If you have a metal detector, this app can be used to find out if there are any metal objects near you.

It works as a magnetometer and detects the magnetic field strength.

The app is very easy to use. Just install it on your mobile device and open it.

The app will then detect the magnetic field value in μT (microtesla), or mG (milli gauss).

To find out what the magnetic field strength is in your area, just enter your location and click the "Get Value" button.

The app can be used as a metal detector.

It can also be used as a tool to measure the strength of the magnetic field.
