Interesting. When i notch out iron i still get a low tone but usually don,t lock on to an i.d. beyond iron. Some iron i need to swing coil off till icon clears.
A bent,(suggesting a round shape)nail or a nail standing on end with head on top,especially one rusted creating a halo on occasion rings as coin. By swinging coil over it from different directions usually gives varied or iffy i.d..
Usually run in jewelry mode and iron not such a distraction. When swinging, iron just a low tone when passed over. Keep swinging. Mid tone i,ll check i.d. or dig. tabs need digging to not miss gold. I get digging tone more than i.d. after awhile. Where a silver rings up or older copper will i.d. just a bit lower than clad and zink. See if you find a sweeter tone when you hit a silver dime. Its out there waiting for you. H.H.
High tone same with more excitement if coin shooting.
