often almost doubled. It makes the most difference between 20 and 30 m, where divers on air usually run out of no-stop time long before they run low on gas.
Nitrox is also your first step towards tec diving.
