GUE Doubles Primer

Transition to Double Tanks

GUE Doubles Primer is a practical course for divers who want to move from a single tank into a double-tank configuration with control and comfort. GUE explains that longer dives, greater depths, and more advanced environments often require increased breathing-gas volume and added equipment redundancy. The course is designed to teach proper equipment use and the basic skills needed to dive doubles safely rather than simply adding more gear to the same habits.

The primer is useful for anyone preparing to transition into doubles, including divers planning to take GUE Fundamentals without previous doubles experience. GUE notes that it is available to non-GUE trained divers and can serve as an introduction to GUE systems. Applicants must be at least 16, fit for diving, able to swim, non-smoking, medically cleared when needed, and certified at least as autonomous entry-level scuba divers through a recognized agency.

Training outcomes include buoyancy and trim practice, skill refinement, understanding and using the double-tank configuration, GUE equipment configuration, and basic valve management. GUE describes the course as normally one day, with at least two dives and eight hours of classroom, land-drill, and in-water instruction. At Extreme Exposure in High Springs, Florida, Doubles Primer is a smart stepping stone for divers preparing for Fundamentals, deeper recreational courses, or eventual technical and cave pathways.
