Best all metal program for DFX

[stasys]

Hello, I am expert in minelab explorer but I am absolutely dont understand DFX.. . Explorer I use allways without discrimination, Audio Long, Ferrous.
DFX is not mine but I hear allot good things about, I know DFX not deep like explorer but more sensitive to small items, this is what I need now- detector for small items.
My friend looks like a bit not in understanding it so my question what is most important settings in DFX and settings changes to real max deep and sensitive beast? Thanks Stasys

I have dug incredibly small iron targets at old homesteads with the DFX setting in all metal mode. At first its frustrating because you think you have a false signal and when you sort through the dirt you'll find a small needle or pellet.
