earthSCAN 

Golden Mask 4Pro is a top-of-the-line metal detector. The detector works at 18kHz and thanks of this frequency, it is very sensitive to small metallic objects and low-conducting metals - small coins, tiny jewellery and of course - gold nuggets. The detector has super-fast recovery speed making it ideal for searching in trash-polluted areas, especially if paired with a small-size search coil.

Thanks to the manual ground balance, the Golden Mask 4Pro detector could go deep in the ground.
