Open Circuit

Advanced Nitrox 

Our Advanced Nitrox course would be great for you if you are looking to continue your diver education and utilise enriched air nitrox as a breathing gas to extend no-decompression limits at depth, extending your bottom time & increasing your technical diving education. 

You will learn the benefits, hazards & proper procedures for using nitrox mixes from 22-40% oxygen content. Also, cylinder labelling, analysing nitrox mixtures and gas blending procedures.

Decompression Procedures

Nuttys Decompression Procedures course will prepare you for planned staged decompression diving, with a maximum operating depth of 45 metres/150 feet, this will be your first step beyond the normal sports diving limits.

Your course will teach you, decompression dive planning including – decompression gas choices & emergency and contingency planning, and much more!

Extended Range 

The Extended Range course is for those certified Advanced Nitrox / Decompression Procedures diver who’s looking for their next step into Technical Diving. Your course will teach you the proper techniques for utilizing compressed air as a breathing gas, and with a maximum depth of 55 metres / 180 feet.

Your course will teach you proper techniques, equipment requirements, the hazards of deep air diving & to compentently utilize air for dives up to 55 metres / 180 feet that require staged compression using nitrox mixtures or oxygen during compression. 

Trimix

 If you are looking to expand your depth range and reduce narcosis during deep dives then this is the course for you! One of the major factors of diving deeper is narcosis, our Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. 

Your course will teach you advanced decompression dive planning, decompression dive procedures management of multiple decompression/stage cylinders & much more.

Advanced Trimix 

Our Advanced Trimix course is the top level of training for open circuit divers. If you are wishing to dive to depths as deep as 100 meters / 330 feet using hypoxic levels of oxygen (below 17%) then this is the course for you. 

You will larn various advanced decompression dive planning and procedures, management of multiple (minimum of 3) decompression/stage cylinders, cylinder labelling, analyzing trimix, nitrox and mixes, and much more.
