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.

This is a great app for measuring magnetic fields. I put it on my microwave and it got to 669 microt's. The one problem was that it started to glitch and stopped being accurate. It also stops graphing at 200 microt's. It is still really fun to play with.

Doesn't pick up a reading for an aluminum carabiner but will pick up other readings like a floor in a public building and metal casing over an electrical outlet, so whether it is any good for any kind of prospecting for coins, jewelry or gold or something probably remains to be seen. Maybe that's what you need the magnetometer for.

Yes it works: it beeps with the cover of a can, it's all i had to test it with for the moment. However, i thought it would give me more distant in the 3ft from a metal, but instead it beeps only within a range of about 6ins & detects through the camera. I can still get by with it & thanks to the nice lady who share on the video, bye.....
