PI Discrimination

[Deleted]

I copied this quote off of a website advertising the Garrett Infinium LS PI Metal detector:

"2. Discrimination (Target Elimination) – Fully Adjustable Discrimination Mode (This Control Doubles As A Frequency Control, See Below). Increasing This Control Increases The Amount Of Conductivity A Target Must Have To Produce A Signal."

My question is can the frequency control on a PI machine give any clue (ID) to what is being detected?

Thanks...

My understanding is it only discriminates between Ferrous and Non-Ferrous metals. And the Results are not all that good.

So I am Told.
