GUE COURSES

The GUE Fundamentals course is by far GUE’s most popular program. It functions as a gateway into GUE training and it is an excellent way to personally experience what GUE is all about.

Many technical divers and even experienced instructors from other organisations use the course to improve basic skills and gain access to GUE’s cave and tech-training. Everybody will benefit, regardless of their current level of certification or experience. Graduating this course with a pass is something to be proud of, as the quality of a GUE Fundamentals diver is recognised all over the diving world.

The GUE Fundamentals course provides all divers with an opportunity to advance basic diving skills. It provides the non-GUE trained divers (divers who are already certified with another recognized diving agency) with a gateway into GUE training.

It is a prerequisite for all GUE courses (apart from entry-level courses, Drysuit and Doubles primers).

Scrupulous care is taken in the selection and training of our instructors to ensure the best possible experience for all students. GUE instructors must possess exemplary diving skills and knowledge in addition to effective communication and teaching skills.

Instructor Training Programs

Becoming a GUE instructor can be a long and demanding process, as is confirmed by the small group that has been able to reach the high bar we have set. This is not only due to the intense instructor requirements but also to the regular renewal and re-qualification requirements for all instructors.  On a yearly basis, every GUE instructor must pass a fitness test and demonstrate both teaching and diving currency at the highest levels of their qualification. While this might seem obvious, it is one of many GUE innovations. In this case, GUE remains the only agency willing to accept the financial cost of fewer instructors while ensuring diving currency and capacity from their instructors.
