Have you ever been on a dive where you had the gas supply to carry on but you were restricted by the no-decompression limits of your computer or tables but you were itching to keep exploring?

The SDI Computer Nitrox is the course you need to extend your bottom time in the recreational limits and get the most out of your gas supply on dives. The course covers safe use of Nitrox mixtures between 22-40% oxygen, how to correctly analyse your cylinder contents and ensuring you can program your dive computer to get those lovely longer dives with the interesting stuff!
