GUE TECHNICAL DIVER 1 The gold standard

The gateway to GUE Project Exploration; the standard for Technical diving 

The GUE Tech 1 course is recognised worldwide as one of the most demanding diving courses out there and earning the rating is an indisputable mark of excellence as a Technical diver. Upon completion you will be qualified to dive to 51m on Trimix with a single decompression cylinder having demonstrated a mastery of teamwork, problem-solving ability, awareness, ascent speed and timing and competency to handle any failures that could come your way.

Why take this course?

This class is designed for holders of a current GUE Fundamentals Tech Pass rating to enter the world of Technical diving, as well as those existing ambitious technical divers who have also fulfilled the Tech pass prerequisite to test themselves and gain a gold standard and sought-after qualification.
