Nitrox Nitrox is available in our dive-operation if reserved 24 hours prior to the dive. We usually use 28-32 % oxygen in our mix, which keeps us safe in greater depths down to 40 meters. Our nitrox provider is a annually checked and certified filling station in the old harbor and these are very reliable guys. Good pressure and clean nitrox! Nitrox courses are available all year round, so don´t hesitate to book.
