My hunting partner Satarro and I just got the small coils for our machines. I got the 6 inch for the nox and he got the 5 inch for the cruiser.Last weekend we spent three hours in a hunted out site and he found the only coin a memorial. We went to this site today armed with the small coils and reopened the site for now and future hunting. I got a trifecta on nickels, 1v,1buffalo,and a Jefferson along with three wheats. He got a wheat, a Jefferson, and a cool enameled Mobil Oil Company lapel pin in good shape.Also note Mobil oil company was founded in our home town about 1 mile from this site.I loved the 6 inch coil and feel most of our old sites will now be reopened since they are so trashy. We found all these targets in an hour or so then got rained out. The water wasn't the issue but lighting did send us home.
