Dive obx , oh yes its worth it. Unless you dont like stepping back in time to see what mother nature has turned many and I mean many of ships into the "Graveyard of the Atlantic". If you are up in Hatteras you are only 7 miles from the gulf stream , not too much of a boat ride to dive in warm,rich,teaming with life water that has upwards of 100' vis on a good day. I would say yes , get those classes behind you so you wont be left onshore while everyone else gets too see the true OBX
If you can get on a charter that is visiting some out of the way wrecks, there is a good possibillity of finding artifacts
Reef life is very abundant, dont miss out
