Hello, everyone.
I come from China, like electronic small production, a few years ago is very despise metal detector made, think it is very simple, but the production down but found it not easy to do, the year before and two years, has been the difference frequency type. Until recent months that the very low frequency and pulse, now I use the universal plate as a hunter, a coin to explore 15CM, but yesterday produced by PCB, the detection distance of only 5CM, do not know why. Hope more exchanges!
The first post, no good, will give everybody have a look I just purchased ore radio need reed headphones.：D
