About this app

Metal Detector is in the 3rd set of the Smart Tools collection.

<< Metal Detector apps require a magnetic sensor (magnetometer). If this app does not work properly, please check the specifications of your device. >>

This app measures magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, magnetic field level will increase.

Usage is simple: Open the app, and move it around. The magnetic field level will constantly fluctuate. That's it!

You can find electrical wires in the walls (like a stud detector) and iron pipes in the ground.

A lot of ghost hunters had downloaded this app, and they had experimented as a ghost detector.

The accuracy depends entirely on your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, PC, microwave) due to electromagnetic waves.

* Main features:
- Alarm level
- Beep sound
- Sound effect on/off
- Material design


* Pro version added features:
- No ads
- Compass
- Sharing GPS location
- Qibla finder, Car locator

* Do you want more tools?
download [Smart Compass Pro] and [Smart Tools 2] package.

For more information, watch YouTube and visit the blog. Thank you.

** Metal detector cannot detect gold, silver and coins made of copper. They are classified as non-ferrous metal that has no magnetic field.

I needed a metal detector to find the pins that mark the corners of my lot so I could resolve a property line dispute with a cranky old neighbor. After downloading several metal detector apps, I found this one to be the most accurate and have the best user interface. I probably looked a little crazy sweeping my cell phone, taped to a wooden pole, back and forth in the backyard, but in less than 10 minutes, I found and exposed the 3 pins I was looking for. Check and mate! Thanks metal detector.

This app is amazing. At first I thought it was fake but when I put metal in front of it it went off the charts, but when I put my hand in front of it nothing happens. Amazing metal detector,but sadly it would be hard to detect anything in a house since everything is slightly medal,so if the object is to far away you won't notice,but it is still an amazing app, you should download it and incase you were thinking I'm not a bot and I was not paid to say this,but now me saying that proubable makes you believe me less, ohh well.

Definitely should be renamed as magnetic field detector instead of metal detector. It does do this job quite well, but the sensor area on my phone it uses has to be within about a half inch of ferrous metal to register anything at all. As near as I can tell it uses the compass sensor in the phone since the "calibration" is exactly the same as calibrating the compass for GPS or star tracker apps.
