COMMUNICATION: it is with great regret that in 2021 we are forced to suspend technical diving activities mainly due to the ordinances issued in recent years by the Olbia Harbor Master’s Office which prohibit all the main historical wrecks of the Gallura sea from technical diving. We are working together with the Italian Navy for the reopening of the wrecks currently under ordinance.
Technical courses provide the techniques and procedures necessary for diving beyond recreational dive limits. These are some of themost intensive, yet exhilarating, courses you’ll find.
Technical diving isn’t for everyone but if this type of diving appeals to you and you’re willing to accept the risks, responsibilities and obligations, you’ll find it one of the most rewarding dive experiences you’ll ever have.
