Actually, you might want to set the frequency. Originally he had it set at 222Hz for gold and several years later he said he was using 225Hz. Some of those DDS frequency generators have a frequency counter on them. Think silver is 335 . Don't know how far you can adjust these, but 466 works for silver but you might not be able to tune it that far. There is a set screw for each frequency inside the transmitter.
