The Golden Mask 1+ UK edition runs at 15kHz for better
performance on high conducting metals and more stable work on wet and
mineralized soils.
The detector has the same lightning-fast recovery
speed as the original 1+ model, the only difference is the operating
frequency. The fixed ground balance means you just turn the machine on
and it is ready to indicate your next find. You adjust only the
sensitivity and discrimination levels - the recommended values are in
red, so you can manage very easy if you are running the machine with the
best settings.
The iron is indicated with a low-frequency sound, while
the good targets are indicated with a high sound.
