Use nitrox for the right reason—and know your limits.
Nitrox can extend no-decompression time on suitable profiles, but it does not make every dive longer, deeper or automatically safer. Certification teaches you to analyse the mix and plan within its oxygen limit.
More oxygen also means less nitrogen—and a new depth limit.
More no-decompression time
On suitable repetitive or mid-depth dives, reduced nitrogen exposure can give you more time before reaching a no-decompression limit.
Maximum operating depth
A richer oxygen mix becomes unsuitable beyond its calculated maximum operating depth. Nitrox is not a gas for simply going deeper.
Gas supply still matters
A larger no-decompression allowance does not change your breathing rate, cylinder size, conditions or safe ascent planning.
Analyse, label, set and respect.
Analyse the cylinder
Personally confirm the oxygen percentage rather than relying only on what was ordered.
Record the mix
Label and log the cylinder according to the procedure used by the operator.
Set your computer
Enter the actual oxygen percentage and the agreed oxygen exposure setting.
Respect the plan
Stay within the maximum operating depth and the broader limits of the dive.
A compact specialty with practical value.
The PADI Enriched Air Diver course focuses on the decisions that make nitrox useful and safe: understanding oxygen exposure, analysing cylinders, marking the mix and setting a dive computer.
Request the gas before you arrive at the boat.
Nitrox is not automatically prepared for every diver or every operator. If you want enriched air, send your certification, planned date and dive-trip preference in advance.
The most useful mix depends on the intended profile. Site plans can change with conditions, so the final mix and depth limit must still match the actual dive.
Nitrox without the myths.
Does nitrox let me dive deeper?
No. A higher oxygen percentage creates a shallower maximum operating depth than air for the same oxygen exposure limit.
Will every nitrox dive last longer?
No. Your gas supply, breathing rate, conditions, group and dive plan may end the dive before the no-decompression limit becomes relevant.
Does nitrox prevent decompression sickness?
No breathing gas removes diving risk. Nitrox can reduce nitrogen exposure when used correctly, but safe planning, ascent practice and personal health still matter.
Can I arrange nitrox on the morning of the dive?
Do not assume so. Ask in advance because availability, filling and cylinder preparation depend on the operator.
Send your certification and planned dive date.
I can help check whether nitrox is useful for the trip, whether it can be arranged and which current cost applies.
