Any other NC gear tips?
NC diving is all open ocean diving. Be sure to have gear that can get you rescued if you get separated from the boat on the surface. SMB, whistle or horn, light. The reel can be used to deploy your SMB from 15 feet should you get lost and have to make an ascent away from the anchor line (which is a BIG no-no). Then the boat will know where you are (and what direction you are drifting) while you do your stop. The boat cannot come get you until all the other divers are on the boat, and the anchor is freed from the wreck.
