### 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:



MY WEB PAGE : https://www.neco-desarrollo.es

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.
