Very nicely run dive shop. Often Nitrox is free (I mean there’s no difference between air and nitrox fill) but you just go with whatever mix they have (usually between 30-32). All you need is to show them your speciality card. The crew from ProDive is very friendly and very well organized. At the end of your stay you’ll get the "ticket" with all your dives listed with whom (DM) you did it and which dive site you dove. They have 4 dives a day and Monday and/or Wednesday night dive if there is interest in it. So in a week you can see most of south-western dive sites (most people say the best part of the Coz). Actually I have to tell Hans (he runs this place) maybe to drop in on DB, so I don’t have to advertise for him :)
