My new ID Excel arrived this morning. I already tested it and found that my weddingband is easily located when wrapped around a rusty roman nail. I have found that this only applies for higher conductive targets, because I also tested this on a small pewter badge, which sounded nice and crisp (and deep) until I put the nail right next to it. I will put the excel through a tough test tomorrow, when I am hunting the (extremely heavily hunted) site where there once was a Celtic temple. So.... maybe I'll have some Roman/ Celtic stuff to show you tomorrow!
