The Advanced Open Water Diver Course makes you a more confident, experienced and safer diver which means that every dive you do becomes more fun (you are more relaxed so you notice more, your air lasts longer, etc). For example mapping a Wreck on the Wreck Adventure Dive, buoyancy tasks during PPB and so on. You will get specific tasks under water for certain forms of diving. You already have the basic knowledge and what we do is expand upon this knowledge and apply it to specific forms of diving in the Open Water environment.

There is not as much theory involved as in the Open Water Diver Course and there is no final exam. Upon completion of this course you will have a recommended depth limit of 30m and an absolute maximum of 40m (the same depth limit as an instructor). The other 3 dives are elective dives and you can choose from a range of adventure dives such as: Wreck, Multilevel, Drift, Fish ID / A.W.A.R.E, Search & Recovery, Boat, Peak Performance Buoyancy (PPB), U/W Naturalist, Night, etc. Two of the dives are Deep and Navigation, - these are known as core dives. The most commonly cited advantage by Nitrox users is that they feel less fatigued and suffer from fewer headaches over repetitive dives on multi-day dive trips.Each dive of the Advanced course is called an Adventure Dive and after completing 5 Adventure Dives you will become an Advanced Open Water Diver.

In fact, many recreational divers choose an air computer with Nitrox to profit from the considerable extra safety margin that the gas provides as well as the significant benefits in energy and alertness. However, it is not necessary to own or rent a Nitrox computer to use Nitrox successfully or safely. NAI'A has Nitrox diving computers available for rental use. Many people like to dive Nitrox using a programmable-mix Nitrox computer to achieve the maximum bottom-time benefits that the gas allows at depths shallower than 130 feet. If you would like to take the PADI Nitrox Diver course aboard NAI'A, please request this upon booking so that we can confirm the availability of the instruction during your chosen cruise date. The course involves approximately four hours of lectures culminating in an exam and you then have the option of using Nitrox immediately. The PADI course is succinct, interesting, simply presented and designed with traveling live-aboard divers in mind. You can become certified as a PADI Nitrox Diver during your NAI'A cruise. The NAI'A system and its operators are also capable of providing specific mixes between 21%-100% by special request for recreational or rebreather diving. We use a sophisticated high-capacity membrane system to achieve the standard 32% (NNI) mix. NAI'A offers Enriched Air Nitrox (EAN) to divers who are certified to use Nitrox by any reputable training agency.
