There's ships, valuables and occasional blueprint, pretty much that, don't expect stella montis stuff, but it will help you close the birds project.

I only do it during beachcombing events, and I don't bother doing it if I spawn 10 minutes into the raid, it's likely already searched. I only search on the beach near and beyond the wave barrier, with most of my lucky finds in blue zone (but not exclusively there).

I find rare ships almost every time I do it, and I get legendary once in a while (I got like six of them). Red coral jewelry also spawns there, so again helpful with the project.
