How are you my friends..... The stability of the metal detector is three meters deep
How do we reach the stage of stability in the sufficient detector and bfo devices
First: We wrap the coil in an organized manner using a wire with a diameter of (0.5-0.7) mm
Second: After fixing the file, we put the wax used in lighting on it
Third: We wrap the coil with thin tin foil used in homes to isolate it from the earth’s magnetism
Fourth: Isolate the files from the outside air using plastic tubes or inside a wooden frame
Fifth: Using ferrite material on small and large files in abundance
Sixth: the use of variable capacitors (radio tuner) in the large and small coils, two variable capacitors for each coil, a minimum
Seventh: Use capacitor No. 104 instead of capacitor No. 103 (100 nanometers instead of 10 nanometers) in all stages of building the device.
In the end, if you adhere to what I mentioned in the previous points, you will reach an advanced stage of stability for the device, God willing, and God is the Grantor of success
