So why do SO MANY divers become Nitrox Certified?
The Enriched Air (Nitrox) Diver Specialty course is PADI's most popular Specialty course — and for good reason.
Nitrox, also known as Enriched Air (EANx), contains less nitrogen than regular air. For divers, this mix offers benefits that allow you to get more from every dive.
Here are seven reasons you may want to consider taking the Enriched Air (Nitrox) Diver Specialty course:
1) More Time Underwater - Enjoy more time exploring reefs and wrecks, especially deep dive sites, thanks to longer no-stop limits when diving on Nitrox.
2) Shorter Surface Intervals - Nitrox allows you to make the most of your limited time by spending less of it waiting between dives.
3) It’s Ideal for Liveaboards and Multi-Dive Days - Nitrox leaves your body faster, which is better for diving multiple times a day and multiple days in a row.
4) Get Certified in Just a Few Hours - Most of the course can be completed online from home, followed by a short in-person session.
5) Unlock More Dive Opportunities - Some dive centers require an Enriched Air (Nitrox) certification for deeper dive sites or specialized dive profiles.
6) PADI Advanced Open Water Possibilities - Once you earn the Enriched Air (Nitrox) Diver Specialty course rating, this can also be used to earn the PADI Advanced Open Water rating.
7) PADI Master Scuba Diver Possibilities - Once you earn the Enriched Air (Nitrox) Diver Specialty course rating, this can also be used to earn the PADI Master Scuba Diver rating.
As you can ascertain, there is a reason (or seven of them), why earning the Nitrox rating is the most common certification other than Open Water! There are a lot of extraneous perks from just one certification.
