Hello everyone,
I keep this forum but I've never participated. I have seen that many people constructed their own PI detectors and I would like to contribute a bit. I am manufacturer of search coils and I can provide you with information on how they are constructed. Here you have attached tables where you can check the parameters of a PI coil metal detectors to manufacture it without LC meters.
I hope it is of your utility.
regards
