If you're an avid scuba diver looking to extend your bottom time and reduce your nitrogen exposure, then the PADI Enriched Air Diver course is your next adventure. Commonly referred to as the Nitrox course, this specialty is one of the most popular PADI courses worldwide. In this blog post, we'll ‘dive’ into what the PADI Enriched Air Diver course entails, and the many benefits of diving with enriched air.
What is Enriched Air (Nitrox)?
Enriched Air, also known as Nitrox, is a breathing gas that contains a higher percentage of oxygen than regular air, which typically has about 21% oxygen and 79% nitrogen. Nitrox mixtures usually contain between 22% and 40% oxygen, with 32% and 36% being the most common blends.
By reducing the percentage of nitrogen in the gas mix, Nitrox allows divers to extend their no-decompression limits, reduce the risk of decompression sickness, and generally make their dives safer.
What You’ll Learn in the PADI Enriched Air Diver Course
The PADI Enriched Air Diver course is designed to teach you the fundamentals of diving with Nitrox. Here’s what you can expect to learn:
1. Advantages of Diving with Nitrox: Understand the benefits of enriched air, including longer bottom times and shorter surface intervals between dives.
2. Managing Oxygen Exposure: Learn about oxygen toxicity, how to manage your exposure to higher oxygen levels, and the importance of staying within safe limits.
3. Analysing Your Tank: You'll learn how to use an oxygen analyser to check the oxygen content in your tank, ensuring you know exactly what mix you're diving with.
4. Setting Your Dive Computer: Most modern dive computers are Nitrox-compatible. You'll learn how to set your computer for Nitrox diving and how to plan dives using enriched air.
5. Dive Planning: The course will teach you how to plan dives using enriched air, including adjusting your depth and time limits based on the gas mix.
The Benefits of Diving with Nitrox
1. Extended Bottom Time: One of the most significant benefits of diving with Nitrox is the ability to stay underwater for longer at certain depths. This is especially beneficial for repetitive dives, where nitrogen build-up can limit your dive time with regular air.
2. Shorter Surface Intervals: Because you’re absorbing less nitrogen, you can shorten your surface intervals between dives, allowing you to get back in the water sooner. This is ideal for dive trips where you want to maximize your time exploring underwater.
3. Reduced Nitrogen Absorption: Less nitrogen in your system means a reduced risk of decompression sickness (DCS), making your dives safer overall. While Nitrox doesn't eliminate the risk of DCS, it can significantly reduce it, particularly on multi-day dive trips or deep dives.
4. Less Fatigue: Many divers report feeling less tired after diving with Nitrox compared to air. While this is more anecdotal, it’s a benefit many Nitrox divers appreciate, especially on dive-intensive trips.
5. Greater Flexibility in Dive Planning: With Nitrox, you have more options when planning your dives, particularly on liveaboard trips or multi-dive days where maximising bottom time is key.
Why Take the PADI Enriched Air Diver Course?
The PADI Enriched Air Diver course is a straightforward and quick way to enhance your diving skills. It’s primarily a theoretical course, with no mandatory dives required, meaning you can complete it in a single day, at one of our training sessions. You can also combine it with other courses or dive trips to make the most of your time.
Once certified, you’ll have the flexibility to choose Nitrox whenever it’s available, opening up a new world of diving possibilities. Most dive operators offer Nitrox, and many liveaboards and dive resorts even provide it for free or at a nominal cost for certified divers.
The PADI Enriched Air Diver course is an excellent investment for any diver looking to increase their safety, extend their dive times, and reduce the risk of decompression sickness. Whether you’re a recreational diver who wants more time to explore, or you’re planning a dive trip with multiple dives per day, Nitrox can make your diving experience more enjoyable and less taxing on your body.
