Hello morgan, just to ask you few questions on the pdk i built following you coil information, that is 40 turns, .30mm wire and 6 cm diameter. I tried 2.2n to 12n capacitors but it is less sensitive. I am referring to my crt tv as initial test since my buried target is still one month old.
I experimented several capacitors and found out that lower capacitor value just like 500 picofarad or lower, the pdk create a strong capacitance that touching the potentiometers, that is, the gain and sensitivity it will beep. The same is true also when my hand is near to the coil, it will beep. Also, a quarts watch at 5cm can also be detected. Those findings did not happen to the capacitors 2.2 to 12n. I also found out that placing the sensitivity knob to its proper place is very important.
According the instruction on your pdk, the point of sensitivity is reached when a beep is heard by touching the knob and turning the sensitivity to its triangle mark. So i think that capacitance plays a role of the phenomenon detection. Please comment...
