Metal Detectors

CS770XD - Audio Disc (CS-770XD)

Switch on and start detecting. Listen to the loudspeaker signals. Good targets are high tones. Bad targets give a low tone. It seems like such a simple idea but isn''t this every treasure hunter''s dream of a detector? This CS770XD employs C.Scope''s ''non-motion'' technology, much favoured by professionals for the meticulous search technique which is possible with this style of detector. The CS770XD is optimised for inland and beach use. The CS770XD is such a smart concept, we reckon a fair few detectorists at all levels of the hobby will be eager to get their hands on one.
