With all the new F series detectors from Fisher, I'm wondering if any have a mode comparable to the JE mode on the F-75? It always amazes me how the F-75 will detect super small items. Sometimes it takes hard looking with the FX-1 probe to locate the target in the dirt pile and turns out to be something the size of a metal filing. Micro-jewelery can't hide from the F-75.
