  Metal detector - Wikipedia, the free encyclopedia
Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel reinforcing bars in concrete and pipes and wires buried in walls and floors.
Larger portable metal detectors are used by archaeologists and treasure hunters to locate metallic items, such as jewelry, coins, bullets, and other various artifacts buried shallowly underground.
One example is utilizing the skilled use of the metal detector to examine wide areas such as battlefield sites where surface scatters of metal objects may be all that survives.

We have called this design a "metal detector" as it lets you know when anything of a ferrous or non-ferrous nature is placed in the field of the coil.
When we place a piece of metal in the magnetic field of the coil, some of the lines of flux pass through the metal and are converted to an electric current called an EDDY CURRENT in the metal.
Metal objects that are away from the centre of the field are ok as they will have no effect.

 Viking VK-40 Metal Detector
Viking detectors are not only sold to treasure hunters right across Europe, but also to water authorities, local councils and many other service industries.
The VK-40 is Viking's newest and most advanced metal detector ever produced (which is quite a feat, considering they have been making excellent metal detectors in the UK since the "early days" of the 1970s).
This is a great detector, which is at least as advanced as very many much more expensive models - and that is probably why Viking metal detectors continue to be widely seen in almost all the country's metal detector clubs.

First is the high kickback voltage of the transmitter coil, which temporally blinds the receiver coil from the amplifying metal target signals near the turn-off time of the transmitter coil.
The nulling signal is then used during normal operation of the metal detector by combining it with the instant receiver coil signal in a difference amplifier.
It may also be recalibrated upon discovery of a metal target to provide the most up to date nulling signal for the ground around the metal target.
