Enriched Air (Nitrox) Specialty
Would you like to spend longer 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 meters 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. To enroll in an enriched air course you must be over 15 years of age, be certified as an PADI Open Water Diver (or equivalent) and fill in and sign a medical statement.
