Get longer bottom times on Hikkaduwa's reefs and wrecks with the SSI Enriched Air Nitrox specialty. Learning to dive with higher-oxygen blends extends your no-decompression limits on the multi-dive days that suit Sri Lanka's south-coast sites. It is a knowledge-based course you can complete in a day, with optional dives to put your skills into practice.
The SSI Enriched Air Nitrox specialty can be completed as digital theory with gas analysis, and counts toward the SSI Specialty Diver and Master Diver recognitions. SSI certifies enriched-air use up to 40 percent oxygen at the recreational level.
Nitrox is most rewarding on Hikkaduwa's multi-dive reef and wreck days, where extended no-decompression limits maximise your time underwater during the calm November-to-April season.
