The Golden Mask 4Wcl is a coin and relics metal detector with a wireless search coil, very effective with its super-fast operation, perfect discrimination, and depth of detection. With a working frequency of 15kHz, the detector is very sensitive to gold and tiny objects made of low-conducting metals like gold, while being able to scan at very good depth in hard-to-penetrate soils. The wireless system, along with the collapsible telescopic carbon-fiber shaft is robust, lightweight, and super-easy to use and transport.
