Locating and Tracing Barbed Wire
You can often trace barbed wire (from old fence lines)
buried just beneath the surface. Even if the wire is only a
trail of rust, it can still be detected near the surface. Tip
the locator a little lower than usual - but not parallel with
the ground.
Figure 20: Tracing Barbed Wire
Examine trees for bench marks and bits of embedded
barbed wire. Hold the locator parallel with the direction
of the wire.
