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.
