Good one Lab. The DD tends to narrow on both ends toward the center the deeper it locates a target. It doesnt graduate as quickly as the concentric but its much like someone stepping on a funnel.

The coil emits eddy currents as in the animation,but it bounces off any metal present,learn to go by the sounds,
presuming you have the detector set for the most sounds,listen for the silver tone,ignore the other,if it peeps,or is iffy with a silver
chirp,or signal,dig, this is a good indication of silver masked by another object,even iron,with nulling present.

You know Harold im not sure that picture of the eddy is corrrect. I might be out to lunch, but normally the outside coil sends the eddy and the center coil is the receiving coil. Thats why when you are in pinpoint the receiver or center coil is activated. Hey, anyone chime in here. It might be different than it was with other detectors i have used.
