Hello everyone another good question I purchased my F70 with the F75 coil package and I been using the 11" DD coil for coin shooting and it does good but the target ID isn't the best but is good. My question is is the stock coil better for coin shooting? Does it ID better then the big 11" dd coil?? I do like the 11" DD coil but just curious is the 11" DD just good for low trash areas and open fields? any help would be greatly appreciated! Thanks
