While your stock coil is built for maximum ground coverage and raw depth in open fields, the RC18C 7-inch concentric coil is a specialized tool for surgical trash separation. Swapping to this smaller footprint allows you to navigate dense iron trash, pull-tabs, and foil without your signals masking adjacent targets. It makes the detector lighter, highly maneuverable around physical obstacles, and much sharper on shallow jewelry and coins hidden in high-traffic parks.
