GUE Technical Diver

GUE Technical Diver: Level 1
“Full tec trimix training”

The GUE Tech 1 course is normally conducted over a very intense 6 day period. Combining lectures and practical (inwater) sessions, this course is designed to introduce students to GUE technical diving concepts and build competence in important areas such as gas switching and ascent management.


The course starts in shallow water and concludes with three experience dives in the 40–50m range. Much of the in-water section of the class focuses on emergency management scenarios, all conducted in actual dive settings. Your capacity to deal with the wide variety of potential problems encountered whilst ‘tech diving’ will be tested and ultimately expanded and improved.

Skills The GUE Tech 1 course covers all the essential skills required to dive safely in the 50m depth range: valve failures, gas switching procedures, ascent protocols, out-of-gas and lost deco gas emergencies, basic line protocol, SMB deployment, team communication and diving protocols.
