GUE Fundamentals of Better Diving

The DIR Fundamentals course is designed to cultivate the essential techniques required by all sound diving practice, irrespective of level or environment. Poor diving skills and inefficient equipment often result in unnecessary exertion, stress, degradation of the dive site, and thus less enjoyment. Functioning as a prerequisite for all other Flatirons Scuba technical classes as well as other GUE classes. DIR Fundamentals performs a three-fold function within the GUE curriculum: 1) it provides the recreational diver, in whom there is no desire for further diver training, with a context in which to advance his/her basic diving skills, thereby developing more comfort, confidence, and competence in the water; and 2) it provides the diver with aspirations of more advanced diver training with the tools that will contribute to a greater likelihood of success; and 3) it provides non-GUE trained divers with a gateway into GUE training.
