For divers wishing to progress beyond the limits of recreational diving, GUE offers comprehensive training that will prepare you for the rigours of technical diving.

Building upon the solid foundations laid down in the GUE Fundamentals class, you'll develop the skills, procedures and knowledge to undertake dives requiring mandatory decompression using standardised breathing mixtures and decompression gases. You'll gain a greater understanding of effective decompression and gas management strategies and learn how to apply them to your own diving. Particular focus is placed on developing a diver with a problem solving mentality who can safely and competently manage common issues underwater using an effective team-based approach.

The GUE Technical Diver training system builds upon each course in a structured and logical way that encourages divers to consolidate new skills and theory at a pace that suits them before progressing onto the next, more advanced level of training.

GUE Technical Diver 1
The foundations of better diving
The GUE Tech 1 course prepares ambitious divers to begin their path to technical diving safely, with confidence, and with a base of solid skills and knowledge.

This course also paves the way to GUE rebreather courses, to advanced technical GUE training, and to GUE project and exploration diving.

The Technical Diver Level 1 course requires a certification at GUE Fundamentals level with technical certification requirements and a minimum of 100 experience dives.

Divers embarking on a technical path must be prepared to handle emergencies and execute dives during which they will not be able to make a direct ascent due to decompression obligations. This type of diving requires an increased level of physical fitness, as there is more equipment to handle, and decompression stress is increased.

Course outcomes include, but are not limited to: cultivating, integrating, and expanding the essential skills required for safe technical diving; identifying and resolving problems; using the double-tank configuration and addressing the potential failure problems associated with doing so; using nitrox for acceleration and general decompression strategies; using helium to minimize narcosis; and applying single decompression stage diving with respect to decompression procedures.
GUE Technical Diver 2
The foundations of better diving
Advanced underwater missions beyond 50 m/170 ft require a robust skillset, extensive experience and in-depth knowledge, as well as resilience to handle potential difficulties at greater depths.

These dives can be exciting, as many of the undiscovered and unexplored areas are beyond the limits of recreational or even level 1 technical diving limits. Being proficient with dives at these depths will open the doors to project diving, exploration, and discoveries even further for all those who want to accept the challenge.

GUE’s Technical Diver 2 course is designed to enhance deep diving proficiency while using helium breathing gases and oxygen-enriched decompression gases.

It is a rigorous class designed to prepare divers for depths of 75 m/246 ft and beyond, using multiple (three or more) stages or decompression gasses, to manage their gas, bottom time, and decompression exposure in a safe and comfortable manner.

Course outcomes include, but are not limited to: the use of multiple stages; the use of trimix with greater percentages of helium; the use of hypoxic gas mixtures protocols; gas management; oxygen management; extended decompression; accelerated, omitted, and general decompression strategies; dive planning; and management of multiple cylinders.
