< Enriched Air Diver (Nitrox) » Scuba Dive Courses Cape Town


You are diving on one of your favorite scuba dive sites and looking at your computer you realize that it is time to end your dive – your no decompression time is up! It is such a pity, because you are having the time of your life and besides, you still havr 100 bar left in your cylinder!

Extend your no decompression times by scuba diving with Enriched Air! Not only will you be able to stay under water deeper for longer, but you will also come out of the water feeling more energized and refreshed than you would if you had been diving on normal air.

Quick overview of the PADI Enriched Air Scuba Diver Course in Cape Town

  •  You must have your PADI Open Water scuba certification
  • Duration: 1 day
  • Minimum age to scuba dive: 15
  • The scuba dive course will take between 4 and 5 hours. It will focus on the special requirements of enriched air equipment, different air blends, using the PADI Enriched Air RDP (EAD), managing oxygen exposure, special applications of Enriched Air Diving and handling emergencies related to Enriched Air Diving.
  • Bring your swimsuit, sunscreen, towel and a snack.


The PADI Enriched Air Course is normally conducted in the afternoon or evening, here at the Into the Blue Scuba Dive Centre in Cape Town. Although we only do theory in this course, there is an optional scuba dive that can be done as well. This scuba dive is normally done on a different day than the theory. You will learn the following:


It consists of two theory parts:

  • Watching the PADI Enriched Air Diving Video
  • Reading the PADI Enriched Air Diving Manual and completing and reviewing the Knowledge reviews.


  • Oxygen analysis
  • Filling Enriched Air cylinders
  • Using EAD, Equivalent Air Depth formula
  • Oxygen partial pressure formula


  1. Why would I want to do the Enriched Air Diving Course?
    It extends your dive times by extending your no decompression limits, therefore allowing you to dive deeper for longer. This means that you can then enjoy your diving more as you will be able to explore more of your favourite dive sites without worrying that you will run out of air.

  2. Is it difficult?
    With the proper training that you get from this course, no it isn’t. You will be able to understand different enriched air blends, the proper filling and oxygen analysis techniques. Once you understand the theory behind it can be as easy as normal diving.

  3. Is using enriched air dangerous?
    No it isn’t dangerous, this is because of the extensive training that you receive in the course which teaches you about diving within safe limits. The course also highlights special emergency procedures for Enriched Air Diving so therefore you are always prepared for whatever may come your way.

  4. How long can I stay down for?
    Enriched air diving extends your no decompression limits so therefore it will extend your total bottom time. However how long your dive times are extended by varies from person to person depending on your air consumption rate and many other factors.

  5. What do EANx32 and EANx36 mean?
    EANx32 and EANx36 are the most common types of enriched air blends you get.  The number 32 and 36 are representative of the percentage of oxygen that is in the blend. Therefore in EANx32 you have 32% oxygen in the air blend compared to the regular 21% or normal air.

  6. Will you need to have decompression stops?
    No, with the PADI Enriched Air Diver course you are only extending your no decompression limits and therefore do not have to make decompression stops like Tec Divers.

“Top marks for safety and professionalism”....

The reason for giving five stars is not because my dive day was good - it was horrible, a complete washout, no viz, unpleasant swell, just all round yucky conditions.

However, that's nature, and dive operators can do nothing about it. What all dive operators should do is be as professional and customer-focused as the guys from ITB diving.

First thing to note is that ITB is considerably cheaper (by almost 1000.- Rand) than Simonstown operators, which is baffling considering that they also have the transport cost from Cape Town to budget for.

DMs, Instructors and Shopfloor staff are all super friendly and helpful; I even got picked up from my Cape Town digs and dropped off afterwards, free of charge.

On the boat, I saw all the emergency and redundancy gear I like to see: twin engines (VERY important!), Oxygen, comms gear, flares, the lot. Briefings were thorough, and buddy check was insisted on.

The trip to Seal Rock in the RIB was fun in the swell, but when we got there the captain did not let us dive because of the unsafe conditions. Disappointing as this was, he was totally right. Low tide and heavy swells are a dangerous combination this close to the rocks, and as for trying to get back into a RIB in seas like this....
We then tried the PMB wreck, where zero viz and nasty vertical swell separated the group and forced us out of the water after 25 minutes.

The captain did offer to try another spot but was honest enough to tell us that in his opinion it was going to be rubbish everywhere, and so we called it a day.

Back at the dive shop, we were all offered a re-schedule, but as I'm out of time I was given half my money back. I know from experience that this is not the norm in the industry, sadly.

Into the Blue is a top notch outfit that does things by the book, with a strong safety focus and very customer centered, on top of offering reasonable pricing and a fair refund policy. You'll have a hard time to find a better operator anywhere around. They'll definitely be my first choice when I pass through next, and for doing my IDC sometime this year.

Just hope mother nature will be in better mood then.
