Curious as to how the vx3 does in iron or nail infested relic sites also say in medium ground. Depth on a large copper or quarter in ground. I have seen some airtesting video and they aren't in English nor very good. I run and love my f75camo ltd with the 12x10sef. Wondering. How the vx3 compares I understand the VDI and tone I'd is better on the spectra but curious thank you HH c t
