PADI Enriched Air Diver – Nitrox

Give your dives a boost of Nitrox

Explore the bottom of the sea for longer!
Diving with Nitrox means you are diving with less nitrogen and higher percentages of oxygen, allowing you to enjoy your dives for longer under the sea, exploring and visiting your favorite places.

Your deep dives (PADI – Deep Diver) will be more enjoyable than with ordinary air and that is why we recommend that you do both specializations.

In addition, diving with Nitrox will be more fun on your day of diving, as it allows shorter intervals between dives, meaning you'll dive more times in the same day..

It's no surprise that the PADI Enriched Air Diver specialization is PADI's most popular course.

How does the specialization work?

Much more than a specialization!

1°- Double learning

In order for you to receive the PADI Enriched Air Diver Nitrox certification, you only need to study the online teaching material and take an assessment to obtain the certification.

Exclusively at Água Viva Mergulho, in addition there will be a 1 in-person class and 2 dives at Ilha do Arvoredo.

The instructor will go over the most important points of the content in the in-person class, answering all your questions, and, in the next day, we will go for Ilha do Arvoredo to begin our adventures.

Have fun safely using Nitrox!

2°- Enjoy Ilha do Arvoredo with Nitrox

On the day of the dives, when you arrive at the school, you will put into practice the contents previously learned, together with the instructor who will be assisting you.

You will analyze the percentage of oxygen contained in the cylinder by using a specific instrument and will plan the dive, using tables or configuring the dive computer.

After all the preparation, just enjoy the natural beauty of Ilha do Arvoredo, enjoying the seabed for longer and following the stipulated safety limits.

Credenciado Água Viva
Your dives will be supercharged!

3°- More adventure with Nitrox on your back

With your certification in hand, you will be able to obtain Nitrox refills around the world, enjoying your dives for longer.

Whether you are practicing underwater photography, exploring shipwrecks or even on vacation in some paradisiacal place with little time for diving, the Nitrox will guarantee fun.

Additionally, the PADI Enriched Air Diver certification can be used as credit toward the PADI MSDT Instructor category.

Be a deep sea explorer with Nitrox!

Excellent experience
It has already started with the great welcome and guidance from Maicon. Super professional team, prepared for any incident; The materials they offer us are of good quality and in excellent condition. In my opinion, practicing in the pool was essential for safe diving and, above all, being able to count on the care and patience of instructor André made all the difference. And the experience ended perfectly, on the paradise island of Arvoredo. Congratulations Água Viva Mergulho/Florianópolis! Will I be back?❤️

It was a unique and wonderful experience. The boat trip was incredible, the crew was super helpful and friendly, the divers (Ryan, Fábio, Fiuza...) are super careful, fun and attentive... The diving baptism was sensational, the marine life in the place is incredible and very beautiful. I will definitely do it more often, it was wonderful.
Flávio Henrique
Great experience!
The experience was fantastic! If I were starting my career, it would definitely be my choice. The entire crew is to be congratulated for their commitment and dedication, but the photographer diver knows what he is doing very well! Don't forget to hire their services. PHOTOS ARE RECORDS FOR LIFE! There is no point trying to film or photograph with your own camera. It gets very bad. His camera and he are professionals. Worth every dollar! Congratulations to all of you! From the store staff, to the Captain. Congratulations on your professionalism, you know what you are doing!
Dener S
An incredible experience
I crossed 1/2 of Brazil to do this dive and it was worth every penny, super attentive crew, wonderful place, super peaceful dive. There was a moment when I felt seasick and the crew was super helpful, if you have the opportunity, choose the baptismal dive, it's a totally different experience, and MUCH BETTER, than just snorkeling. The location is perfect, the fish were everywhere, even on the stairs that lead to the boat, the divers (Ryan, Fabio, Davi, Fiiuza, I hope I haven't forgotten anyone's name) are VERY friendly, polite, happy and playful , I don't even know what else to write, it's an experience difficult to describe, just the boat trip to Ilha do Arvoredo is something unique. When the photos arrive I will update here.
Top diving
I am accredited, I had a great experience with the Água Viva group. I recommend Ilha do Arvoredo for diving.
Basic diving course
I took the open water diver course and had an excellent experience. The staff is very careful at all times and very competent, I loved it!
Wonderful, excellent staff
Scuba diving. The experience was wonderful, we went to the island of Arvoredo, even though the visibility wasn't the best (rough sea) we had the opportunity to see stingrays, turtles, seahorses, moray eels and dozens of fish and colorful corals, thanks in large part to the guide who he knows the place very well and gave us an unforgettable dive. I recommend.
Diego Morales
My official initiation into diving
I took the open water diver course, and I felt well educated. The practical classes cover much less content than the theoretical material, but by talking straight, the instructors provide training in different useful skills that you feel necessary.
Excellent organization and experience
Without a doubt one of the most organized operators I have ever dived with. Punctual, large and well-maintained boat. Experienced, attentive and friendly professionals provided a great experience.

About school

Ilha do Arvoredo


Escola Água Viva

In the essence of every diver there is a very strong desire to preserve nature. Curiosity about the world beneath the waves and the animals that inhabit the depths has attracted many generations of divers and we have inherited the tradition of protecting the environment that we enjoy every time we dive.

Diving is our passion and teaching new people about this world is our life goal.

Água Viva Mergulho was founded in 2012 on these pillars. We believe that every diver has a duty to preserve nature and we strive to incorporate this mission into our diving operations, whether collecting fishing hooks, plastic bottles or organizing specific seabed cleaning expeditions.

For all our dedication to training conscious divers and promoting environmental conservation actions, we were honored by the Green Star Awards.

Ilha do Arvoredo

The Ilha do Arvoredo Marine Biological Reserve is considered the best diving spot in southern Brazil, known for its marine diversity with various types of fish, turtles, seahorses and rays, as well as being on the migration route of humpback and Franca whales. The island is also an important archaeological site formed by burials characteristic of human occupation 4000 years ago.

The diving spots in Arvoredo differ in their characteristics, which can vary according to the formation of the bottom, minimum and maximum depths, most commonly found species, currents, or even specific characteristics, which provide a less conventional dive, such as a shipwreck, cave , etc.

The diving spots are all located in the southern portion of the island, the best known are: Ponta do Farol, Saco do Vidal, Saco do Farol, Baía do Engenho, Baía das Tartarugas, Saco do Batismo and Saco do Capim.
