Would you like to spend longer underwater?

The PADI Enriched Air - Nitrox Specialty is for those wishing to extend their dive profile times, allowing you to see that little bit extra underwater.
On many dives, underwater time is governed by our no decompression limits. By increasing the oxygen and decreasing the nitrogen content of our breathing gas we can safely increase these limits. For example we can stay at 30 metres for twenty minutes on air. This can be safely increased to thirty five minutes with the correct enriched air mix so prolonging our enjoyment of the dive. At 18 metres using air you can stay for 56 minutes but this can be extended to 95 minutes. That’s a lot of quality reef time!

For the academic work we register you for the online Nitrox eLearning. You will need to read and complete the sections. Please make sure this is completed before your dives and you bring with you your e-record.
