The 10x5 packs a punch. Very strong mid size coil. It hammers small objects. I dug smaller rivets yesterday that I don't think I would find with the standard coil. This is a good and bad thing as I think the coil suffers a loss of depth in iron because it picks up on the smallest pieces of debris. This is a catch 22. It might separate better on surface finds in heavy iron. I pulled an 1851 seated dime out of a heavy iron site yesterday and I know the site had been searched by multiple detectorists that all use Equinoxes. Plus the site was searched multiple times with a Deus. Good day though with 2 silvers and a V nickel.
