Which of the following tasks may a NAUI Divemaster perform?

A NAUI Divemaster plays a crucial role in supporting dive operations and assisting instructors. One of the key responsibilities of a Divemaster is to focus on record keeping and organizing divers. This task involves maintaining accurate logs of diver certifications, experience levels, and ensuring that dives are well-organized for safety and enjoyment. By effectively managing this information, the Divemaster helps promote a safe diving environment and assists in the overall administration of dive activities.

While conducting advanced technical diving lessons and teaching rescue diving techniques are important tasks, those are typically within the purview of certified instructors rather than Divemasters. Similarly, while Divemasters are skilled in emergency procedures and may provide assistance, the administration of first aid is best performed by individuals who have specific training and certifications for that level of care. Thus, keeping records and ensuring proper organization of divers is a fundamental and appropriate task for a NAUI Divemaster.
