Next dive trip scheduled? Many dive resorts and boat operators are requiring a logged dive or an update in the last year. This will fill that requirement.
The SSI Enriched Air Nitrox program will teach you how to safely plan and dive with enriched air mixtures of up to 40% oxygen. Diving with enriched air can increase your no-decompression limits, increase your safety, and reduce the required length of your surface intervals when compared to air.
