How does nitrox diving work?

Why do you dive with nitrox?

The benefit of using nitrox instead of regular gas is that it helps increase your allowed diving time as it offers less nitrogen (and more oxygen) for you to inhale, thus reducing the amount of nitrogen that will quickly dissolve into your body—thereby lengthening your no-decompression limit.

Can anyone dive with nitrox?

Not Suitable for Deep Diving

Before you can use nitrox in scuba diving, you’ll need to go through special training and learn certain procedures in handling this gas. One misconception divers have about these key elements is that they will help in deep diving.

Is it better to dive with nitrox?

Nitrox proves to be especially useful for divers, who want to perform more than one dive per day. Due to having absorbed less nitrogen on the first dive, Nitrox divers will have a longer allowable bottom time on a repetitive dive.

How deep can you dive on nitrox?

However, when diving on nitrox, the potential for oxygen toxicity lurks well within the depth range of recreational diving: the maximum depth on 32 percent nitrox is 121 feet; on 36 percent nitrox, it’s just over 100 feet. Many divers regularly cruise at these depths and even deeper without giving it a second thought.

Can you stay down longer with nitrox?

Many people think that nitrox allows you to dive deeper and stay down longer, but this is simply not true. Nitrox is a shallow-diving gas. While it can extend no-decompression limits (NDLs) compared with air, you still breathe at the same rate, so you’ll still breathe the tank down at the same rate.

How do I get certified to dive with nitrox?

It’s possible to earn your nitrox certification in just one day. Simply complete the online course and schedule a short practical session with your instructor. The two dives are optional. You can also earn a nitrox certification simultaneously with another course.

Is it worth getting nitrox certified?

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.

Does Nitrox improve air consumption?

Misconception #1) Your air consumption will improve if you dive with nitrox. … However, a higher percentage of O2 allows you to stay at a safe depth longer than someone diving on air before having to proceed to a shallower depth due to no decompression times.

What does the presence of a Nitrox tank wrap signify?

Because oxygen-rich gas mixtures cause greater heat loss than air does, you may need additional thermal protection for Nitrox diving. … The pressure of a Nitrox tank wrap signifies a cylinder that has been pre-filled with EAN32.

At what depth do you need to decompress?

The deeper and longer your dive the more chance you need decompression stops. Shallow dives of 6-10 metres (20-30 feet) you can spend over 200 minutes without a decompression stop. Dives to over 30 metres (100 feet) limit your dive time to around 20 minutes before a decompression stop is required.

Do you need a special regulator for Nitrox?

It is not essential to buy a special regulator if you only plan to dive with mixtures containing 40 percent oxygen or less. The real value of a dedicated Nitrox regulator is shown in situations where levels of oxygen higher than 40 percent will be used. …
