The best metal detector for Android, the Gold Detector 2021: Hidden Go! app can find hidden alloys and metals, such as gold, silver, copper, iron, lead, and more, in objects and the environment. It can also detect any metal-based plates that may have been buried underground.

How can the app find hidden metals?

The app uses the magnetic field sensor of your Android device to detect metals. It can detect any metal that has a magnetic field, even one that is not in the range of the normal magnetic field. This makes the app suitable for detecting and finding any metal, including gold, silver, copper, iron, lead, and more.

The app also has an option to turn the audio beep sounds on and off.
