This app will help you to find
resonance frequency of Metal detector coils
This app will scan your coil then show you the resonance frequency of your coil!
This app use headset microphone input to connect to the coil!
To build the measuring leads you will need:
1 - MiniJack 3.5 with 4 pins.
2 - Capacitor of 1mF
3 - Capacitor of 100nF
4 - Cable
It is very easy to build and then you will able to measure the resonance frequency of you MD coils.
Sometimes MD VLF Coils lose sensibility and it is dificulte to find where is the problem.
This app will scan your MD coil then you will see if the problem is in the coil or not!
