Corolla OBX. Was doing towel line and found usual junk. Set AT Pro for recommended “best you can do” wet saltwater beach. Hit 15 yards or so from surf at low tide, 8 inches deap with ID 58 . Wow....now I’ve been reading up all vacation and thinking I need a deticated beach detector. I’d get a used detector and hope for under $500.....I’m once a year beach but will retire close to the shore From ring markings, it’s 14k white gold band.
