Went to the sand dunes just south of Blackpool after some advice from a member on here about detecting the beach opposite the old Pontins (now demolished).
The tide was quite far out, but I was having no luck at all, not a single signal for the first 15 mins, but then I moved slightly inland and got a strong signal and this popped up:

Now I know it isn't gold or a hammered coin, but as my first bullet casing, exiting for me

and next to it two more casings, these could be from the rifle ranges on the piers at Blackpool and washed down the coast.

The only other interesting find were:

No idea what it is, seems to have some copper inside it, but a decorative pattern on the front that cuts off, the item has not been broken or cut at the bottom. Has two eyelets on the top, any ideas?
The bracket thing has a hole and an opposite hole with a screw thread. it is amazingly strong, not sure what material it is made of, but impossible to even flex it with bare hands.
