wire mesh or rebar in the concrete. This allows the operator to not only pinpoint the location of
the cover but to also outline the tank and determine precisely its orientation.
Figure 9: Manhole Cover
A typical manhole cover is actually a combination of two magnetic fields: the magnetic field of
the cover itself and the magnetic field of the steel support ring. When both fields are aligned,
they add and are easy to detect. When the manhole cover and its support ring are 180° out of
alignment, their magnetic fields tend to cancel and the detection distance is greatly reduced.
