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.
Please note: Advanced Nitrox and Helitrox can both be taken as standalone courses in their own right.
Please contact us if this is something you are interested in.
This is the ideal course for diving in Scapa Flow and many of the UK’s coastal wrecks.
