Do you enjoy the idea of being able to dive more often without the fatigue? 

The SSI Enriched Air Diver course is SSI's most popular specialty course! This is easy to understand once you realise that diving with enriched air (nitrox) gives you more no-decompression time, especially on repetitive dives. Alternatively, you can use enriched air to increase your own safety margin if you breathe nitrox but plan your dives as if you were diving on air. If longer dives and being able to get back in the water sooner sound appealing, then this is the course for you!

During the course, you'll learn why diving with a gas which has a higher oxygen content, and lower nitrogen content, than air increased your bottom time along with specific considerations relating to the use of nitrox. You'll lean how to manage your oxygen exposure, set your dive computer to nitrox mode and how to analyse the contents of your scuba cylinder.

All required SSmaterials are included and for you to keep. The SSI certification fee is also included. You will need to supply your own scuba gear including a computer, or alternatively you can hire at a competitive rate. *Please note the cost of the nitrox fills and charter fees (unless indicated above) are NOT included in the course fee.


The SSI Enriched Air Diver course consists two main sessions:

  • Theory: - To be completed online prior to the course starting. 

  • There is a bit of reading that will need to be completed prior to starting so please make sure you come in to collect your manual. 

  • Diving: -  The SSI Enriched Air Diver course consists of two open water dives. The dive site itself is chosen based on conditions on the day, however your instructor will discuss options for this including trips to TaupoPoor Knights, Aldermans and Bay of Islands.

  • We're always going diving! We have heaps of shore dives, day trips, weekend adventures and more for you to get in the water! Every weekend throughout the season there are trips planned, so you're never short of options. Our social nights are a great way to make new dive buddies and new friends.

  • ​​As a Performance Diver student you get exclusive offers and pricing on a huge range of dive gear. If you're not ready to commit to buying your own then no worries - we have heaps of rental gear at a great rate for you. We want you to go diving, so we'll make it as accessible as we can!

Course Prerequisites:

  • Already be at least a certified SSI (Junior) Open Water Diver or equivalent.

  • Complete the Dive Medical form. Click here to print the SSI Medical Form for diving. If you answer YES to any of the medical questions you must complete a Dive Medical check with your Doctor and obtain written medical clearance before the start of the course as we can't allow you in the water without it.

  • Students must be at least 15 years of age. Parental consent is required for students aged 15 - 17 years of age. 

  • As well as basic dive equipment (which can be rentedyou are required to have a safety sausage, compass and knife. Please note, enriched fills and charter costs are not included as part of the course costings. 

  • You will have homework to compete before the course starts. The course is heaps of fun, but is also intense - we have a lot to learn in our sessions, and they run to a very strict timetable. Failure to complete your homework means that you are behind right from the start, and are holding your group back. This is, understandably, not fair on everyone else and is likely to result in you being removed from the course without refund! 
  • In order to receive the "February course special price" dives must be completed either off the boat or at the Bay of Islands. This is restricted to February dates only. Any changes to this schedule may incur a transfer fee and is up to the discretion of Performance Diver LTD.
