●
If the distance between the magnetometer and surface

in-
crease without the sensitivity changing, it is more difficult and
maybe even impossible to locate the object (Fig. 9).
●
The maximum area is narrower than with larger objects.
Note:
● You can use these effects to help you specifically locate small
or large objects.
●
Vary the sensitivity and the distance of the magnetometer from
the surface according to the size of the object you are search-
ing for.
