Great Detector
Guest in Australia -This is a great machine but lacks sesitivity to small gold because it is an PI detector, the main claim to fame is that it works in highly iron mineralised ground. In zero to moderatly mineralised ground a Good VLF detector with similar power output and coil size will out perform it in all respects with the exception that it is not as sensitive to some hot rocks as VLF's can be.
