Dewi Nusantara is equipped with Nitrox facilities. Nitrox fills of up to 32% are usually available to all certified Nitrox divers for an additional charge. Nitrox dive profiles must be planned and executed with a Nitrox-compatible computer. It would be best for you to set the planned PO2 level within the limits of your certifying agency. All Nitrox fills must be analysed by the diver using it and logged before every dive. Nitrox certifications are usually available onboard to all certified open-water divers for an additional charge. Please contact us at least four weeks before departure if you want to take a course and switch to Nitrox during your cruise.
