10. Search method
The metal detector searches while being moved, i.e. it reacts to a metal object buried in the
ground only when the search coil is swung above it.
Searching for metal objects is actually moving the search coil above the ground surface.
While doing this, the search coil has to be held parallel towards the ground surface and at a
minimum distance above it. The more lifted the coil, the less deeply the search.
The search consists of a uniform and
slow swinging of the coil one side to
another, while the user holds the
metal detector’s handle and uses the
armrest for support.
Too fast or too slow moving of the coil
could result in shortening the search
depth, especially for deeply buried or
small objects.
The search coil path during the search
resembles a zigzag movement, which
is a result from the uniform and slow
swinging of the coil one side to
another while the user is moving
forward.
The swing’s breadth and the user’s
speed are chosen according to the
terrain, the sloping and the size of the
area to be searched.
During swinging the user should avoid
hitting the search coil in the available
objects on the terrain (stones, tree
roots and tree parts, uneven ground,
etc.)
The precise location of the detected object is determined by moving the search coil in two
perpendicular axes, while the user stands still or turns round for detecting the signal from
different sides.
