GUE
A US 501(c)(3) nonprofit diving organisation that trains recreational, technical and cave divers using its own defined equipment configurations and supports exploration and conservation projects.
Global Underwater Explorers describes itself as a 501(c)(3) nonprofit that combines diver training with support for exploration, conservation and scientific projects [1]. GUE publishes excerpts of its General Training Standards, Policies, and Procedures for each course, which makes its cave course limits unusually easy to check [2][3].
GUE's cave track starts only after its Technical Fundamentals course. Cave 1 covers limited-penetration cave diving with one permanent intersection allowed and no decompression; Cave 2 adds complex navigation, stage cylinders and decompression [2][3]. Specialities that build on Cave 2 include DPV Cave, Underwater Cave Survey and CCR Cave [4][5][6]. GUE runs an online instructor locator [1].
