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.
