The cost of a GUE class can vary, as GUE HQ does not set guidelines as to what instructors are required to charge. The only fee that we require to be paid directly to HQ is the registration fee, which gives you access to your class materials and allows you to apply for a class. This fee covers the cost of those materials, processing, and certification. This fee varies from $45 for non-certification classes (GUE Primer, Doubles, or Drysuit Diver) to $95 for foundational training (including GUE Fundamentals and the Recreational Diver track) to $125 for advanced training (including the Cave Diver and Technical Diver tracks).
The registration fee charged by GUE HQ is separate from any course fees charged by your instructor and covers the cost of those materials, processing, and certification. This fee varies based on the class you are taking:
  • $45 for Doubles or Drysuit Primer (no certifications) and Gas Blender.
  • $40 for GUE Fundamentals Part 1.
  • $55 for GUE Fundamentals Part 2.
  • $95 for GUE Fundamentals, Recreational Diver 1, 2, and 3, Documentation Diver, DPV 1 and DPV Cave.
  • $125 for Underwater Cave Survey, CCR, and Rebreather Diver.
  • $150 for Cave 1 and 2, Tech 1, 60, and 2.
The first step towards registering for a GUE class is to verify with your instructor that there is a spot reserved for you. GUE HQ (and thus our web site) does not substitute for direct communication with the instructor concerning class availability.


The next step is to create a free account on the GUE website and complete your Student Profile, located on the right-side user menu. Once you have done this, you can find the class you want to take by clicking on "Diver Training" in the top menu, then on "View Course Schedule." Once you find the class you wish to sign up for, you will be prompted to pay the registration fee. Paying the registration fee means that you apply for the class directly, and your instructor will be notified.

GUE Fundamentals training is an immensely popular course, affecting the way many individuals think about Scuba diving. Initially GUE Fundamentals was structured to prepare divers for the rigors of technical diving and was established as a pre-requisite for this training. However, most difficulty in diving relates to poorly developed fundamental skills; therefore, GUE began to promote this course to a broader community. Divers around the world have embraced this training as a way to greatly improve the safety and fun within their diving.


GUE Fundamentals may be conducted in single tanks for recreational divers; technical divers interested in advanced GUE training will use twin tanks. To enter GUE Fundamentals individuals must hold an Open Water rating from a recognized agency (most major agencies are acceptable). GUE training focuses upon the fundamental skills including theory and practical application of buoyancy, trim, teamwork, rescue skills, Nitrox, breathing gases, gas consumption, dive planning, equipment configuration, decompression theory and more. GUE Fundamental dives are video-recorded and used as a teaching tool to help improve diving skills.


You can learn more about GUE Fundamentals on its course page or in the GUE Standards.
