Lots of people fly but very few are fast jet pilots. Many people dive, but again, very few venture into the world of technical diving. Whether your want is deep wreck diving, deep wildlife diving, cave/cavern or mine diving, open circuit or closed circuit rebreathers, invariably depth will become a consideration as will the associated planning needed to undertake this type of diving.
With ScubaQuest, the approach to teaching technical diving is one where courses are organised to fit with your schedule so that you get the most out of the course. In technical diving the learning experience is greatly enhanced when a team of students can be coordinated.
If you are interested in technical diving then take a look at the courses offered by Scuba Quest and please get in touch for a discussion. ScubaQuest are confident they can meet your expectations and deliver an experience which match your ambitions and allow you to reach your next diving goals.
TDI Introduction to Technical Diving
Course
Codes NDAC-TDI-ITT
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 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 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.
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.
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 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.
As with the stepped philosophy that TDI training programmes 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 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 programme is to train divers in the proper techniques, equipment requirements and hazards of deep air diving to this depth.
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 back-gas, the limitations of using helium and the impact of helium on decompression.
If you have got to this page you have probably done some research on Closed Circuit Rebreathers (CCR’s), 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 CCR’s 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 this course is to train divers in the benefits, hazards and proper procedures for diving a 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.
This is the certification course for divers wishing to utilize a Closed Circuit Rebreather (CCR) for air diving.
The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop core CCR diving skills to a maximum depth of 45 metres, using air as a diluent for formal decompression diving.
This is the second entry level certification course for divers wishing to utilise
a Closed Circuit Rebreather (CCR) for mixed gas diving using a Helitrox diluent.
The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 metres, using an air/nitrox/helium diluent for formal decompression diving.
Students are permitted to utilise Enriched Air Nitrox and Helium mixes with no greater than 35% Helium content, and up to 100% oxygen for decompression diving provided the gas mix is within their current certification level. Breathing gas mixtures containing more than 35% Helium or less than 21% oxygen are not permitted.
Note 1 – 4 dives are required, 2 of those dives must be deeper than 30 metres.
Note 2 – If Advanced Nitrox is taught in conjunction with Helitrox, a minimum of 6 dives are required. Check out the Advanced Nitrox and Helitrox course.
TDI Close Circuit Rebreather Helitrox
Crossover
Note 1 – If a student already qualified as TDI Helitrox Diluent Decompression Procedures CCR Diver or equivalent from agencies recognised by TDI and wish to qualify on another CCR recognised by TDI, the student must follow all unit specific course standards with the exception of:
A – Minimum of 60 minutes confined water training to a maximum of 9 metres.
B – Minimum of 240 minutes open water training to be completed over a minimum of 4 dives to a maximum of 45 metres with two dives deeper than 35 metres.
Upgrades
Note 1 – If a student has already qualified as a TDI CCR Air Diluent, or equivalent, certification and wishes to do the Helitrox decompression part of this course, only 240 minutes open water are required. Students will complete a skills evaluation dive plus a minimum of 4 open water dives with two dives deeper than 35 metres.
Note 2 – The student needs to have a minimum of 30 logged hours over 30 dives before enrolment on the Helitrox deco course
Note 3 – Six months CCR diving experience
Note 4 – If a student has the TDI CCR Air Diluent Decompression certification and wishes to do the Helitrox decompression part of this course, only 120 minutes open water are required over a minimum of two dives, with both dives deeper than 35 metres.
