How to choose a metal detector gold
The basis of the metal detector consists of two elements: a coil and a control unit. Due to electricity, the coil forms an electromagnetic field that reacts to a metal object. The control unit correctly interprets the signal coming from the coil, and is also responsible for the control and setting of the device. Electricity, for the work of a metal detector, comes from batteries, batteries such as AA or “crown.”

As soon as the metal object falls into the range of the detector, the device emits a characteristic sound, thereby alerting the user about the find. The tone can go from a low sound to a higher sound, depending on the proximity to the object and its magnitude. The screen also contains all the necessary information, including advanced parameters, such as: the exact identification of the object, the type of metal and its value, the depth of the target.

What to look for



The depth of metal detection is one of the defining characteristics, it largely depends on the frequency of the detector. Low frequency (5-7 kHz) is best suited to identify large objects at great depths, but small, closer to the surface of the earth, it will not see. High frequency (18-100 kHz) is used to search for coins, gold nuggets and other small items.
The deep metal detector usually uses a concentric (mono) type of coil. Another type, Double-D, works at a lower depth, but with a noticeably larger area, such a coil is effective when working with highly mineralized soil.

An effective metal detector necessarily has the function of discrimination. With it, the device will cut off the garbage metals (tins, beer lids) from the valuable, alerting the user only about the latter. Pinpoint mode helps determine the exact position of an object in the ground, making it easier to excavate. Another important setting is the balance of the ground. It allows you to adjust the sensitivity of the detector to find valuable items in the ground with high mineralization. Depending on the metal detector model, there are manual and automatic settings, as well as pre-set parameters.

For convenient carrying, the metal detector has a different design. Its weight plays an important role, lighter - better. This directly affects the user’s fatigue, especially when working long. There are fully airtight devices designed for underwater search. Some models are equipped with headphones. They are a closed type, which allows you to sensitively capture each sound signal detector, without irritating the surrounding people. Nothing prevents you from using your headphones, most likely you will need a adapter for a quarter-inch jack.

How to make a metal detector with your own hands



It is very difficult to make a fully working and, above all, effective metal detector on your own. This requires sufficient qualifications, experience, a tool, the necessary details and an abundance of free time. Without a working metal detector and documentation is also impossible to do, they will have to look for the vastness of the network.

Most likely, in the end it will turn out that the tool itself, if and can find the metal, it will be anything, but not gold and valuable coins. Even if there are any in the ground. Lack of flexible settings and discrimination make the search process inconclusive. However, if the purpose is only to study the device, we have something to share.

Do not be surprised, but the smartphone - really a universal tool - looks good and in the role of a metal detector. This is possible thanks to the built-in sensor, the magnetometer, which we usually use for navigation as a compass without knowing it. To work, we will fit any smart device on iOS or Android. Just download an app that’s easy to find in Apple Stores and Play Market on “metal detector. You won’t go on an adventure with this, but with the search for wiring in the wall and other communications, it will help.
Making a coil for a pulsed metal detector with your own hands
The simplest metal detector can also be made from all available improvised means. We will need an analog (non-digital) radio that works in the AM range and any calculator, with or without a speaker. Set up the receiver at the highest frequency (it should not catch the radio station), we need to hear static noise. Then we take the calculator and attach these devices with their backs to each other. Pick up the position so that the sound becomes muted, it may take some time. You may need to place them at different angles relative to each other. When we succeed, we’ll tape them. To make sure our homemade metal detector works, check it on any large metal object. You’ll notice that when you approach the device, you’ll see a characteristic signal. And the closer, the louder the sound gets.

Which metal detector is best to buy



Do not be embarrassed by the wide variety of models on the market, only a few of them are interesting. Given how much the metal detector costs, the choice of a quality device will be responsible.

Even the most advanced high-end metal detector does not guarantee success. The device is simply not a magnet for jewelry. Therefore, choosing the right place is a fundamental factor in a successful treasure hunt. Determine what you’re looking for. For example, coins or relics. For the first is to walk on the park or the beach. For the second, to search with a metal detector is better on the past places of people’s parking, here will come in handy old cartography.

To make it as easy as possible to choose the right metal detector, we’ll only introduce you to the best devices in your category. We will help to find the right device for a specific task.
