Golden Mask 3
The Golden Mask 3 is a typical relic and coin hunter, running at 8kHz for best depth of search. This detector can reach great depths, separating securely good targets from trash on all types of ground. GM3 has manual and auto ground balance modes. In auto mode the machine runs with speed priority with speed similar to the GM1, while in manual ground balance mode it reaches maximum depths, even in very tough soils. GM3 has a V.C.O sound frequency modulation audio mode for easy identifying the type of the target. A really professional-grade detector.
