Whenever the search for
a specific object turns out to be difficult
(maybe if said object is small, relative
to the size of the search area), a geophysical
check-up makes a lot of sense – sometimes
it proves to be the only sensible option.
The choice of the most appropriate technique
depends on the properties of the location
and the type of object in question. Using
the methods like magnetics or ground penetrating
radar, almost any kind of object, void or
inhomogeneity can be found, whether they
are below the surface, in water or in the
walls or ceilings of buildings.
