The Benefits of Diving Nitrox vs Air

Is a nitrox certification “worth it”? 

If you fancy staying down longer and getting back in the water sooner, then yes; getting nitrox certified is worth it. You can take more photos, wave to more turtles, and spend more time exploring at depth.

Many divers wait too long to try nitrox. They don’t realise the benefits of an enriched air certification until they’re on holiday. Imagine this scenario:

There you are, on the second day of your diving adventure. Your first dive was deep, below 30 metres/100 feet. After a relaxing surface interval, you’re eager for dive two – a wreck.



If you plan to do a multi-day dive trip, a liveaboard, etc., do yourself a favor and get nitrox certified. Nitrox allows you to spend more time at depth compared to diving on air, which means you’ll get a lot more out of your diving holiday.

Even if you’re only making one dive, but it’s deeper than 15 metres/50 feet, nitrox is beneficial. Consider this:

  • If you plan a dive to 21 metres/70 feet on air, your maximum no-stop limit is 40 minutes.
  • If you’re diving 32 percent enriched air, the no-stop limit is 60 minutes
    (unless you use up the air in your tank before then).
