Enriched Air Nitrox Diver Scroll down for other classes
Want to extend your bottom time, lessen your surface interval, and maximize every dive? Become an Enriched Air Nitrox diver!
You will learn how to choose the proper blend of Nitrox for your dive profile, determine maximum depth limits for your Nitrox mixture, analyze your breathing mixture, and plan and safely execute each dive. Your instructor will teach you about the physiology of oxygen and nitrogen; advantages, disadvantages, and risks of nitrox; oxygen toxicity; hazards and precautions of handling oxygen; the concept of Equivalent Air Depth; use of EANx with standard Air Dive Tables; common gas mixing procedures; and more.
After your exam, you can qualify for the Nitrox recognition card, or go ahead and complete two dives to receive your Nitrox Diver certification card. And, your NAUI instructor can integrate your Nitrox course into your Scuba Diver course!
QUALIFICATIONS OF GRADUATES
Upon successful completion of this course, graduates are considered competent to utilize EANx in open water diving activities without direct supervision, provided the diving activities and the areas dived approximate those of training.

Underwater Ecologist
For years, divers have been becoming more environmentally aware of their surroundings, both as sight-seers and underwater photographers. There is a tremendous diversity of people interested in scuba diving and the ecology of two major oceanic environments, the Kelp Forests and the Coral Reefs. As we promote sound environmental diving techniques to help protect the planet's ecosystems, we must also learn how to better interface with the delicate kelp and coral environments. Through the NAUI Underwater Ecologist courses, you will learn more about our favorite diving environments.
Underwater Ecologist: Kelp Forest
The NAUI Underwater Ecologist: Kelp Forest specialty course focuses on the complex and productive ecosystem bordering much of the west coast of North America, from Alaska to Baja California. Kelp forests are also found in other cooler coastal waters of South America, Tasmania, South Africa, New Zealand, Australia, and many other locations. This course examines the kelp forests, their occupants such as mollusks, crustaceans, fish and marine mammals.
Underwater Ecologist: Coral Reef
Coral reefs are found in three major biogeographic regions of the world. The tropical western Atlantic (Caribbean), the Read Sea, and the Indo-Pacific region. Coral colonies are composed of thousands of tiny polyps, each with its own protective skeleton. The NAUI Underwater Ecologist: Coral Reef specialty course focuses on the vertebrates and invertebrates of the complex living reef. This course examines coral zonation, seagrass beds, lagoons, mangroves, and the common reef algae, invertebrates and reef fishes.
PREREQUISITES FOR ENTERING THE COURSE
- Age. Minimum is 15 years. (Junior certification for ages 10 - 14 years is allowed.)
- Certification: Scuba Diver certification or the equivalent is required. The instructor is to ensure adequate student knowledge and capability before any open water training and shall use skill or other evaluations to do so.
Training Assistant
This course is to qualify the diver in the skills and knowledge necessary to perform as a training assistant during diver training sessions. The key objective is to train divers to assist others during training activities overseen by an active-status NAUI Instructor. This course is to enhance the diver’s general skills and abilities and is not a substitute for specific NAUI courses which create NAUI leadership members. Although this course results in certification as a Training Assistant it does not confer any NAUI Leadership certification nor does it qualify the graduate to apply for or receive the benefits of NAUI membership. Consequently, this certification does not allow the graduate to be counted toward student instructor ratios.
QUALIFICATIONS OF GRADUATES
Certified training assistants are qualified to perform the tasks of:
- Temporarily directly supervise remaining students while an instructor conducts a skill with other students.
- Escorting no more than two diving students on the surface and on underwater tours.
- Assisting an active-status NAUI Instructor with other tasks which enhance the safety of students or improve the efficiency of diver training so long as the assistant is under the direction of the instructor and no other standards are violated.
PREREQUISITES FOR ENTERING THE COURSE
- Age: Minimum of 18 years.
- Certification: Training and experience equivalent to at least NAUI Advanced Diver.
- Rescue Certification: Certification in NAUI Scuba Rescue Diver or equivalent.
CPR & First Aid Certification: Current certification in First Aid and CPR. Note: Adult CPR training (approximately four hours) meets the requirement for Training Assistant certification. However, additional CPR training that includes two-person CPR and the use of rescue breathing barrier devices, e.g. pocket mask®, face shield, is required to meet the requirements for NAUI leadership certification.
SKILL REQUIREMENTS

Emergency management procedures as applied to divers in open water training in the applicable area. Deployment and use of emergency oxygen first aid. (Certification as an “oxygen provider” is recommended.) Review of first aid as related to diving in particular.
- Underwater communications techniques to be used by instructors and assistants. The deployment of dive area designators as appropriate for the area. Open water diving procedures and group control. The specifics of arranging and planning for a training dive. Techniques of escorting students on the surface and during underwater tours and during navigation exercises.

Dry Suit Diver
Dry suit diving has become increasingly popular in recent years. While dry suits were once used almost exclusively for situations such as ice diving or deep wreck diving, many sport divers are now using dry suits regularly for every day sport dives all over the world. Material technology, valve design, and zipper reliability have all improved to a point where dry suits deliver greater value per dollar for cold and temperate water diving. This course is to provide the diver with a basic understanding of the knowledge and skills needed to minimize risks and gain experience in dry suit diving. It will train scuba divers to properly use and maintain dry suits. By learning proper dry suit use and maintenance, you will extend your opportunities for diving to year-round.
