Due to the design characteristics of an X-TERRA Concentric coil, (think

of a circle within a circle with the outer coil being the transmit winding

and the inner coil being the receive winding), the detection eld near

the surface is much broader than the Double-D coil. However, as the

detection eld of a Concentric coil penetrates the earth, it narrows from

all directions. Because of this, I try to overlap my sweeps by at least a half

when using a Concentric coil.
