I want to stay longer- I still have plenty of air!
Do you ever wonder why your dive guide says that you have to ascend back to the boat when you still have 80 bar left in your tank but other others in your group continue diving for another 10 minutes! The reason for this is that if you are diving breathing air you have reached your no decompression limit and open water divers are not qualified for decompression diving. In contrast, others in your dive group are diving using Enriched Air Nitrox (EAN) and this allows them to extend their no decompression dive time.
This is one of the main reasons that the first speciality course that many open water divers take is the SSI Enriched Air Nitrox (EAN) course. The EAN course allows you to maximise your bottom time underwater and this is particularly important when diving deeper than 18 metres and when you plan to do more than one dive a day. EAN is air that is enriched with additional oxygen and this results in less nitrogen than in normal air and it is the high nitrogen content of normal air that reduces your allowable dive time.
Diving with Enriched Air Nitrox allows you to:
- Stay underwater longer
- Reduce the time of your required surface interval
- Feel less tired on your vacation.
- The Enriched Air theory course costs €100. The course can be completed in half a day and is open to any diver holding an Open Water certification.
