Overview
The SDI Computer Nitrox Diver course was the first nitrox certification programme specifically designed around the use of modern dive computers.
Rather than relying on traditional dive tables, the programme teaches divers how to safely plan and conduct nitrox dives using a nitrox-compatible dive computer while understanding the benefits, limitations, and hazards associated with enriched air nitrox.
Training focuses on:
- oxygen exposure management,
- nitrox theory,
- gas analysis,
- dive-computer configuration,
- maximum operating depth calculations,
- and safe nitrox diving procedures.
At N9BO℠, Computer Nitrox Diver training provides one of the most valuable continuing-education certifications available to recreational divers, allowing longer no-decompression limits and shorter surface intervals when used appropriately.

FAQ
Enriched air nitrox is a breathing gas containing a higher percentage of oxygen and a lower percentage of nitrogen than standard air.
Nitrox can provide:
- longer no-decompression limits
- reduced nitrogen exposure
- shorter surface intervals
- increased flexibility for repetitive diving
when used within appropriate limits.
No.
The SDI Computer Nitrox Diver programme does not require open water training dives.
Yes.
Students learn how to:
- analyse oxygen content
- verify gas mixtures
- label cylinders correctly
- confirm dive-computer settings before diving
Many divers continue into:
- SDI Deep Diver
- SDI Advanced Adventure Diver
- SDI Solo Diver
- TDI Nitrox Diver
- advanced recreational and technical diving pathways
