I've just been told that I am going camping this weekend in Swansea with my partner and her sister

However, after a heated discussion she has agreed that I could take my detector so that they can visit stately homes and girl stuff like that
I'm just wondering if any of you out there have visited this part of the world and any advice would be very much appreciated, I have a Etrac and have never yet used it on the beach.
Cheers all
