Hi guys. I am new to the Racer 2, Back and tell what has a lot of potential in areas I struggle with using my Etrac. I am in the area now my Etrac nulls in even with my 6 inch coil.I have the Shrew and 7" concentric coil along with the stock coil. I would love to know what settings you guys have worked with for pulling both shallow and deep all the coins out of heavy iron locations. Thanks in advance
