I have searched youtube for the advantages of HF coils in iron. I hunt for everything, relic, coin, and Jewelry in medium to low mineralized soils. Like most you, the limiting factor is the iron contamination and I know the HF coils works better for small items but have seen videos of the HF coils being used in high iron contamination. My question is what would be your choice in coils (9in or 9 1/2 elliptical) and what is the advantage of HF coils in the iron. I can only speculate.
Also, I have the 11 inch x35 and I would think the 9 inch X35 would be an option, but the HF would expand my frequency range.
