The Rescue Diver course is the third level qualification in the American international system, following the Advanced Open Water Diver qualification (AOWD). The course usually covers most of the following topics:
Self-rescue and diver stress
Emergency management and equipment
Panicked diver response
In-water rescue breathing protocols
Dive accident scenarios
In many training agencies, these dives represent introductory knowledge and skills that may be further refined in a speciality course.
