why do deep nails give such a good coin signal?

help dealing with those falses that we encounter. It seems to me detectors that do better in iron will have falses to contend with, "no pain, no gain" .
Falses tend to go from the low end on the conductivity scale to the very high end but also can creep up just a notch or 2 into the foil range, like with the Xterra into 2 or 4 readings.
Most of these falses are momentary and can be discerned quickly and dismissed but sometimes ground conditions, like moisture content can add or subtract to how many falses occur.
Smaller coils help in the trashier spots under these conditions.

I get fooled more often using 2 tones then when using 4 or 99 tones.

Digger;

It seems to me that if you use the PINPOINT mode to accurately locate the target and then switch back to the C/T mode, the X70 more accurately identifies the target as iron. As you move away from the exact location, then you tend to get more false high conduction tones. This has been my experience.
