The Rescue Diver course is a scuba diving course designed to teach divers how to prevent, recognize, and respond to diving emergencies. It is typically offered by various scuba diving organizations, such as the Professional Association of Diving Instructors (PADI) and the Scuba Schools International (SSI).

The Rescue Diver course builds upon the skills and knowledge gained in previous scuba diving courses, such as the Open Water Diver and Advanced Open Water Diver courses. It teaches divers how to identify and manage diving-related stress and how to recognize and respond to common diving emergencies, such as panicked divers, tired divers, and unresponsive divers. Participants also learn how to use specialized equipment, such as dive rescue buoys and oxygen delivery systems, to provide emergency care to injured or ill divers.

The course is typically divided into three parts: knowledge development, practical training, and scenario practice. During the knowledge development portion, participants learn about the principles of rescue diving, including how to manage diving-related stress, how to recognize and respond to emergency situations, and how to provide emergency care to injured or ill divers. During the practical training portion, participants practice these skills in a controlled environment, such as a pool or shallow water. Finally, participants complete scenario practice, where they respond to simulated emergency situations in open water under the supervision of a certified rescue diving instructor.

Upon completion of the Rescue Diver course, participants receive a certification card that is recognized worldwide and can be used to fulfill requirements for scuba diving certification or for other purposes, such as employment or volunteer work. The Rescue Diver course is an essential training program for anyone who wants to learn how to prevent and respond to diving emergencies and provide emergency care to injured or ill divers.
