We had wonderful dives with SUBEX. First of all, they take safety very seriously. The first dive is called welcome dive and they will check if you still know the basic drill. Afterwards, they will give you really helpful tips how you could improve. The boats are comfortable and we were lucky enough to have only a small group on the boat. Therefore, we had plenty of space for getting geared up and for the nap between the dives. Staff is very friendly and helpful. Can be highly recommended!
