Students are to demonstrate satisfactory open water
skills and perform in Divemaster roles for practice and evaluation during the
planning and conducting of the required open water dives. All such activities
are to be performed under the direct supervision of an active-status NAUI
instructor. 'The purpose is to evaluate the candidate in both knowledge and the
ability to apply it in the performance of practical work. The evaluated
activities also further the student Divemasters training in dive management.
- Rescue another diver in open water during a skin dive.
Perform scuba diving skills as listed below during an open water dive. The
staff is also to use this dive to demonstrate the organization and conduct of a
day dive for certified divers. Skills are to include:
Complete a night dive as a diver. During this dive the staff will
demonstrate the organization and conduct of a night dive for certified divers.
The dive is to be conducted in an area previously dived by the class during
- Pre-dive gear check for self and buddy.
- Entry, buoyancy check, swim to and front dive area, and exit.
- Distance swim - 880 yards (805 m) total during the dive.
- Descents, underwater swimming, and ascents.
- Weight belt removal and replacement on surface and bottom.
- Scuba unit removal and replacement on surface.
- Recover and bring to the surface from at least 6,1 m of water a ditched
weight belt of at least 4,5 kg.
- Make a simulated decompression stop at 4,6 m for five minutes
- Clear mask and regulator
- Retrieve regulator
- Buddy breathe on the bottom not using alternate breathing source.
- Perform a relaxed, controlled emergency swimming ascent from a minimum depth
of 4,6 m in open water.
- Maintain proper buoyancy using weights, breathing and BC.
Performing as a Divemaster using safety divers and assistants, control a
satisfactory rescue of a diver simulating an underwater accident in open water,
including organizing a search, transporting victim to shore or boat, victim care
and accessing emergency systems.
Prepare and present at least one pre-dive briefing for practice and one for
evaluation. The briefing is to be evaluated on depth of coverage as well as
safety and control measures. Evaluators are to remember the student is not an
instructor and may not possess polished instructional skills.
Performing as a Divemaster, assisting an Active-Status NAUI Instructor,
organize, and assist during an early open water experience for a class of
student divers. This may be accomplished by having the Divemaster class act as
entry level student divers and individually rotating through the Divemaster role
during a single dive.
Performing as a Divemaster, organize and conduct a beach dive for certified
divers. To be evaluated for the record. The student Divemasters should, if at
all possible, also organize and conduct their own evaluated boat dive with a
minimum of direction from the staff. If this is impossible, a new setting may be
Performing as a Divemaster, organize and conduct a dive for certified divers
in a significantly different setting from that of the previous dives, e.g. (boat
Organize and conduct a night or limited visibility dive for certified
divers. The student Divemasters are to organize and conduct their own night or
limited visibility dive with the staff evaluating. If night diving is not
possible, a simulation should be utilized.
The student Divemasters may run multiple dives on the same day up to a
maximum of three scuba dives and one skin dive. The greatest possible variety of
diving situations should be used. Open water dives should follow pre-dive
briefings as closely as possible. After each dive, the student Divemaster is to
conduct a debriefing. All diving activities are to be logged.
WHAT ARE YOU GOING TO LEARN ABOUT?
Students will be taught how to organize and conduct minimal risk open water dives as Divemaster. Practical, on-site demonstrations by the instructor or staff will be presented wherever possible.
Divemaster Duties - Techniques involved in planning, organizing and controlling a group dive. Included shall be: the analysis, selection and pre-dive evaluation of a dive site, pre-dive meetings and briefings, debriefing, Divemaster checklists and logs, use of safety divers, Divemaster responsibilities and dive flag use. Special procedures for working as a dive guide, leading trips and working with instructors on open water training dives are to be covered in detail.
- NAUI - Introduction to NAUI, NAUI programs, standards, statuses, NAUI products, services, NAUI procedures.
Divemaster Legal Responsibilities - Legal concepts such as negligence, standard of care, the necessity for liability insurance, waivers and indemnity agreements, taking of
artifacts and game, and the legal relationship between boat owner, Captain, instructor and divemaster. NAUI-specific information shall be included.
Shore Diving - Organizational problems of shore diving in salt and fresh water environments, including problems of entry and exit point selection, hazards, signals, flags, floats, surface support stations, current, tides, wind, sunburn, chilling, crowd control, small boat and other aquatic traffic.
Emergency Procedures - Actions to be taken if an emergency occurs, including effective use of assistants and equipment, underwater communications, diver recall methods, search techniques, assists and rescues, victim care Find handling, emergency and first aid equipment, accessing emergency systems, and accident reports.
Boat Diving - Techniques involved in small and large boat diving, including required boat equipment and licensing, navigation and rules of the road, boating etiquette and safety,
refueling, anchoring, docking, weather conditions and broadcasts, as well as charts, navigation aids and sources of information. The Captain/Divemaster relationship, diver management from a boat-based operation, ladders, platforms and safety lines, boat diving etiquette, equipment stowage, safety procedures and boat rescue techniques. Small boat diving (two to six divers) versus large boat diving operations are to be discussed.
Night and Limited Visibility Diving
- Procedures used and problems that can arise. Daytime reconnaissance of the night dive site is to be
emphasized, as well as planning and safety procedures, lights (underwater, surface, shore and boat), special equipment, typical and local hazards, buddy lines, rope signals, diver recalls, underwater communications, diving limits, lost diver problems, checklists, and problems associated with limited visibility diving both underwater and on the surface.

Deep and Decompression Diving - The problems a Divemaster must avoid or deal with in an emergency decompression situation. It is to be
emphasized that the need for decompression diving should be avoided in recreational diving. Included are the planning, concepts, methods and equipment used in such diving. The student Divemaster is to have a thorough knowledge of decompression and repetitive dive tables, dive computers and to know the first aid, treatment and transportation techniques for emergencies involving decompression sickness and suspected lung overpressure injuries. Altitude considerations and restrictions on flying after diving will be covered.
