Common Magnetic Signatures

Most common underground targets have a predictable magnetic pattern and consequently

produce a predictable output frequency change in the magnetic locator. In the figures that

follow, the bold line above ground indicates the relative output frequency level of the

DML2000-XR as it moves across the indicated target; the higher the line, the higher the

instrument output frequency.

Figure 4: Survey Marker / Well Casting

The peaking of the DML2000-XR output frequency normally indicates that you are over the top

center of a vertical dipole (survey marker or well casing).

Figure 5: Chain-Link or "Cyclone" Fences

Hold the instrument vertical to the ground, and walk parallel to the fence (approximately 8" to 1'

away). You will hear the magnetic field of the fence and fence posts as you walk. If your target
