The search for gold is one that has fanned the fuel for adventure and enterprise for many generations. It has been thousands of years since the valuable mineral has been discovered and used.
Initially for adornment and as an offering to the gods and deities, it was eventually used by modern man in different applications. In today’s setting, gold is used for everything from tooth fillings, cutting equipment, decoration and as currency. Its value has continued to rise over the years. Now more than ever, gold is actively traded in the world markets and so the search for the shiny yellow mineral has become more advanced than ever. Finding a Pot of Gold Mining for gold may be an effective method for extracting nuggets from the deepest recesses of the earth, but the method had cost thousands (if not millions) of lives over the centuries. The environment has also borne the brunt of this abuse, and so alternative methods towards finding the proverbial pot of gold are being tried. One of these new methods is metal detecting for gold nuggets. Metal detecting may not be your preferred method if you’re a large company looking for a large output of gold at the end of the day. However, for small-scale operations or for people who want to try their luck at finding gold, a metal detector is a safe device to use and one that does not require a specific skill set to operate. It is also a very helpful tool for prospectors who want to first make sure that the area they are looking to mine really does have gold in its veins. Why Metal Detectors? Finding gold nuggets through the use of metal detectors is a new development in the area of gold mining. A metal detector, as you may already know, is a handheld electronic gadget that is able to sense metals and objects with metal content even if they are buried deep underground. Gold is classified as a metallic element and so, technology has been applied to make finding it easier. Metal detectors have been overhauled and made more advance so that it can detect traces of gold under tons of earth and rock. In fact, several international companies have invested their resources in developing high-powered metal detectors for this purpose. It makes the job of prospecting potential mining sites easier and gives more accurate results compared to the methods they used before. While it is true that metal detectors cannot isolate gold when it does its searches; advancements in technology have allowed companies to develop metal detectors which can distinguish gold nuggets from iron trash. There are countless metal detectors of different varieties. Each one has its own system and the feature of each one was designed for a specific use or function. Metal detectors that find gold nuggets are generally powered by electrical energy. It pushes power onto a coil which in turn generates a magnetic field. The magnetic field reacts with the metal element or material underground and the device then senses and measures the degree of reaction the object or element is giving off. For the purpose of metal detecting for gold nuggets, modern metal detectors have been fitted so that it can look for deep caches and even treasure. Other than gold nuggets, metal detectors are also useful for finding rare coins and hunting for jewelry which may have been buried in the earth or even underwater. The same principle applies anyway, since gold, in whatever shape and form is still extremely valuable. What Metal Detector Should You Get? If you’re considering getting a metal detector to find gold, you should first ask yourself a couple of important questions. First is how much are you willing to spend, and second is what is your end goal for buying one? The reason you have to set some parameters early on is because you have to establish what kind of detecting you want to do. There are people who only want to make a hobby out of metal detecting for gold. This means that the metal detector will be used a couple of times a week or only during vacation time. If this is your intention, you’re better off with an ordinary metal detector – one that is general purpose. This kind of metal detector is still effective in looking for gold nuggets. The advantage is that because it is general purpose, you can also hunt for coins and pieces of jewelry in various places. However, if you’re serious about metal detecting for gold nuggets, it is advisable that you get the metal detector which has been specifically designed for gold nugget detecting. Be forewarned though, this kind of metal detector isn’t exactly cheap, but for serious gold hunters consider this as a business investment. It does pay off in the end. Metal detectors for gold nuggets still have various types. There are metal detectors which are very sensitive and can detect even small gold nuggets buried very deep in the earth. Others are able to find gold even in very metal-rich soil. Finally, metal detectors are also classified by the size of the coil it has. The bigger the coil, the larger the electromagnetic power it releases, and the larger reaction from the metal it is able to receive and sense. Technology and Metal Detectors: Metal detectors are classified as either VLF also called induction balance and the PI technology or pulse induction. It may sound technical, but it really is simple. Induction balance has the energy in the coil going up and down, like a sine wave. This allows the metal detector to sense even small gold nuggets. The downside is that the readings can be compromised because this type of metal detector is affected by mineralization in the soil. Pulse induction on the other hand, has the energy going on and off for a brief period of time. This allows it to sense the presence of a metal or metallic mineral. This type of metal detector can sense large chunks of gold even they lie deeper in the earth. PI metal detectors are also less sensitive to mineralization and this is why more mining operations make use of this kind of metal detector.
