Phil,
Yes, there is an upgrade for the Surfmaster PI
to make it more sensitive to small gold! Visit
"www.surfscanner.com" at "Detector Modifications".
Mr.Bill explains what he does and guarantees the
results. I just sent my PI detector to him for him
to do this since my PI would not pick up a gold
chain even if I rubbed it on the coil! Read about
it and I am sure you will be very excited. It only
costs $70 plus your postage both ways. As for any
iron discrimination on a pulse detector, it does
not exist or function like you expect with a VLF
and the upgrade is only to increase sensitivity.
