Run over 2 days there is no requirement to achieve significant depth progression so we can focus on core skills. As you will generally be new to your equipment we begin with a dry session sizing and configuring your equipment to your needs (we can help with equipment supply). The dry session will also include a run through of skills, trim and propulsion advice.

Core development is centred-around making sure you have a stable platform in the water, out of air drills, valve shutdown procedures and DSMB deployment.

Entry requirements are Rescue Diver (or equivalent) and above with experience of 30m (ish) diving.

This is an excellent foundation to further twinset technical training.

This course is designed to take the recreational diver not accustomed to decompression diving or the diver with limited-decompression diving and introduce a deco/stage cylinder to increase the speed and efficiency of that decompression.

You will cover twinset diving techniques, deco/stage cylinder handling, out of gas scenarios, loss of decompression gas, decompression techniques, dive planning and much more.

Running over 3 or 4 days and resulting in either a 42m or 45m qualification (IANTD/TDI) you will be well placed to enjoy masses of diving. Skills learnt here will be the foundation for wherever your diving takes you.

Entry requirements are Rescue Diver and above with basic Nitrox (or equivalent) and experience of 30m diving.

This course will push beyond the limits of the Advanced Nitrox program utilising helium-based mixtures to reduce narcosis and a deco/stage cylinder to improve and accelerate the decompression.

You will cover twinset diving techniques, deco/stage cylinder handling, out of gas scenarios, loss of decompression gas, decompression techniques, dive planning and much more.

Running over 4 or 5 days we begin with classroom and equipment preparation before moving onto shallow skills dives and depth progression. Successful completion will certify the diver to dive to 51m.

Entry requirements are Rescue Diver and above with basic Nitrox (or equivalent), familiarity with 30m diving and some twinset experience.

In many ways this course makes more sense than the Advanced Nitrox course, if you are new to twinset diving a good option is the Self Sufficient course followed by Advanced Recreational Trimix.

Whilst open circuit trimix diving is less common than it used to be, it is still a great choice for divers planning occasional deep trimix dives. If you are planning extensive diving in this depth range then please talk to us about rebreather options.

Diving at this level will require carrying a second deco/stage bottle therefore initial skills focus on managing extra equipment and procedures whilst perfecting core twinset techniques, out of gas scenarios, loss of decompression gas, decompression techniques, dive planning and much more.

Running over 5 or 6 days it is possible to complete training at the Normoxic 60m level or the Normoxic + 70m level. Training begins with classroom and equipment preparation before quickly moving into shallow skills dives and depth progression.

Entry requirements are Advanced Nitrox, Advanced Nitrox & Deco Procedures, Advanced Recreational Trimix or equivalent with experience at that level.
