I'm saying that the coal belt areas in Pa ARE heavily mineralized, and difficult to detect sometimes. unless he is in one of them.............his statement that the Pa mineralization is causing him problems is invalid. The soil in Pa is largely pretty nice, but there ARE exceptions........................
[/quote]****************************************************************But if he is useing a Minelab the mineralization is no problem. Minelabs are great in mineralization........

thats not "quite" true. While minelabs were designed to operate in hot Aussie soil, there are parts in the states where they generally suck. Central Va is one of them, were its heavy IRON mineralization. They do NO better than any other VLF machine. They are not much better in the coal belt either. The coke drives em nuts as its soooooooo prevalant. While minelabs DO do better in "certain" types of mineralization..... (like at the beach) ......they to not work well in ALL types of mineralization. In those scenarios...............I'd just as soon use my LTD in all metal as ANY minelab. (cept for the Minelab pulses)
In super hot soil I have two Ground Balancing pulses I use. They (ground balancing pulse induction machines)
are the pinacle of performance in iron laden soils...........and I dont see any othe type of machine overtaking them any time soon. (and that includes Most minelabs....sans the Minelab pulses).
We went thru this with Garrett too. Garrett told us there is no place in the US where the Infinium (Their current Groundbalancing PI machine) even NEEDED to be groundbalanced. problem was..................they had never experienced hot Va soil, but after they got a sample of it....they changed their tune. Point is....even the manufacturers are blissfully unaware sometimes.
Hot soil: Groundbalancing pulse machines.
Certain types of difficult soils: A few minelab offerings and true threshold based VLF's in all metal.
Good soil: pretty much everything else.............................. (but mostly F series Fishers)
