Surely you have seen a metal detector in movies or in some series. With these devices we can find all kinds of metallic elements underground, but evidently fiction in this case surpasses reality. But don’t worry, because there is good news. As we said, you can do it with your mobile through different applications. Do not expect to find gold or metals of great value, since these apps are limited to finding metallic objects that you have dropped in your house or on the street.
Before downloading any application, you should know that if your mobile is capable of detecting metals it is thanks to a tool that it includes. Its about magnetometer, and it can also be called digital compass. Not all mobiles have this function, but the vast majority already have it. Its main function is to detect magnetic force that is in the environment, which allows us to detect metals easily. Even so, these must be of a considerable size and located close to the surface, since they do not have much power. What’s more, this tool can be used more for pure entertainment.
This application measures the magnetic field around us thanks to its high precision sensor. When we approach any metal, the level of the magnetic field will fluctuate. All you have to do is open the application and move your mobile in search of metal objects. Includes various levels of alarm according to the position in which we find ourselves, notices Y effects sound of all kinds to guide you better. Of course, the precision of this depends on your magnetometer, and for it to work correctly you must be away from electronic devices, since it detects the presence of their electromagnetic waves.
This application has more than 100,000 downloads in Google play, and was awarded the award for best metal detector app of 2019. It is completely free, and includes an easy-to-use interface. When you open it for the first time, your phone will display a quick reading of your surroundings to position you correctly. Then you will have to configure the microteslas, the basic unit of magnetic induction, setting the values between 0 and 59. Once you have configured everything correctly, you simply have to move the mobile to go in search of metals. The closer you get to the surface where you are going to search, the precision will increase considerably.
With more than a million downloads, this application has a very simple and user-friendly interface. You can use it to find cables electrical on the walls, tubes of iron, coins… and everything you can think of. The magnetic field will show up on your screen through different colored lines, each of which represents the three dimensions. As we get closer to a metallic object, the app will emit sounds and vibrate with greater intensity. You can change the sensitivity of these from the settings. As it says in the description, do not expect to find gold, silver or valuable metals.
This application includes quality graphics when we are looking for metals. In addition, it shows us the microsteel measurements of the last 15 seconds in a certain area, in addition to informing us about the minimum and maximum intensity of the detected magnetic field. This can be consulted at any time in case we have lost sight of an object. On the other hand, in his description he urges us to calibrate
the phone before we start looking. This is achieved from the application itself, and we just have to draw the Pattern of the number 8 in the air.As you may have noticed, all applications have very similar names. This app is one of the most complete for detecting metals due to the good features it has. As we move our phone over any surface, it shows us results of magnetic waves in the format analogical Y digital. It works effectively in finding iron, steel, nickel and cobalt objects, among many others. Its sensor detects signals from metallic objects in a range of up to 30 centimeters, and it will notify you via a beep.
This application can be tested on all types of surfaces to find metal objects. It is able to detect large quantities metal separately and when it does, it will emit a continuous vibration. The levels in the diagram have maximum and minimum peaks to correctly inform you if there are metals nearby. Its only point against it is that the search range is very small, so we will have to get quite close to the surfaces.
This application teaches us to manufacture our own metal detector. The creator claims that rings of gold at a range of 20-25 centimeters. In addition, for objects more large can detect them at more than one subway away, such as pots or pans. Of course, you must bear in mind that you need elements that you will not have on hand and you will have to buy, such as copper wire, capacitors and transistors, although in the tutorial that it offers you can easily build your detector.
With more than 100.00 downloads, we find another application that is very easy to use thanks to its simple interface. It basically follows the same operation as the rest of the options on the list. When you move the mobile across a surface, you can comfortably read the measurements and see their levels Maximus and minimous. When it exceeds the maximum, the phone will begin to vibrate more intensely to warn you that you have a metal object close to your position. It works better outdoors than indoors.
And we finish the list with this application that, in addition to detecting metals on any surface or terrain, is also capable of doing it on the human body. Includes a body scanner very easy to use that allows us to search for metals such as rings, pendants or bracelets. When it detects one, it will emit a sound that will increase in intensity as we get closer.
