The metal detectors in airports, office buildings and prisons for example help ensure that no one is bringing a weapon onto the property. Consumer oriented metal detectors provide entertainment to people and give chance in discovering hidden treasures. How much will you spend on a detector? It is advisable to be a little flexible in this regard so that one can buy one that most suits the requirements.
Metal Detector Parts
If you are one of those people who wonder about those weird people with sticks that make noises, think no more. What they are holding are called metal detectors and they are not only used by treasure hunters but also for security purposes like bomb or firearm detection. These contraptions are very useful. They can give signals even from the smallest coin deep sited. How can it detect those metals? Here is a 101 on the parts of a detector and how it works. You need to know the parts of it and its operation to understand what this contraption is telling you when you hear those weird beeps.
Metal detectors for hobbyists or those who just try metal detecting for fun; has equipment that is simple and lightweight, unlike those for security purposes. This simple contraption is composed of uncomplicated parts.
1. Control panel or box - literally the area of the detector where you control almost everything. Inside are the circuits, batteries, the processor and the speakers.
2. Tube - more commonly known as the shaft. It attaches the control panel and the search head.
3. Search head - most important part of the detector. It is the part that spots possible treasures around. (It has other names also: loop, antenna, or the search coil)
Metal detectors work on the principal of electromagnetics and their effects on conductive metals. There are actually two separate elements in the coil of a typical unit. One is a high-powered coil of metal which uses the battery power to generate a penetrating magnetic field. Youve got to buy a metal detector that could withstand normal wear and tear longer than its competitors. The longer the metal detector can serve you, the better your return on investment will be.
My recommendation is to simply allow mining companies to clean up this contamination in the California watershed through large dredging and sluicing operations without risk of civil or criminal liability, and possibly for a profit. We must also allow recreational miners greater access with fewer restrictions in the smaller creeks and streams that would be inaccessible to mining companies.
Any place there is construction and the ground is being cleared, that is a great place to start treasure hunting. Successfull treasure hunting starts with having the right metal detector. But which type of metal detector should you get? Complete info on metal detectors and treasure hunting at http://detect-metal.info. The good news is that prices have never been lower for such easy to use full featured automatic detectors. A good way to view the purchase is to decide how much money you are comfortable spending.
Some metal detectors use BFO (Beat Frequent Oscillation). This technology contains two coils of wire. The two coils are represented by two wires which is the large and the small. The large coil can be found in the search coil of the detector while the small coil is found on the System Control Pack.
4. Stabilizer - it aids in your control when you hold the item. This is now common for most metal detectors but not all detectors have this feature.
5. Headphones - this part is also optional but advisable. It aids you in listening only to specific noises. You can hear even the slightest sound of beeping. You can also reduce the sound around you by adding this to your machine.
There are three types of metal detectors these are: VLF, PI and BFO. VLF or Very low frequency is the most commonly bought detector on the market. This type of machine generates an electromagnetic field and can detect at what level or depth the metal may be.
PI or Pulse induction is not as common as the VLF. This contraption generates and uses the coil (just one) as the recipient and spreader of the impulses. The good thing about this item is that it can locate deep sited metals and in areas that other metal detector types have difficulty in.
BFO or beat frequency oscillator is the most common and down to earth contraption there is. This type needs 2 coils that are linked and generates radio-waves. These are the cheapest available that are being sold in stores. Remember when you know how a detector works you will enjoy doing it effortlessly. Research more and get that detector. You never know what you just might get.
When hand-held detectors are switched on, a red signal pattern in transmitted from the coil to the ground. When the signal comes in contact with a metal, it interrupts the signal and the detector alerts the user with an audio signal and flashing lights. So next time you loose that ring at the beach or you dime at the park remember there are ways to find you beloved object. Have Fun. Find the best gold metal detector today and start treasure hunting!
Remember, the higher the coil is above the surface the more depth you will lose. If they've got a old coin that is 6 in. below the surface, and your detector can detect 8 in., and the coil is 3 in. above the ground, you will miss that target. If the coil had been directly upon the ground you would be able to detect that target. The Garrett Enforcer G-2 is the smallest body scanner and sensitive enough to detect even the smallest of knives or guns. The most popular one is the Super Scanner. It can detect hatpins as small as one inch.
