Some recreational level courses are quite basic in the sense of being aimed at getting on a rebreather, this is a course designed to teach you how to dive a rebreather and to prepare you for technical level training should you decide to pursue this style of diving. It is possible to take this course in conjunction with a technical level; it makes for a longer program but is a popular option.

This course is also popular with underwater photographers and filmmakers looking for the benefits of silent diving and longer dive times rather than attaining deeper depths.

Entry requirement for this level is IANTD Advanced Nitrox or TDI Advanced Nitrox/Deco Procedures and above or equivalent. Training at this level will retain limits of the above qualifications but apply them to rebreather diving.

This is a busy course; expect full days, lots of information and a minimum of 8 hours in the water. The course will breakdown into classroom theory sessions, equipment preparation/maintenance, dry diving skills and in water time.

The aim of this course is to give you a solid foundation as a rebreather diver, allow the confidence to enjoy your diving within your certification limits and build your experience towards progression to the next level, be that trimix or overhead environment.

Successful completion of this level will give the diver the skill set to go off and enjoy fantastic diving, locations such as Scapa are brilliant for building hours and excellent preparation for mod 2. This course (plus the requisite hours) meets the requirements for mod 2.

Entry requirement for this level is IANTD Advanced Recreational Trimix or TDI Helitrox and above or equivalent. Training at this level will retain limits of the above qualifications but apply them to rebreather diving.

It is also possible to take this course rather than the traditional mod 1 above or indeed as an add on module to the recreational rebreather programme (probation hours are required for full cert), both make for an extended programme, please contact us to discuss which option suits you best.

Entry requirements for this level are IANTD or TDI rebreather/mod 1 (including deco - recreational rebreather does not meet the requirement) or equivalent plus minimum hours. Training at this level will qualify divers to complete dives to 60m (70m with IANTD Normoxic +) carrying bailout cylinders.

The course is 5 days (6 with normoxic +). We begin with a classroom and equipment preparation session. Dive one is always a recap of the core skills - think 'mod 1 in a dive'. Progression is then made both in terms of depth and skills that offer a broader range of options to keep your CCR working. Your understanding of what is going on in your rebreather will take a huge leap forward in comparison to your mod 1 knowledge.

Dive planning features heavily and is compared to real world scenarios. We want you to come and enjoy the great diving that this certificate can open up to you. Think Malin Head, Norway, classic wrecks of the English Channel, the Great Lakes and the deeper wrecks of Truk Lagoon to name but a few.

Entry requirement for this level is IANTD or TDI Normoxic trimix/mod 2 or equivalent plus minimum hours. We very rarely run combined mod 2/3 programmes. You should be comfortable diving your rebreather in the normoxic range prior to enrolment; this is not a course that should be used as a 'rebreather refresher'.

Run over 5 days, we begin - as always - with a skills review and then quickly move into dives pushing beyond the Normoxic/Mod 2 level. Emphasis is firmly placed on keeping your rebreather running after a significant failure at depth. Manual oxygen control from depth, semi-closed mode (with and without electronics) and deep bailout are core skills. You will be carrying 3 bailout cylinders throughout the course.

Wherever possible you will be diving real dive sites in real conditions - we aim not to run this course at an inland site.

Expedition logistics are always a headache and spending time going through potential options for you and your forthcoming dives is a key part of what we do. The world really is your oyster as a Hypoxic Trimix diver, enjoy!

Entry requirements are rebreather diver (Adv Nitrox/Adv Rec trimix) or above. You really want to be comfortable on your unit prior to training. Even if you are an experienced rebreather diver, we recommend that you seriously consider undertaking the IANTD Essentials programme to ensure that core skills are squared away before you start this course.

Running over 5 days we use wrecks that are as 'stable' and 'wide open' as possible for training. This allows you to enjoy an environment that is testing but also controlled enough for teaching. The Maltese purpose sunk wrecks are an excellent example of the sorts of wrecks used for this course.

Skills will include buoyancy, trim, propulsion, line laying/retrieval, lost line, lost diver, zero visibility exits, out of gas diver…

We are wreck divers and recognise that many wrecks that you dive will not allow a full blown approach to the dive as one of these training dives might, however we do believe these skills gained whilst 'doing it right' will stand you in good stead for your wreck diving adventures.
