DIR, an acronym for "Doing It Right", is a holistic approach to scuba diving originally developed by members of the Woodville Karst Plain Project. Its classes are taught by Global Underwater Explorers. Some of the defining characteristics of DIR diving include an emphasis on fundamental skills, teamwork, environmental awareness, and the use of highly optimized and streamlined, yet simple and versatile, equipment configuration. The aim of the DIR approach is to improve safety by standardizing equipment configuration and procedures for preventing and dealing with emergencies, and out-of-air emergencies in particular. The DIR approach encompasses aspects of equipment choice and configuration, diving procedures and techniques, and diver fitness and preparedness.

Rationale
One of the challenges of scuba diving is that entry-level, recreational diving courses taught by large commercial firms can, in some opinions, tend to rush students through the training. This often results in divers who have not successfully mastered basic diving skills, such as buoyancy control. This in turn can make their dives more stressful and less enjoyable. On the other hand, DIR diving methodologies were developed to suit cave diving in northern Florida, yet are well-suited for even the recreational open water diver. By emphasizing "basic" skills, student divers are equipped with the necessary means to become truly comfortable, confident and competant divers.

In DIR, there is also the concept of "muscle memory" in that frequent practice of critical skills will bring a reflex action to emergency situations.

DIR diving blends safety, preparedness, teamwork and a robust equipment configuration. DIR is often seen as an equipment system alone, but it also encompasses a general philosophy or attitude of how to approach scuba diving. Students of DIR work to master the fundamentals of diving. An example is the DIR approach to team diving, where the diver's buddy is actually a team member and more focus is placed on underwater communication. This makes separation much less likely, which in turn results in a less stressful, more enjoyable dive.
