Real Metal detector Smart Hunter - this app will help you to build a metal detector very easy
You will need:
1 - A arduino
2 - A MOSFET irf740 (you can you, any you have disponible MOSFET)
3 - A capacitor 1mF and 0.47mF
4 - A wire ( 0.54 - 0.7 mm ) for the coils. We need make to 2 coils, 80 turns both, of diameter 160 mm both (for more sensibility we need to use biger diameter).
5 - A switch
6 - A handset with mini jack of 4 pins
7 - A resistance of 10 k
How it work:

Real Metal detector can detect small objects like a gold ring at distance of 20 - 25 cm.
The objects with diameter of 16 cm, can detect at 50cm.
The objects with diameter of 25 cm, can detect at 100 - 150 cm of distance.
When metal detector detect any metall smartphone do vibrate!
THis metal detector is easy to build and powerfull

In the video tutorial you can see how it work and adjustes of metal detector.
For build the coils we use the wire of 0.6 mm, but you can use from 0.4 to 0.7 mm
The coils must be identical.
