Minelab Explorer S unexplained signals

[LeanSteveRI]

Working with my Minelab Explorer on a RI ocean beach today and had no salt water sand interference - good. However, I got several signals that were loud and high pitched from # 7- 26. Sometimes the ID icon would be displayed, sometimes just the ID value number. When I dug them either I couldn't find them or there was a small piece of metal. Any help on understanding this and should I ignore these signals?

Do they repeat in the same spot ? Versus momentary flutter that doesn't repeat ?
