High voltage PI

It used to see the forum always said that the voltage to improve the coil does not increase the depth of the pulse detector, but I have passed many experiments, with 36V, the detection distance increases by at least double

Going over 18-24V requires quite bit of change in the design otherwise the mosfet and the damping resistor and op amp input resistor will blow up due to overheating; even if you have low PPS and low TX on times. I have not seen improvement in the detection depth going over 12V. Minelab uses 7-8V. BTW "pressure" is used for air etc. Perhaps you've meant "High Voltage PI" ?

You don't have to make too many changes, you just have to increase the power of the damping resistor, you can use any frequency of a few hundred Hertz, you can imagine how much power your induction cooker has
