Part of missing target audio response can be due to a fairly fast
sweep. But I am able to maintain a fairly quick sweep speed in All
Metal (zero-discrimination), multiple tone, and remain condent I am
hearing everything under the coil. When the Threshold blanks out in a
Discrimination Pattern, I don’t have any idea how many rejected targets
I’m passing over. That is because the Threshold is replaced by silence
while those rejected targets are still within detection range. In All Metal,
multiple tone, the Threshold goes away. But instead of silence on rejected
targets, I hear a tone for everything. Again, this is another one of those
“personal preference” settings. Back to the coils...
9-Inch 3 kHz Concentric Coil
As I said, I like the 9-Inch 3 kHz Concentric coil. Not only because it is
theoretically better with higher conductive silver and copper. But being
better suited for higher conductive targets results in it being not as well
suited for lower conductive targets (like deep iron).
