FUNDAMENTALS Course 
The Gue Fundamentals course is the agencie’s most popular program and serves as an introduction to its training. It helps divers improve on prior training, gain access to GUE projects, or refine skills for tech and cave training. Divers from various backgrounds join the course, making it unique in the industry. Regardless of experience or certification level, all participants benefit from it, and graduation with a Tech Pass is a significant achievement.
