Its been a while since I detected there but they have some rules on when/where you can detect. Once the beach is closed for the season I believe its open to detect but one of their rules is no detecting within 15' of the waters edge, I cant recall if its different for the beach. Also, the rules state that you cannot use anything larger than a standard screw driver to retrieve targets. Like I said its been a while since I detected there, I'd suggest calling or stopping by the park office to see what the rules are. Last time I talked to them they were very nice and the guy was really interested in the hobby.
