For your/our home waters you’ll need the drysuit, navigation because we can’t see the anchor line 15’ away. Deep if you are going offshore NJ and EAN if you want to stay awhile. Rescue is always good and I hope you never need to use it. I took an equipment class because most shops in my travels didn’t know how to open an Oceanic Omega reg. The class size was small so we used my daughters and my equipment so the class cost vs getting the equipment serviced was a wash :)
