GUE
Last updated September 7, 2026
Global Underwater Explorers teaches a standardized, team-based approach to diving (rooted in the "Doing It Right" equipment configuration) that starts every diver — recreational or technical — with the same Fundamentals course before branching into cave, technical, CCR, or DPV progressions. The emphasis throughout is on consistent gear, procedures, and team protocol so any two GUE divers can dive safely together.
