Golden Mask 1+

The Metal detector is a fixed ground balance machine that operates at a high frequency of 18kHz. The detector is a redesigned special version of the original Gold Mask 1 + with added dual tone sound (DT) - ferrous metals are indicated by a low frequency sound, while non-ferrous objects are indicated by a higher frequency sound. With the DT sound, you hear the Iron signals, but you always know if the target is good or not. In fact, the Gold Mask 1 + DT is a new version of the 1+ UK model, but it works at 18kHz, making it more suitable for gold exploration. GM 1+ DT is designed for use in normal and moderately mineralized soils. The machine has very simple controls, making it ideal for beginners. With a high operating frequency of 18 kHz, the GM1 + DT is as sensitive to small objects and low conductors as gold. The signal processing engine is lighting-fast, so the machine performs perfectly in dump sites, separating the Irons from good targets (coins), even if they are positioned very closely. If you're asking why they produced the one-tone version, here's the answer: the one-tone version runs a little deeper in light soil, not so much, but there's a small difference.
