Croatia is good Diving and Tony is a good instructor. Did my mod1 with him. If your interested I expect the dive centre would be shark Diving , medulin. Nice bunch of people , good facilities and a bunch of wrecks , many 35-50 mtrs. Try to do the one that’s split in two and joined up by a bit of smb line. The Rosorol is good , the stern is better. That’s in two bits but not doable on one dive unless you’ve a scooter and know where to go. Baron gauch is excellent and you can do the whole wreck stern to bow inside. Edit - looks like the smb line wreck is the Argo, 47 mtrs.
