Instead of detecting the metal itself, (that as we know can only be detected at short distance),detecting this effect could be done farther away.

Yes,sure PD detects at long distance the anomaly caused by conductive metals.This distances are impossible for normal metal detector.
My experiences with PD everybody from this forum know very well. I realy dont know very well if PD can detect 1k gold 200m,but i´m sure 15m is possible. Also small gold or silver objects can be detected at distances like 1m to 5m or more. Depth can be near the surface or more deep.but i never found one single coin buried more than 50cm,and the hoard of silver coins was 80cm underground...
