What Is A Metal Detector by Keith George
As the name suggests a Metal
Detector is a kind of instrument, which is used to detect metal with the help of
electromagnetic induction. It helps in the detection of land mines, weapons like
knives or guns at airports, in treasure hunting or in archeology. It can also be
helpful in detecting foreign bodies in food.
Construction industries find it useful in detecting steel reinforcing bars
present in concretes, pipes, or wires in walls and floors. It can sense any
electrically conductive piece of metal. Metal detectors came into being around
the end of the 19th century.
Metal detectors have many applications. In archeology metal detectors are of
good help. But in some countries like France and Sweden law prohibits metal
detectors, but with special permission it can be used. In spite of all these
restrictions the contribution of metal detectors in this area cannot be denied.
A good example is the utilization of these detectors to inspect wide areas like
sites of battlefields, where the only remains could be the surface, scattered
with metal objects.
Some times people use consumer metal detectors to find coins on the beach as
their hobby. Generally in the following types of hobbyist activities metal
detectors are used.
Coin Shooting, searching for coins, mainly old coins. Prospecting, searching for
precious metals like gold or silver Relic Hunting, searching for any thing that
has any historical significance, like weapons. Treasure Hunting, searching for
hidden items.
For security purpose metal detector are of great help. In airports this is used
in great extent as it helps to detect any dangerous items carried by passengers
that can cause harm to others, especially weapons,
One should know the right procedure of using a metal detector. Here are certain
vital steps for using a metal detector:
The very first thing, that is needed to take care of is tuning. This means the
detector must be adjusted so that it can recognize the ground as a channel for
the targets to be inside. Sometimes however the devise posses a self tuning
trait installed. After this one is ready to go for the search of the targets,
coins, treasure or anything. The placement of the loop is also very important.
To get the best functioning it should be held at arms length along with the loop
and it should be barely above the ground and the loop must always be in motion
for best result. While searching with the detector one should move at a slow
pace.
