GUE Technical Diver 2

Course Overview & Training Objectives

GUE Technical Diver 2 represents GUE's apex open-circuit qualification, authorizing exploration to 75m (245ft) and beyond with hypoxic trimix. The program trains divers to safely handle hypoxic bottom gases unbreathable at the surface, mandating off-board travel gas deployment during descent and ascent. The curriculum focuses on extreme gas logistics, deep team coordination, isobaric counterdiffusion avoidance, and fault-tolerant emergency recovery under heavy decompression stress.
