SSI ENRICHED AIR NITROX COURSE $250
Or just $180 if combined with a SSI Advanced Adventurer course or even Wreck or Deep Diver course
Stay down longer with an Enriched Air Nitrox Course
Nitrogen, you learned about it as an Open Water Diver, then again as an Advanced Open Water diver. You started to understand how it really affects you and your allowable bottom times ,(NDL – No Decompression Limits). Well why not reduce the amount of nitrogen we breathe?
Diving on Air (21% – Oxygen – O2 / 79% Nitrogen N2) to 18m, you can potentially stay for up to 56 minutes if you have enough air in your cylinders. Compare that to Enriched Air Nitrox x32 (EANx32) (32% O2 / 68% N2), where you can stay for up to 95 minutes and on 36% for up to 126 Minutes assuming you have enough gas volume with you.
Go a little deeper on air (21% O2) to 25m (say on the Canterbury or Waikato wrecks or anyone of the many sites at the Poor Knights Islands) and you can only stay for up to 28 mins. But on EANx32 (32% O2) you can stay for up to 40 minutes and on EANX36 (O2 36%) for up to 50 minutes.
Is it starting to make sense yet? Now add in the cost of a dive trip versus the time you spend underwater and the training will be well worth it.
So to dive on “Nitrox” you just need to complete the Enriched Air Nitrox course with us. This involves reading the SSI e-learning and then attending an evening of theory here in the classroom. We will plan some dives of different depths using different EANx mixes to decide which mix will be the best for that dive and practise analysing scuba cylinders containing EANx. .
If you’d like to then dive with Nitrox you are more than welcome to join as at the Poor Knights. Note the cost of these trips is not included in the course cost.
