To find the best metal detector, hop right over to ebay. It does not matter who the manufacturer is, as long as the user knows how to effectively utilize the equipment at hand. Some people have used metal detectors to uncover items of great value.
The success rate of metal detectors has a lot of variables. First, the metal detectors themselves have different degrees of accuracy and sensitivity. Some are quite sensitive, and others are less so. Secondly, the treasure hunters need luck, skill and good information about where metal might be hidden. All of these factors play into the success of a treasure hunt.
In general, most metal detectors have the capability to detect both iron and aluminum since they both conduct electricity. However, adjusting the sensitivity settings on some metal detectors may allow you to differentiate between the two types of metals to some extent. Specialized metal detectors for industrial purposes may offer more specific discrimination between different metals.
I believe it is important to have metal detectors in our government buildings and schools. We have had shootings and people killed in the court rooms as well as many schools. At least this will help some. It seems that some people seem to get in no matter what we do. Just like the shoe bomber on the airplane. It certainly is important to have the metal detectors at our airports. At least society is trying to prevent tragedies from happening.
If you are talking about metal detector that you buy as a hobby for finding things then yes of course it will. But security metal detectors are adjusted so they aren't usually set off by something like earrings or a ring if that is what you mean. Though if you have a lump of silver in your pocket I imagine you would set off any metal detector. There are many instances of metal detectors detecting silver. Some of the largest treasure finds in the UK were hordes of silver coins found by people using metal detectors.
Metal detectors detect mainly metals. You can dial in some really specialized detectors to get non-ferrous metals - like gold. I have never heard of glass itself distrubing gauss lines in magnetism - therefore you cannot find pure glass with a metal detector. The lids and bottle caps are metallic and those you might be able to find.
no, because aluminum foil is not a metal, it is an alloy.
Americium is a metal. It is a synthetic element that belongs to the actinide series, which is a group of metallic elements. Americium is used in smoke detectors and some types of industrial gauges.
Metal detectors can be tuned in order to avoid the beeps on small metal objects. It does however depend on the detector in use, and the securitylevel it is set for. It also depends on the size of your braces. Some have more metal in them than others. Some have braces only for a few teeth, where as others have a full "railroad". The full railroad is more likely to produce a beep, but you can still travel. There is no problem with bracers and travelling by plane.
Click on the link below for the answer. Common metal detectors work by sending out a radiofrequency energy signal. This frequency will change slightly when the 'antenna' is in close proximity of various metals. Many metals will absorb this energy. The detector notices this absorption and can these days indicate what metal it is and even the distance to the metal. Some metals also reflect this energy signal and when a reflection is picked up, this can also be used to indicate type and size of metal object. High tech detectors use a combination of many methods of which increases its accuracy drastically.
Hire more school security, use metal detectors, have a zero tolerance policy for fighting.
Advanced metal detectors can check for the difference between coins and gold nuggets. You can look for other precious metals or gold rings.
