Old and rare toys and games are a particular collector's favorite, as are newer ones that are connected with popular films and TV series. The latter need to be in really good condition. 20 years ago, as a kid in his mid-teens, my cousin was buying Star Wars figures and keeping them sealed in their [...]
A pulsing current is applied to the coil, which then induces a magnetic field shown in blue. When the magnetic field of the coil moves across metal, such as the coin in this illustration, the field induces electric currents (called eddy currents) in the coin. The eddy currents induce their own magnetic field, shown in [...]

In general, larger searchcoils will give better depth with larger targets and better ground coverage. However, sensitivity to smaller objects may be sacrificed. Smaller searchcoils will offer greater sensitivity to smaller objects and improved target separation in trashy soil. As you can probably tell metal detectors are very useful not only to find that cherished [...]
A metal detector should not be bought solely on the suggestion of one person (no matter how good a friend). If you are new to the hobby, you should realize that long time detector users can be very committed to the particular model and brand of detector that they have been using. They are generally [...]
