Course Outline


The vast majority of the skills learnt in the first two days will give you a sound understanding of the equipment you will use for your technical diving and the associated skills to handle emergencies effectively underwater. 

From day three the emphasis will be on learning how to conduct safe simulated and live staged decompression. You’ll further develop your skills learnt in the previous two days culminating with a planned, live accelerated decompression dive to your maximum depth.


We appreciate it's a bit of a minefield as to what agency will work for you, we train in three... 

RAID - Deco 40 - (Four to five days) Can be conducted in a twinset OR a single cylinder, long hose with ability to utilise trimix! If you not only have deep diver and nitrox but also Rescue Diver as a prerequisite you can proceed straight to the RAID Deco 50 course without having to complete this level ! On-line course materials which are most up to date in our opinion with lifetime access to updates. 


PADI - Tec 40 - (Four to five days) Can be conducted in a twinset OR single cylinder.

TDI - The course is broken down into two parts:

  • Advanced Nitrox Course - (Two days) course to be completed in twinset.

  • Decompression Procedures - (Two to three days)  


  • Deep diver with nitrox qualification

  • 18 years of age.

  • 25 – 40 dives, agency dependent.


 Knowledge Development

During the course we will conduct dedicated theory sessions to assist you in completing your home study (RAID - Online, PADI/TDI - Paper manual).

 Open water dives

  • Depending on the agency, you may have to do a confined water session.

  • Six to eight open water open water dives.

 What is not included?

Travel to and from the training locations and open water sites are your responsibility. The training normally culminates at NDAC Chepstow and there is an entry fee per student per day payable directly to the centre. We can also use various other open water sites, weather & depth dependent and we also have access to hard bottomed boats & RIBs should you prefer but these carry an extra fee payable to the boat skipper. You will be required to have your own drysuit for the course unless we complete the course at an open water site in the UK in summer should you wish or abroad. Any further equipment you require, we can hire this to you at a reasonable cost, including a fully rigged twinset complete with backplate, harness wing and tec regs!

 What’s next?

Once you’ve completed your entry level technical course whether in RAID, TDI or TecRec it’s time to rack up your experience and get in some technical diving before progressing onto a level 2 (normoxic trimix course). Alternatively, you might realise that trimix is expensive and if you’re intending in doing a lot of it, perhaps a rebreather is the answer, talk to us!
