Lost handmade wooden Cajon drum with dark finish and distinctive scratches near the beach picnic spot in Hilton Head.

I lost my beloved Cajon drum while I was spending a relaxing afternoon at the beach in Hilton Head. I left it near our picnic spot around 4 PM, but when I returned, it was gone. It's a wooden, handmade drum with a dark finish, and it has some distinct scratches from use. I would really love to get it back as it's very special to me.
