How to detect (open to friendly speculations) minute magnetic field changes
?
In application such as;
* Detecting a crashed small aircraft in a very dense forest from another
small aircraft fliying at a hight of 1000-4000 feet AGL.
* Detecting metal pipe 10-20m below in ground.
* Detecting a small metal boat sinked to depth of 00-200m from the
surface of the sea.
* Detecting earth magnetic field variations from a low orbit atellite or
from a high altitude flying baloon.
