I'm hoping with all these different tweak options, including an actual manually controlled ground balance that I can squeeze a couple more keepers out of some very worked sites. Most are in corn fields. I have used my Explorer SE's with the largest coils made for them, so I am assuming most of the finds I'll make with the DFX are going to be in areas with dense iron, I hoping the DFX is faster and better at picking through the trash. Has anyone had any luck with the Big Foot coil??? I'd like to get one of those to use as a scouting coil in the corn stubble.
