Do you wanna find gold and other metals? Do you wanna find air tags, gold oura rings, golden nuggets, and more? If the answer to any of those questions is yes, then you are in for a big surprise! With the help of our application, you will be able to find gold and other metals. The application uses the built-in magnetic sensor of your phone to detect metals. This sensor is used to detect the presence of a magnetic field.

The application uses the principles of geocaching. In other words, it is based on the idea of finding a certain element in the environment. The element that is to be detected is hidden, and the only way to find it is to search for it in the environment. 

The application is very easy to use. All you have to do is install it, open it, and start moving your phone here and there.
