[QUOTE="Wally69, post: 480232, member: 1916"] Oxidised iron can give a good signal (high 20s) at depth, particularly when passing under the edge of the coil, and dissapears once dug if the discriminator takes out the iron signals. If I am careful, I find they are usually jumpy signals and then I switch to all metal mode to confirm it is an iron target with a high tone halo effect and walk away ............ but it could be a small silver coin next to or under iron. Other false signal is small bits of aluminium can, I find they give a false target centre and dissapear when I dig the hole. They are usually found a couple of inches into the side of the hole, often where I have placed the extracted sand. Good technique with the pinpoint function from multiple directions usually indicates the true centre, but it also confirms the junk ID. [/QUOTE]
