GUE Technical Diver 1

Conscious technical diving, equipment failures management, teamwork, normoxic trimix and standard decompression gases.

GUE Technical Diver 1

Technical diving requires an appropriate level of awareness, skills and equipment.

Our goal is to provide you with enough knowledge and skills so that you can focus on the task at hand during trimix dives, while maintaining situational awareness and safety.

With a big dose of decompression theory, you will learn how to plan, simplify and perform pragmatic decompression – an intuitive, predictable way that gives the diver a lot of freedom and flexibility.

A key component of the GUE Technical Diver 1 training is becoming proficient in equipment failures management. Bottom or decompression gas leaks, light failures or mask damage are serious situations that pose a real risk in technical diving conditions. During the Tech1 course, we emphasize building equipment and team awareness to identify and consciously respond to various failures.

Another advantage of the GUE Tech1 course is developing the ability to deal with high task overload. In this course, you will learn how to deal with multiple challenges at the same time – both in the context of your individual skills, as well as your team efficiency. The ability to solve equipment problems, while maintaining buoyancy control, navigation and team communication, is a characteristic of truly capable and responsible technical divers.

Completion of the GUE Technical Diver 1 training provides you with competencies essential for more advanced and complex project dives. In addition, the Tech1 certificate makes it easier and faster to enter the technical diving path on a rebreather – after passing GUE CCR Fundamentals training.

Limits during the training:

  • Maximum depth: 51 m.
  • No overhead environment.
  • The planned decompression must not exceed 30 minutes. Planning is carried out using the GUE DecoPlanner software.

Each GUE course includes a swimming test. In this case, it is:

  • 375m swim in up to 14 minutes.
  • 18m underwater on a held inhale.

The theory in the GUE Technical Diver 1 course is a comprehensive preparation for technical diving. The program combines advanced knowledge with a hands-on approach to planning and executing dives using different breathing mixtures.

During the classes, you will learn in detail about issues such as:

  • Physiology of diving with trimix and nitrox mixtures – the impact of various respiratory gases on the body and ways to minimize the risk.
  • Manage the available amount of breathing gases depending on the specifics of the dive in question.
  • Decompression – Decompression theory, pragmatic decompression and the use of the GUE Deco Planner software.
  • Decompression sickness and arterial gas embolism – mechanisms, causes, first aid and prevention.
  • Hands-on dive planning and emergency procedures.
  • Team procedures – key principles of communication and cooperation underwater.
  • Standard gases: optimal use and selection of mixtures for given diving conditions.
  • Risk management and critical thinking – analysis of potential emergency situations and effective response methods.

Each element of the course has been designed to not only convey knowledge, but also teach its practical application in real conditions.

GUE Technical Diver 1 training is focused on practical skills. During the course, we work in several key areas:

  1. Warm-up after Technical Fundamentals and optimization of the configuration (twinset + side stage tank).
  2. Teamwork, line laying, solving equipment failures, including failures of regulators, valves, lights, masks.
  3. Rescue skills in technical diving.
  4. Decompression procedures (pragmatic decompression, emergency decompression procedures).
  5. Verification of acquired knowledge and skills: planning and performing at least three dives to a depth of 40-51m.

As in all GUE trainings, new skills are discussed, shown and practiced in detail before entering the water.

In addition to preparing for technical diving, the GUE Technical Diver 1 training increases project diving competences (wreck exploration, Ghost Diving, etc.).

Where do GUE Tech1 trainings take place?

It largely depends on you. We teach in various places in Poland and abroad. The GUE Technical Diver 1 course in Poland usually consists of training sessions in the Bay of Gdansk and/or in lakes combined with trimix dives on Baltic wrecks. We can also carry out this training in warmer waters – for example, in Croatia, Spain, Italy or Egypt. If you have your own idea for a diving destination that you want to combine with training, let us know – we will come up with something 🙂

Am I ready? I don't know how to prepare.

If you have completed the GUE Technical Fundamentals course, you have the necessary foundations to start the Tech1 training. To prepare well, it is advisable to revise all the skills and procedures in the Fundamentals area, such as buoyancy, trim, movement techniques and procedures – especially the s-drill and v-drill. In the Tech1 course, we will develop new skills that require proficiency in these areas.

Why "only" 51m?

When using one of the most popular twinset configuration (2x12L doubles) and taking into account the necessary reserves, diving to greater depths without additional bottom gas is very short. During the training, you will learn how to solve underwater problems and how to perform dives that have a specific goal – e.g. finding/documenting specific fragments of the wreck. At greater depths, there is simply not enough time for this. Deeper does not always mean better :). If you are planning to dive to greater depths – GUE Tech2 or CCR2 training will be an excellent next step.

Why "only" one decompression cylinder?

In this range of depth and bottom times, the introduction of a second decompression gas only slightly reduces the decompression time and at the same time increases the risk of confusion. During the Tech1 training, you will master handling one decompression cylinder, the gas switch procedure and applying pragmatic decompression protocols. More cylinders will be introduced in the GUE Tech 2 or CCR 2 training, where the depth and longer decompression time require the use of 2, 3 or more stage cylinders.

Will we use the "ratio deco" method in planning and performing dives?

GUE does not use the ratio deco as a stand-alone method of decompression planning. While some of the principles of this concept may be helpful in quickly estimating a dive profile, it is not the main or only method of our decompression planning.

During the GUE Tech 1 training, you will learn pragmatic decompression, i.e. planning and executing dives based on the GUE Deco Planner software, while using simplifications that make it easier to remember and adapt the decompression plan to the circumstances of a given dive.

During the course, you will also learn about the key risk factors, which are as important as the diving profile. You will learn what to look for and how to modify your dive plan to increase its safety.

Ratio Deco will only be an interesting add-on that is worth to know and understand.

What are the further training opportunities after the GUE Technical Diver 1 course?

The first step of the course will be to gain experience in technical diving. We especially recommend taking part in GUE Projects, which are organized in various places – also by us.

When it comes to the next trainings available after the Tech1 course, you have a few options:
