The TDI Technical Divemaster Course is the first professional level certification in the TDI leadership levels.
During the Technical Divemaster training course you will be challenged and learn what it is like to work with divers as they begin or continue their technical diving experiences.
You will learn how to manage divers, work as land or boat support, and conduct enjoyable dives.
Dive physics, physiology, how to conduct pre-dive briefings, how to assist technical instructors as well as how to be a professional TDI Divemaster are all part of the course.
Your skills will be refined to demonstrate quality and your knowledge will be increased to that of a technical diving professional.
This course is for SDI Divemasters who are certified technical divers and want to assist with TDI Diver Courses and lead technical dives at the level they are certified to dive.
The Technical Divemaster training, provided by ScubaQuest, will certify students to the recognised international standards provided by Technical Diving International (TDI).

As your motivation to explore progresses you may find you wish to go deeper to dive that historical wreck or cave system that you have read so much about. Alternatively, you may just want to continue your journey and learn new skills and techniques.
One of the limiting factors of diving deeper is gas narcosis; TDI’s Trimix Technical Diver course shows you how to minimise the effects of gas narcosis by using helium in place of a percentage of the nitrogen in your breathing gas.
During the 4 day Trimix Technical Diver course you will be shown how to competently and safely utilise how to plan for dives using helium in the back-gas, the limitations of using helium and the impact of helium on decompression.
60 meters maximum using Trimix as back-gas – Oxygen content no less than 18%.
Utilising up to 100% oxygen for accelerated decompression.
The Trimix Diver Course is performance based.
The technical diver training, provided by ScubaQuest, will certify students to the recognised international standards provided by Technical Diving International (TDI).
The course is completed over four days with a minimum of four dives below the depth of 30m, two of which will be below 40m with a minimum accumulated bottom time of 100 minutes.
Due to the nature of the course a flexible and personalised approach to the schedule will be applied based on the previous experience and pace of the student.

As with the stepped philosophy that TDI training programmes implement, the Extended Range Technical Diver course serves to build on prior knowledge and skills to enhance your diving capabilities and leaves you qualified to take on more challenging and adventurous dives.
The Extended Range course will reinforce much of what has previously been learned, but will go into greater depth as well as introducing new concepts and ideas.
The course will provide the training and experience required to competently utilise air for dives down to a maximum of 55 meters, with staged decompression utilising up to 100% oxygen. The objective of the Extended Range programme is to train divers in the proper techniques, equipment requirements and hazards of deep air diving to this depth.
55 meters maximum using air as backgas.
Utilising up to 100% oxygen for accelerated decompression.

The Advanced Nitrox & Helitrox course is similar in nature to the Advanced Nitrox and Decompression Procedures course with all the same skills and a depth rating of 45meters but utilising enriched air nitrox and helium mixtures not exceeding 35% helium content or breathing less than 21% oxygen content.
This will give the diver a benefit as it pertains to gas narcosis, allowing the diver to dive to depth but without the full impediment of narcosis. There are also some additional equipment configurations to discuss and an additional theory component to the course as it pertains to helium use.
The Advanced Nitrox & Helitrox course is the ideal training for diving in Scapa Flow and many of the UK’s coastal wrecks.
Please note: Advanced Nitrox and Helitrox can both be taken as standalone courses in their own right. Please contact us if this is something you are interested in.

The Advanced Nitrox & Decompression Procedures course is the foundation course in technical diving.
All technical dive training taken after this course is completed builds on the skills and attitudes learned while undertaking the Advanced Nitrox & Decompression Procedures course.
The Advanced Nitrox & Decompression Procedures course examines the theory, methods, and procedures of planned staged decompression diving.
The course objective is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45m using staged nitrox up to 100% to accelerate the decompression.
This is the ideal course for diving in Scapa Flow and many of the UK’s coastal wrecks.

If you have got to this page you have probably done some research on Closed Circuit Rebreathers (CCRs), seen people diving them, are curious as to what they are all about or indeed maybe you have even had a go, if not it is something we can arrange for you
The reasoning behind using CCRs is many and varied, getting up close to wildlife for that award winning photograph, a love for technology, to extend your bottom time for wreck, cave or mine exploration or just for the sheer peace of diving without bubbles.
Whatever it is that has piqued your interest, this is the entry-level CCR course that will take you safely into the world of silent diving!
The focus of the CCR Air Diluent Diver course is to train divers in the benefits, hazards and proper procedures for diving a Closed Circuit Rebreather (CCR) and to develop core CCR diving skills to a maximum depth of 30 metres, using air as a diluent. Accelerated decompression diving is not allowed at this level of training.
Currently, all training is done using AP Inspiration XPD, EVP, EVO & Classic/IQSub XCCR/ScubaForce SF2 rebreathers.

During the past few years there has been an explosion in interest in the field of technical diving. Have you ever wondered why people jump into the water with so much complicated looking kit? Why do they do it? Where are they going? How do they manage it?
Well the objective of this course is to answer these questions, to give students an opportunity to familiarise themselves with technical equipment configurations that could, with the right guidance, get them comfortable in unfamiliar equipment and stop them from making expensive mistakes when it comes to equipment purchase and future-proofing themselves dependent on where they may see their technical diving journey going.
The course will also expand on the key skills learned on introductory level diving courses such as breathing, buoyancy control, trim, propulsion techniques and situational awareness. Finally, the Introduction to Technical Diving course introduces the student to advanced gas planning techniques within the no stop diving context.
The Introduction to Technical Diving course is excellent preparation for the next phase of training if the student chooses to progress to courses that involve decompression procedures techniques. However, this course can also be used from an experiential perspective with the added bonus of continuing to dive in the no-stop range, in a planned way with multiple tanks and with an excess of gas, which of course is never a bad thing.
No depth rating earned – experience programme only.
Completion with participation.
The technical diver training, provided by ScubaQuest, will certify students to the recognised international standards provided by Technical Diving International (TDI).
