Metal Detector - Metal track value play online

- Metal Detector app is simple to use, just open it and move it around. If the magnetic field values rise there is metal in the area.
- How it works
This app uses the built-in magnetic field sensor of your smart phone.
First of all after running this app if your phone shows high reading then immediately keep it away from everything to set it normal (0T 59T).
The normal Electromotive force (EMF) field level is about 59T (micro Tesla) or 590mG (milli gauss); 1T = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beef sound.
