Key Things You Need To Know About Metal Detecting - Hobbies

Metal detecting is a fascinating hobby. There arent many like it that can just give you such a top notch thrill. However, way too many people go into this hobby, without arming themselves with knowledge, and end up doing a vast number of things wrong. In this article, Im going to touch on just a few things that I think you must know before you venture into the land of coin collecting, relic research and hunting for treasure.

One thing that a lot of beginning metal detecting fanatics dont think about is the law. Yes, there are a number of laws governing the activity of metal detecting, such as where you can actually carry this activity out. For example, in many, if not all states, you cannot go hunting for metal in grave yards. Naturally, youll want to check with your local laws, but Id keep away from cemeteries. Most metal detecting forums wont even allow you to discuss metal detecting in cemeteries.

You need to have a method to identify your finds. Naturally, this is going to depend on what it is youve found. For example, lets for argument sake say youve gone out searching for coins and youve found something that looks like an old 1937 penny and you want to know how much its worth in the condition that youve found it. In that case, youre either going to need to get yourself a coin collecting book or take it to an expert. Yes, metal detecting goes off into other areas as well that you might not be so well versed in. Be prepared for this.

Finally, and this is another thing beginners dont think about, there is cleaning your finds. I mean for crying out loud, youre not going to leave the darn thing in the condition that you found it, are you? Well, every metal needs to be cleaned differently. Youre not going to clean that 1937 penny the same way youd clean a piece of gold. At least I hope not. So, you guessed it, youre going to need several books on cleaning metals unless you can find one that covers it allfrom pennies to whatever.

Yes, metal detecting can be a lot of fun. It can also be a lot of work after the fact as well. There are rules and regulations, mostly government made, that you have to be aware of and you certainly need to know what to do with your find after youve found it.

New market opportunities driven metal detector industry booming - the market, metal detector gate - - News - Business News

Born from the metal detector gate to the present, its Technology Innovations, applications, great changes have taken place. "The Gate" and the detection technology combining the enormous effect of the value of reserves, has a deeper prospects. This paper is focused on the metal detector gate Market Status, product technology development profile for the industry reference.

Security metal detector known as the door is a metal cutting through the magnetic field line to make sense of volume change, and then through the CPU Host Processing system to handle this change into the alarm sound and light products.

Metal detector mainly consists of the following components: gate main structure, Probe, Infrared control, main control circuit, display circuit and power supplies. Foreign brands, with Finland METOR (Maiteruike), Italy CEIA (Kia) and the United States, Garrett and so on. Its working principle is to pass the signal acquisition card analog signal, after analog processing of signal amplification, through the A / D conversion, converted by DSP filtering, and finally processed by digital logic circuits.

About the early 80s of last century, metal detector gate appeared in China. All along, the international brands occupy a pioneer metal detector market position. In 1992, Guilin Pan-Asian Electronic Co., Ltd. China independently developed the first security door. Subsequently, the country has emerged more powerful group of manufacturers, such as Xinyuan Tong, Tian Tong so.

Broad market demand Metal detector gate at first limited to airports, important juncture in the field use, and then extended to prisons, courts, government and other important departments, and various gatherings such as sports, galleries and other places. 90 China's rapid economic growth, trade and economic activities have become increasingly developed, the general Enterprise, Places of entertainment have gradually been used increasingly by professional metal detector market spread to the civilian market. In recent years, metal detector gate has also been a growing number of manufacturing enterprises (such as gold and silver jewelry factory, the electronics industry products factory, metal fabrication, Mint, etc.) of all ages to use Security. There are also entrance, driver's license examination room and so on, install the metal detector to prevent candidates to carry cell phones, MP3 / 4 and other tools for cheating. Therefore, Guilin Pan Electronics Co., Ltd. Sell Shi W ei, director of application of the metal detector gate summarized into three areas: security testing, security, anti-cheat. With the metal detector gate

the progressive development of more and more have begun using metal detector gates, as some important research institutes or laboratories, in order to prevent copies of relevant staff important information away U-disk or hard drive; in some special occasions, such as important bidding site, conferences, forums, etc. Those joining in carrying prohibited to prevent recording, camera equipment. Some industry insiders also believe that the metal detector can be applied to banks, Internet cafes and other areas to prevent access to those who carry knives, guns and other goods caused by accidents. But so far, metal detector gates at the bank, the application of the field of small cafes, and only a small amount of application powerhouse bank vaults. With the emphasis on government-related issues, introduction of the State Council issued a similar 2006,2008, "Entertainment Management Ordinance" to regulate the safety management of Internet cafes is not possible, then the door will also broaden the application of metal detectors. Interview also learned that some of the Chinese manufacturers are trying to match foreign brands, hoping to upgrade the technological content of their products to enter the airport area.

Rational face of the chaotic market situationIt is because of the metal detector gate to expand the scope of application, current market conditions there are some new changes, on the one hand, many non-professionals users, their general principles of equipment, use techniques are poorly understood; other On the one hand, some manufacturers to highlight the advantages of their products, product performance information in there on "speculation" phenomenon, which makes the current market seems to be rather confusing and complicated, the urgent need for the application of the guidelines and education markets.

Users lack of knowledge on product marketUser principle structure on the metal detector do not understand the errors caused by product purchase. To location, for example, in general, metal detector in accordance with its height is divided into six zones, from bottom to top were 1,2,3,4,5,6 area. 1 to 6 area location for the sensitivity, the sensitivity of each area the size can be adjusted. Conditioning in the overall sensitivity, but also to achieve the overall sensitivity adjustment, which is called the seventh district. An industry that aims to establish the location of the various metal objects can be distributed, multi-location may also alarm and accurately determine the location of metal objects. Manufacturers advertised their products too much more than location, may mislead the purchase. Another example of digital technology, a professional who says: "All digital metal detecting gate is to be able to analyze the signal characteristics of all metals, for intelligen t, automated processing, and manifested through the product." Metal detector gate current analog circuits do not with intelligent signal processing, digital circuits can only identify a subset of metal properties, the so-called "all-digital metal detector gate," in fact only part of the digital implementation.

In addition, metal detector is also required in the installation expertise, so if the user in the installation and testing products, technical control is not in place, they are also likely to affect the performance of products to play. According to market feedback that the present number of targets can not be detected correctly the situation, the operator may adjust the sensitivity caused by random omission, it may be too strong around the source of interference caused by false positives. Therefore, installation and commissioning process should pay attention: according to the actual needs of applications to set the sensitivity, detection sensitivity is set too easily lead to false positive rate increased, appeared too low and easily omitted; metal detector around 1 to 3 meters should not be large pieces of metal objects or movements exist, the installation location should be away from the wire, communications cable, wireless radio remote controls, power tools and other in terference sources, in order to avoid outside interference; multiple metal detector gates used at the same time, it is best to keep a certain distance and Set different frequencies to avoid mutual interference effect detection accuracy and stability.

METAL DETECTING - A FANTASTIC HOBBY - Hobbies

Over the years I have been involved in many hobbies including stamp collecting, coin collecting, radio controlled airplanes, flying and you name it. Of all those hobbies the only one that ever made any money was metal detecting. Not at first but as I learned more about it and acquired more sophisticated detectors it became more and more profitable. However making a profit was just a sideline. There are many more advantages to metal detecting. For one thing it is a great form of mild exercise and you are outside breathing fresh air. Also you learn a lot about history.

When I first got interested in metal detecting, I bought a cheap "build it yourself" kit from Radio Shack. It was midnight when I finally got it all assembled. I went out to the front yard and turned it on. Right a way a got a beep and dug up a scrap piece of tin. That was it. I now had the bug. I next visited a local treasure shop and looked over the commercial metal detectors. At that time the Compass brand was very popular. I bought the low end model. Big mistake. I very shortly realized the limitations it had. Back to the treasure shop. I traded in my low end model for a more sophisticated one. That's when I started making some interesting finds.

Living in California was a great advantage to metal detecting. Not only could I hunt old ghost towns and mining camps but there were also many beaches to hunt. Beach hunting is fun. All you need is your detector and a sand scoop. The possibilities are endless. I have found jewelry, coins, keys, knives, silverware and fishing equipment.

Hunting ghost towns and mining camps is a whole different ballgame. A little more equipment is necessary. You need various digging tools depending on the area. A really strong digging knife is mandatory. Sometimes a small pick axe is helpful. Finds run the gamut from old coins to all sorts of items from the gold rush days including military belt buckles, military buttons, gun parts, Chinese coins and opium tins.

Over the years metal detectors have become more and more sophisticated. The high end models will tell you what the target probably is and approximately how deep. They will also rule out many of the junk targets that plague metal detecting.

If you are just starting out in the great hobby of metal detecting your best source of information is obtained by joining a metal detecting or treasure hunting club. Also your local metal detecting dealer can be of great help.

Metal Detectors Explained -

Metal detectors are devices specially designed to detect metals that lie deep in the water or ground. When it was invented, it is specifically designed for screening or security purposes and to locate mines. There is a lot of industry which uses metal detectors such as food processing, textiles, pharmaceuticals, chemicals, packaging and plastic industries. It is important to check the foods for metal debris to avoid food poisoning. Those metals debris can be broken down to pieces on the machinery in food processing industry. On the other hand, you may find a lot of people that use metal detectors in hunting for treasures and old coins that are electronically driven. So, you might wonder how this thing work to detect metals that are hidden or how metal detector that is hand held work. So let's take a closer look at these detectors to know how they work.

Metal Detectors: How Do They Work?

Generally, metal detectors work on the fundamental principle that when electric current pass through a loop it will produce a magnetic field. One of the basic parts of a detector is an oscillator; it will produce the alternating current. Magnetic field is produced when an alternating current or electricity pass through the transmittal coil which is present in metal detectors. So, when a metallic object or a conductor is present close to the coil, it will generate a current in the object that will produce another magnetic field on it. There is another coil in the loop that can be found in detectors that is called the receiver coil that can detect magnetic field changes because of the presence of a metal or a metallic object. The latest metal detectors use these technologies; VLF very low frequency PI pulse induction and BFO beat-frequency oscillator. Let us discuss about these technologies:

Very Low Frequency (VLF) Technology

The most common technology used in metal detectors is VLF. There are coils in sets of two which is the receiver and the transmitter coil. The coil where electric current is sent and creates magnetic fields which constantly push down to the ground and pull back is called the transmitter coil. Magnetic field gets generated by the metal detector which reacts in any metallic or conductor that passes on it. When it encounters the object, the electric current and the magnetic field is formed around the conductor.

In reciprocal, the receiver coil is protected from the influence of the magnetic field which the transmitter coil produces and it is only affected by the conductor and /or the metallic object's magnetic field. The electricity that runs on this receiver coil produces a magnetic field that is weak when a conductor gets near the metal detector. In turn the coil will amplify and send the frequency of the electricity that has the same frequency with the magnetic field that comes from the metal to make analysis in the control box. Through this, the metal detector that works on VLF (very low frequency) will be able to determine disparity among the kinds of metals, the depth of the position when being detected.

PI Technology

A single coil is used in the PI technology (pulse induction) that is feasible on both transmitter and receiver. However, it is also possible to use 2 to 3 coils. Metal detector that works in this kind of technology can send a short burst and /or pulse of current in the coil that will generate a shorter magnetic field. In every pulse, the generated magnetic field will reverse the polarity and will eventually collapse. Electrical spike can be created and will last in very short period. When the magnetic field, pulse and spike collapses, a known current called as reflected pulse will occur and into the coil it will run. This reflected pulse can only last in seconds.

The reflected pulse can last in a longer period when a metallic or a conductor will get contact with the metal detector. The reason of this is caused by the opposing magnetic field that is produced by the metal detector. Metal detector is a device that has an integrator which contains a sample circuit that can be monitored closely on every spike. The thing that convert the signal, reads and amplifies will convert the signal into a direct current. The connected audio circuit when getting the right amount of electricity will produce tones that indicate a presence of a metallic object.

BFO Technology

The beat, frequency oscillator is like the VLF (very low frequency) that uses two wire coils. The first coil of the device can be found in the control box, and in the search head lays the second coil. The first coil which can be found in the control box most of the time is smaller compared to the second one in the search head. The two coils on the other hand, stay connected in the oscillator that sends out number of thousand electric pulses per second. When the pulse passes through every coil radio waves can be created and the receiver that can be found in the control box collects them all.

After this you will hear clear tones like the radio wave frequency which is created by the receiver. The current of electricity that is moving in the coil in the search head will create a field of magnet that creates a new field of magnet around the metallic object as the metal detector passes over the metals. The creation of radio waves from the search head coil is being interfered by the magnetic field created by the metallic objects. This produces a change of tone in the receiver this changes can helps in detecting the object in being targeted.

There are certain types of metal detector made through this kind of technology that we can see in our everyday life. These metal detectors can distinguish the difference between objects and know the place that they are in and not just detect the metallic target or objects with electrical conduction. We hope this metal detector article can give you the answer to your common questions with regards to how these machines and mechanism works.

Little Known Repair Tips for Your Metal Detector - Hobbies

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 red, which generates an opposite current in the coil, which induces a signal indicating the presence of metal. There are certain features needed for certain places the device is going to be used for. If you intend to use it on the beach, the terrain wont be that rigorous. But you are going to need waterproof protection.

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. Metal detectors work on the principal of electromagnetism and their effects on conductive metals. The high-powered coil of metal, called the transmitter, uses the battery power to generate a penetrating magnetic field. As the electromagnetic field enters the ground, anything metallic will become charged with magnetism.

Little Known Repair Tips for Your Metal Detector

Are you into a metal detecting hobby? If so, it is important that you know how to repair your very own metal detector to avoid additional expenses. You never know how much repair shops will charge these days. Besides, you are not even sure of the quality of service they can provide. So it is best to start learning how to repair your own metal detector to save more of your money and earn more from your metal detecting finds.

To get you started, here are some do-it-yourself repair tips for your metal detector.

1. Non-functioning search heads

If you have a non-functional search head, try to analyze the condition. Check for any mud or dirt sticking on your metal detector's search head. If it is full of dirt, try to clean it up with a WD40. Squirt the dirt out by applying the solution abundantly on the bottom and top of the search head. It will be much easier now to remove the mud. You can also use this solution in cleaning your wellies.

By keeping your metal detector's search head and wellies free from mud you can use them for a longer period of time.

2. Store your batteries when not in use

As far as the height above the ground goes, you want to hold the coil as close to the ground as possible. Obviously, if you're working in tall grass you're maybe 3 or 4 in. above the ground. On the other hand, on a smooth flat beach surface, you can easily skim the coil right over the sand. As stated earlier, metal detectors could really be expensive. You can cut on cost if you cut on features. Try to look for the best bargain by enumerating the features you are going to need against the one that you can leave off.

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 detect-metal.info. In older parks check in front of bandstands or areas where people would sit, to listen to bands playing in the summer. Another good place is baseball diamonds. Check the infield and the area where the players would wait to play. Also look in the area that the families and fans would watch the game from.

A good way to view the purchase is to decide how much money you are comfortable spending. It is our view that you measure this purchase against other purchases you have made.

When buying a metal detector consider the price. If the metal detector offers the best features of a then expect it to be expensive. If having fewer features is all right with you, go for a less expensive one. Metal detectors can run from as low as $50 to higher than $800. In order to avoid any battery-related problems with your metal detector, it is best to stash them in the "fridge" when not in use. By doing this your batteries will last longer.

However, remember to place them on a lukewarm "radiator" an hour before you start metal detecting. This will give your batteries the opportunity to revive their functions.

3. Turn it off

Always turn off your metal detector before repairing it. This is to avoid any further dilemma. Best of all, try to avoid starting your repairs right after you have used your metal detector. Let the parts cool down before you start touching them.

4. Find a reliable repair shop

If you cannot do simple repairs on your metal detector, find a reliable repair shop. This way you avoid spending more on repair charges. Plus, you can be sure that your metal detector is in good hands. Indeed, you can fix or repair your metal detector without having to spend hundreds of dollars on repair charges or lengthy restoration, thereby, curbing your metal detecting.

Just try to remember these repair tips for your metal detector and you will surely solve the minor problems without the mess.
