Golden Mask 4ProW is a very fast and powerful metal detector with wireless headphones. The machine works at 18kHz and thanks of this frequency, it is very sensitive to small objects and low-conducting metals – small coins, jewellery and gold nuggets. The detector has super-fast recovery speed making it the ideal choice for searching in trashy areas, especially if equipped with a small-size search coil like the new 23 cm Spider coil. Thanks to the manual ground balance, this detector goes deep in the ground, indicating even the smallest metal objects under the coil. With the wireless headphones (included in the kit) you hear the weakest sounds from the deeply buried coins or gold nuggets. The GM 4ProW is identical to the original 4Pro model, with wireless transmitter and wireless headphones added.
