Those 2 targets the screw and coin together are seen as one this is a blended target with iron and silver copper or other high conductor . If the coin and screw are not touching then you would get audio .
Disc well not effect the target because it's seeing iron and a high conductor at the same time and you can not disc out the high conductor . But iron by itself will disc out .
I still don't know why the signal dose not give audio I think it's canceling out the audio part because the signals are canceling out each other ? .
If you run in pattern 1 the same thing happens no matter what level of disc you use even with the screw disc out .
I think the target trace is more intelligent than the audio because it can place the two on the screen at the same time .Maybe the audio dose not work because it can't tell what it is a high conductor or low conductor .
But if you put a pull-tab with a dime it well read 12.35 instead of 12.43 low conductor with high conductor touching why it gives audio in this situation don't know all I can say is it must be a iron thing
