General Information

We are pleased to offer the following range of Technical Courses, with something for everyone from the enquiring diver interested to know more about Tech diving, to the more experienced diver who wishes to expand their knowledge and experience.
 
TDI Intro to Tech
 
The objective of this course is to answer 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 purchases and futureproofing themsleves dependent on where they may see their techncial 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 course introduces the student to advanced gas planning techniques within the no-stop diving context.
 
The course is excellent preparation for the next phase of training if the student chooses to progress to courses that invlove decompression procedures techniques.
 
However, this course can also be used from an experiential perspective with the added bonus of contunuing 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.

TDI Advanced Nitrox and Decompression Procedures Course

This 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 this course. The 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.

PLEASE NOTE: Advanced Nitrox and Decompression Procedures can both be facilitated as standalone courses in their own right. Please contact us if this is something you are interested in (£300 per course).

Qualification Depth

45 meters maximum utilising up to 100% oxygen for accelerated decompression

Course is performance based

Duration

4 days, (minimum 6 dives)

Cost

£525

Includes: Manual, certification, use of 02 analyser, twinset, regulators and stages

Excludes: Site entrance fees, gas fills, equipment hire (canister torches, SMB’s, slates etc.).

Previous Experience/Notes

Minimum Age: 18

Logged dives: Proof of 25 logged dives

Minimum qualifications: Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent

TDI Advanced Nitrox and Helitrox

This 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 20% helium content or 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 a additional theory component to the course as it pertains to helium use.

Breathing gas mixtures containing more than 20% helium and less than 21% oxygen are not permitted.

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 (£300 per course or £150 for Helitrox upgrade if already a Decompression Procedures diver or equivalent).

This is the ideal course for diving in Scapa Flow and many of the UK’s coastal wrecks.

Qualification Depth

45 meters maximum

Breathing gas mixtures cannot contain more than 20% helium or less than 21% oxygen

Utilising up to 100% oxygen for accelerated decompression

Course is performance based

Duration

4 days, (minimum 6 dives)

Cost

£525

Includes: Manual, certification, use of 02/He analyser, twinset, regulators and stages

Excludes: Site entrance fees, gas fills, equipment hire (canister torches, SMB’s, slates etc.).

Previous Experience/Notes

Minimum Age: 18

Logged dives: 50

Minimum qualifications: SDI Advanced Diver (or equivalent) with Deep Speciality or TDI Intro to Tech

Must be certified as TDI Advanced Nitrox Diver to undertake Helitrox course.

TDI Extended Range

As with the stepped philosophy that TDI training programs implement, the Extended Range courses 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 course will reinforce much of what has previously be 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 utilize air for dives down to a maximum of 55 meters with staged decompression utilising up to 100% oxygen. The objective of the program is to train divers in the proper techniques, equipment requirements and hazards of deep air diving to this depth.

Qualification Depth

55 meters maximum using air as backgas

Utilising up to 100% oxygen for accelerated decompression

Course is performance based

Duration

3 days, (minimum 4 dives below the depth of 30m, 2 of which below 40m with minimum accumulated bottom time of 100 minutes)

Cost

£510

Includes: Manual, certification, use of 02 analyser

Excludes: Site entrance fees, gas fills, all equipment hire

Previous Experience/Notes

Minimum Age: 18

Logged dives: proof of 100 logged dives (25 of which must be deeper than 30 meters)

Minimum qualifications: TDI Advanced Nitrox and Decompression Procedures (or equivalent)

TDI Trimix

As your motivation to explore progresses you may find that you wish to go deeper to dive that historical wreck or that 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 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 this 4 day course you will be shown how to competently and safely utilise how to plan for dives using helium in the backgas, the limitations of using helium and the impact of helium on decompression.

Qualification Depth

60 meters maximum using Trimix as backgas (Oxygen content no less than 18%)

Utilising up to 100% oxygen for accelerated decompression

Course is performance based

Duration

4 days, (minimum 4 dives with a minimum accumulated bottom time of 100 minutes, 2 of which below 40m)
